LED Lighting/Bulbs

It's nice that GM put in LED bulbs for the interior lighting and for the tail lights, BUT they didn't finish the package IMO.

The puddle lights (at the bottom of the door) are still regular bulbs.
Along with the license plate lights & the reverse bulbs, which look kinda strange & not as classy IMO.

Do higher trims get LED bulbs there, possibly?

Or has anyone else upgraded, or thought about upgrading, those to LED's to match?

I changed the tag bulbs to very low lumen, cold white LEDs, which, to me, match the dark blue far better. I'll probably address the others as they blow.
Premier trim.......all bulbs are LED including tag lights with the exception of reverse lamps, amber turn signals, halogen fog lamps and in door puddle lamps.

Probably something to do with saving money on a driver circuit with multiple LEDs to match the output of a tungsten bulb will do or could be restrictions on reflector shape housing size accommodating one halogen instead of multiple LEDs..

Glad the Traverse fogs are halogen.....forget about looking cool ........the LED fogs on my Sliverado may match the white headlamps but as far as lighting the 6 LEDs work like $hit compared to the 2 halogens on the Traverse.

Convesely, the LED headlamps on the Traverse do work much better than the Silverado but that is in the design difference The Traverse' 10 "D" shaped and 2 rectangular use multiple LEDs in 8 separate lenses for low and 4 additional for high beams and all 12 lenses remain lit on high....whereas the 2 lens Silverado lighting is always at full output and on low uses a mechanical shutter to chop off the top of the high beam.

So, in regards to the bulbs, the Premier only adds LED license plate lights over an LT?

What type of bulbs are they btw?

For headlights; I don't need no stinking bulbs! Simply test ride a Premier or High Country on an unlit road at night and decide if there are any other changes...major! difference..........they have LED D-Optic™ bi-function projector-beam headlamps

Greatest innovation since they switched from oil headlamps to tungsten bulbs. Six focused "D" and 2 rectangular LED low beams plus 4 auto dimming "D" high beams in an auto-leveling pod with all 12 operational on high beam output sufficient to spot a deer in sufficient time (especially with auto braking) to stop.....all without blinding other drivers!

Thank you GM. No longer mind driving at night on unlit back roads, instead of hitting deer, I'll simply sunburn them!

As I recall, they're T10 LEDs if that's what you're asking. If not please clarify.

Yes, what type, but I just noticed you have the prior generation though
LZ model '18 Traverses are almost all LED lighting with the exception of the reverse lamps and corresponding front parking lamp/ directionals .....temptation is to replace those few bulbs with LEDs for looks. Seems might be better to leave the stock incandescents and not try swapping with LEDs.

Like the 17+ Acadias I'm guessing that the bulb outage monitoring circuit in the BCM of the '18 Traverse is calibrated for the stock incandescent bulbs. As per the GM article below substituting LEDs in these circuits will cause continuous monitoring and result in a dead battery or other electrical issues.

I want/wish to only replace the license plate lights & the "puddle"/courtesy door lights to (matching) LED's...that's all

Has anyone replaced the reverse light with LED? I bought a pair of the 921 LED reverse bulb but notice the back panel has to come off if I’m not mistaken. Has anyone done this yet or knows how to removed it? I don’t want to do it without some advice since the lift gate is automatic.

I literally just removed the panel a few minutes ago to find out what bulbs were there.

There is a piece of plastic covering one screw that sits in the handle area to the right of the locking mechanism.After that screw is released, just gently pry off the clips starting near the locking mechanism and work your way up the sides. Once the sides are open, you can get to the bulbs. Just twist, then remove them from the housing. I just ordered some Phillips leds that I have on my other car that are 6000k white.

Thanks for the tip! I already ordered the bulb by matching the part # from the Chevy online parts catalog so I’ll try it out now! I ordered an eBay set I had on my Acura and they were great so we’ll see how these work out.
Unfortunately I installed the LED bulbs from eBay and they were extremely bright but when I locked the car to turn the lights off they would stay on but get very dim and never turned off. It looked amazing so now I have to figure out if this will be an issue with other bulbs.

Just curious, as I wasn't really planning on replacing them, for the part number?

I ordered these of Amazon - Philips 12789LPB2 Bright White Vision LED Back-up Light (921).

Ugh. Wish I would have known this earlier. I can confirm this happens to me too. Also noticed the instrument lights on the center console near arm rest also stays on.

I will contact The Retrofit Source and see if they know anything about this and maybe order their LED bulb which is $25 and hopefully it’ll work. The difference though with the 6000K LED was just amazing!

Well I guess the next gen Traverse contains a bulb outage monitoring circuit just like the next gen Acadia. So I guess y'all have to make a choice between amazing and dead battery/electrical problems.

Think this might explain why the light stays dim after the car is turned off??

On 2017 [next gen Acadia] models, incandescent bulbs are used in the backup lamps.[just like in the next gen Traverse] In some vehicles, LED lamps may have been installed instead. The Body Control Module (BCM) evaluates the Reverse Lamp circuit to determine bulb outages by applying and monitoring a low voltage signal. Since LED lamps have different electrical properties than incandescent bulbs, the circuit does not operate as expected. The BCM is calibrated for incandescent bulbs and, as a result, may stay awake after the key is off if LED lamps are used, causing the BCM to continuously monitor the circuit, which can lead to multiple electrical conditions.

I read on a Malibu forum a load resistor is needed. I'll be trying to install one tonight. The thread I read said only one light would need one...which sounded right since I vividly remember not having the led light on when only one was in the car and the other light was still stock. I'll report my findings. I'll be using the led load resistor I got from pep boys.
