GREETINGS!

~I have a quick/simple question (for those of you that have been there and done that regarding this particular bulb change procedure)- how difficult is it to SWAP out the HIGH (bright) beam halogen bulbs on a 2007-2013 Acura MDX?

I've had a pair of SYLVANIA 9005 SilverStar Ultra High Performance Halogen Headlight Bulbs installed (by a friend) in the high beam location on my 2009 MDX for over 8 years (still running strong!!) and want to replace them with a whiter (not the HiPros, or the OEM stocks obviously) set of high beam halogen bulbs as it seems like the bright bulb replacement location isn't too difficult (no bumper removal?) to accomplish/gain access to on a 2nd gen. MDX?....

What tools might be required, and approximately how long should it take the average human being to complete this particular HIGH BEAM halogen bulb swap on a 2007-2013 Acura MDX? :nerd:

*also, there doesn't appear to be too much posted on this forum regarding high beam bulb replacement, which leads me to suspect that this task should be a piece of cake (which essentially translates into moderate level of difficulty for myself!)

i have my LED's for 4 years. would never go back to halogen. Especially for hi-beams and fogs.

glad you found success with LED usage for the high beam location on your '12 MDX :29:

have heard others complaining in the past that some LED bulb's overall light distribution (being used for high beam) is not as effective/widespread as some quality halogens like Sylvania/Phillips etc. :|

i had previously considered LED bulbs for the high beams, but at the same time, I rarely use my high beams and when I do it's really only on very dark interstate roads and/or to flash drivers when necessary....been fairly happy with the Sylvania high beams as they're very bright and have lasted nearly a decade?!

...just want to switch it out the BRIGHTS on my '09 MDX with some Phillips which may be a tad more white/bright as these Sylvania bulbs (which are bound to crap out any day now I'd imagine?)

on the fence right now on whether I should just have the installer (who'll be swapping out the stock HID low beams with some HID Osram CBI low beams on Saturday) take care of the bright bulb halogen swap as well- or if I should hold off being that this is something that's easy enough for even mechanically disinclined subjects as myself to accomplish...some bulb locations on the 2nd gen MDX are easy to access and swap out, and others, are just a PITA.

Usually light distribution is not so great in reflector, but not every reflector is made the same and not every led bulb is good quality. Hi-beam reflector dont have to have any cut-off, it is wide open. and pretty much every led bulb will provide much wider beam spread compared to halogen. This is why first LED bulbs was design for fogs.
I have spend alot my own money, just doing testing on different bulbs with different led chips. there are really ****y bulbs and there are some comparable to 50w hid bulbs.
Some attached pics from testing. and comparison OSRAm CBI 35w vs Novisight d2s LED bulb in D2S projector. Camera settings set so you could real difference between bulbs

Priscilla, the high beams are pretty easy to get at. You have to remove the plastic clip bolts on the cover over the radiator but that takes 5” & then you just give a little counterclockwise turn & they come out.

I just threw one of those HiPro Power bulbs in there on the passenger side tonight (also in that side DRL). They look good color wise though I’m not thrilled with the blue colored bulb (particularly on the highs). I’m going to order in another pair & do the driver side & just give them a trial run. [I have to admit, while I’ve complained about Sylvannia’s Silverstars longevity in the past, it’s impressive that these regular bulbs have lasted 9 years]

Thanks RainGoat!- I may give this another shot, during a short-lived attempt at work last week- some of those clip/bolts (securing the cover over the radiator) were a bit difficult to remove- may need some pliers or something to pry them out (next time)...

Also, going to call Acura parts to get the exact part # for these plastic clip bolts (securing the cover over the radiator) as at least 3 of these on my '09 MDX warrant replacing...:cool:

Please forward the part# on as I’m certain I’ll break some (though I haven’t checked my handy dandy trim set for a match yet).

Use a fairly narrow flat blade. Slide it into the groove & pop it up about a centimeter. Then put the blade below the outer rim & it should pop up & out. Occasionally, you can just grab them once they’re popped up & pull out the whole thing.

LEDs on high beam reflectors are not a great idea...
Aftermarket LEDs are still not designed for SPOTLIGHT USE (which is what the High Beams are) so you will end up with LESS useable light than halogens..
The Sylvania Ultra Stars work great I had them for a long time and they still amaze me how far the light reaches.

Use LEDs for Low Beam/Fogs until there is a suitable LED replacement for High Beams.

Hi Priscillababy,
Looking for an update... :)

Wondering if you ever got to the high beam bulbs.?
How easy / difficult was it..??



I got a decent set of 9005 LEDs [ I got them for my TL HBeams/DTRs.. but may not work out.. ]
so thinking of installing in the MDX..



Cheers
J.

Hello- i actually still have my SYLVANIA 9005 SilverStar Ultra High Performance Halogen Headlight Bulbs

I did make several attempts at changing out the high beam, but even this task was too overwhelming for me (not much space to work with and I'm not the type of person mechanically inclined enough to move things around in the engine area to make space) :crying2: :laugh:

Oh well- as the saying goes- if it ain't broke, don't fix it!!! :wink:

Alrighty then...
Thank-you skirmish and Priscillababy..
something to think about,,,
I have some el-cheapos 9005 on fog at the moment.. the colour temp and intensity are good..
but the bulb body are going to fail anytime now...
these new LEDs are bright as heck....!! maybe even too strong for fog or DTR


food for thought..

Actually MDX high beam reflector works great with LED's, it throws light much further compared to my infiniti's reflector. And it produced twice as much lux compared to oem bulbs...

I agree. I replaced all the bulbs including DRLs with LEDs but NOT the high beams on my 2010 ZDX with little effort and was very happy with the outcome.

You will be too.

I just put in the DDM Tuning Sabre 50w LEDs & I’m quite impressed. I actually bought them on sale for $75 for my Mom’s 4Runner but we didn’t think they were much different than stock, except for color. Previously, I ran PIAA 4100 K Halogens & those were pretty good (I’d run them for 16 years in my Pathfinder & 9 in my Mom’s JGC-they’re bright & last forever). As an experiment I placed those 100w HiPower Halogens for a while. Those bulbs work nice for DRLs but were pretty terrible as High Beams. I’m really pleased with the DDMs & will probably put a set in my Pathfinder once I mount my new JDM light housings.

Here’s a review on the DDM Tuning Sabre 50w LEDs by one of the 5th Gen 4Runner guys.

https://trail4runner.com/2018/12/03/ddm-tuning-saber-led-9005-review/

I’m not as enthusiastic as he is. Below is our test comparison. My Mom is 74yo & she feels she gets better contrast & can see better with the more yellow halogens. My ophthalmologist buddy says this makes sense as older eyes don’t do as well with the whiter colors. My 48yo eyes & aesthetic sense like the 6000K more but it’s tough to argue paying the $75 with this light comparison. The MDX lens appears to have a better projector for LEDs. I’m quite impressed with it & the color looks great (unfortunately I didn’t do a side by side comparison on the MDX)

I rarely use my high beams but when I do I want the really LONG AND FAR output...
My D2S Morimotos in Lows & Fogs got me covered in the near output so..
My question is, Are they really worth it for far output vs powerful Halogens? Cuz 100 bucks for a pair of LEDs aint cheap and I dont want them to fail me on the road like every other LED do.

From late March to late December [when the cottage is open.. ] I use my high beams extensively ...whether its in the TL or the MDX.


The property is well inside wilderness territory and the chances of collision with deer / moose / wolf / porcupine .. and on down to smaller critters can happen at ANY given moment...risks are even more so at night.


A LED upgrade would be a good idea IMO.. the sooner I can see wildlife... the better the survival chance for me/family and the critter...
looking for best results..
Thx

It’s a reasonable question. We use Highs alot when we’re out of town in the Cascades or on the Coast. I won’t really know what I think until then (the 100w HiPowers were terrible-even in town). I actually bought these for my Mom’s 4Runner bought she liked her stock Halogens better. The review article above says they throw farther but I’m dubious as they liked the near distribution better & I think the objective picture says differently (mind you, that’s out of our 4Runner, not the MDX - the MDX appears to have better projectors for the LEDs).

Definitely not worth the $95+ they are new if you don’t feel like changing. I usually spent $75-85 on a pair of PIAAs though so it’s comparable (PIAA are GREAT bulbs - years & years of use in a mainly off road vehicle). I typically carry spares but I’m concerned about Lows, not Highs (dual Low Failure & your immobilized, dual High Failure mostly annoying). Good LEDs should be more vibration resistant than Halogen but I’ve suffered Halogen failures with the PIAAs in like 7+yrs on my truck so pretty good.

But the MDX does not have projectors for the Highs its a reflective type which does not play nicely with LEDs for spotlight use aka High Beam..
I have used a lot of halogens for the Highs and settled with the Sylvania Ultra Stars which in my eye test have an output of almost give or take 50 miles from the MDX in the desert, Mind you the absolute maximum is useless for road use but it lights up road signs and reflective markings in the far distance quite enough that is distracting.
Sadly the yellow tint compared to my Morimotos 5500Ks in the Lows is off putting.

I wish the Highs were colder in temp so those LEDs might come in handy! but with no actual review for the MDX I am hesitant of spending 100 bucks to be the guinea pig myself :/
I know for a fact that el-cheapo LEDs (Sub 50 bucks) are useless for the high beams at least the ones Ive tried, The worst part is that not a single one could last more than a year of use either by the fan failing which causes overheat? or the LED simply burning out… They are cheaply made and obviously need to be higher quality thus more expensive to last, That is why I am curious for your input in the MDX using those...

My mispeak on projectors. Definitely reflectors.

I can’t recommend the PIAA halogens strongly enough. I have a cumulative experience of almost 3 decades with them & they are EXCELLENT. They are expensive but worth every penny, both in quality of light & durability. I ran them in my Path & my Mom’s JGC for >20 yrs total. Those 2 trucks saw ALOT of SW off-road use & I was amazed at how well the PIAAs stood up to it.

Your & @Priscillababy experience with Sylvannia is making me rethink my prejudices there. I ran the first generation of SilverStars on my ‘93 Maxima, which was purely a commuter & they wouldn’t last a year (this was ~2000-2004). I stupidly did this more than once thinking I had just bought a bad batch. As they were half the price of the PIAAs, I paid like 150% the PIAAs price for 1/2 -1/3 the longevity. I vowed never again but it looks like their durability is finally up to snuff. You should never say never.

PIAAs are available in different light temps. I always ran 4100K but that was back in the day. I find my G’s 5000K a little yellow these days. Again, having to rethink a little. My Mom is 74 & unquestionably sees better with light around 4000K instead of 6000K. A buddy of mine is her ophthalmologist & he says that rings true to the way optic physiology works-so there’s that.

I also ran the PIAAs on the MDX but must say it looks like I’m getting better lighting with these DDM Tuning Sabres. That said, I agree the jury is out. If you read that T4R review he touts farther reach with the LED - I’m dubious. My pair was intended for my Mom’s T4R but we weren’t happy with the result so I popped them in the MDX. It’ll be a year at least until I have any real idea (though those 100w 5000K HiPower Halogens were TERRIBLE as highs - I don’t believe the 100w at all & I’m even dubious about the color temp-they looked VERY blue behind the wheel. They do work great as DRLs however, especially given the sub $15 price).

Desert definitely has the toughest lighting demands so I agree you’ll know best on actual useful “throw”. My Path & JGC auxiliary lighting set up were for off-road SW desert as you simply need more & better light in the desert (my Path had 860w of Halogen light in a forward 180* arc). Here in the NW, you’re usually in a tree tunnel & even the coast is still trees on one side. Long distances forward on rare occasion but rarely a need for long throw peripheral lighting. We do have desert on the East side but it’s more like CO than UT or AZ. IIRC, you might be in Baja so I wouldn’t argue you have the toughest demands.
