Fog light bulb replacement

I would like to change the fog light bulbs on my 2015 JGC Limited Ecodiesel. I have the HID headlights and would like a whiter light on the fog lights closer to the HID color.

Are LED's possible without throwing codes? I'm OK with just a whiter bulb if that's all that's available.

Any suggestions? How much of an issue is it getting to the bulb area? Thanks.

Re: Fog light bulb replacement

There are a lot of good write-ups in the Interior/Exterior/Visual forum.

LEDs and HIDs are popular.

If you are going to perform any modifications other than a simple bulb replacement, the easiest access to the fog light area (except on a Summit) is by removing the lower air dam (remove 7 half-turn fasteners and pull).

Re: Fog light bulb replacement

I just want to replace the bulbs, somewhere in the 5000 Kelvin range for a whiter light.

XenonDepot has LED fog bulbs with a 5k color temp. Be advised these bulbs produce significantly less luminous flux than the stock halogens, and *far* less than what an HID lamp would produce. Naturally, the vendor wants you to believe the LED fogs are "just as bright, if not brighter" despite the objective, quantitative values.

If all you are looking for is a color match for the headlamps and you don't care how little light the LED fogs would put out, I'd say go for it. Otherwise, an HID kit is going to be your best bet... the HID bulbs will put out literally 4x the flux that the LED bulbs do.

Re: Fog light bulb replacement

Has anyone just replaced with a whiter halogen bulb like these?


H11 - Philips CrystalVision Ultra 12362CVS2 bulb


I really don't want to spend the $$ on a HID kit or the LED bulbs. I have replaced headlights bulbs with something like this and they did look like a cleaner white.


Thanks for your input. Wireman

I have tried several including those and they all look yellow next to the HID headlights. The best one i have found and what i am staying on until LED technology improves is the silverstar ultra. The LEDs just are not there yet i have tried a few and sent them all back. Give it a little time and a good bright, fanless plug and play one will come out. And maybe some better color options so you dont need to also change your 4300k HIDs to match them.

Re: Fog light bulb replacement

Has anyone found a good matching HID set for the fogs? I've looked at the phillips LEDs and they are expensive but they don't seem to have the light output HIDs have.

How do you like your 3k HID fogs? I just put a set in my wife's Audi and am considering the same on my Summit. Can you tell a difference over the factory color in rain/fog conditions? Advantages?

Re: Fog light bulb replacement

I'll look at the Silverstar Ultras. And the ZXE's also. I used the ZXE's in my RV and they were an improvement over stock bulbs. Wireman

Re: Fog light bulb replacement

Bear in mind the life of the Silverstars will be shorter than stock. That is my experience. By the way having had to change the entire fog light on the driver's side the best way was to take the tire off, remove the wheel well shield to gain access.

I would be concerned about pushing 3 times the light out of the fogs because the light spread and leakage will be significant. Nothing worse then seeing idiots using halogen housing pushing HIDs out of them blinding everyone.

I would expect that the 4300K to 6000K out HIDs will cause unwanted spread. I would like to see someone who has done this and see how good or bad the light through the fogs will be...

Truth. I haven't seen enough beam shots with the WK2 with HID fogs.

The 35W XenonDepot HID kits are notorious for melting the WK2 fog lamp assy. Somewhat surprising, but there you go.

If you live in an area that has a lot of fog (as I do), the 3K HIDs are awesome. They are considerably brighter than the halogens, and there is less noticeable backscatter due to the longer wavelength of the light. It takes a while to get used to the color difference, but they work great in the fog.

The design of these fog lamp enclosures is actually pretty good at minimizing any vertical light spread. The stock halogens are "masked" to prevent any direct light projecting from the bulb; if you replaced the bulbs with "unmasked" types, it would be like having your brights on to oncoming vehicles. The HID lamps only broadcast light to the sides (to the reflector) because of the way they are connected (end-to-end) to the harness.

This pic is really close to the garage door, and shows the demarcation between the fogs and the mains. On the open road, the fogs project directly out about 25 feet or so, then there is a 'penumbra' band of about 3 feet where there is bleed between the two lamps. At a few hundred yards out, the fogs are definitely noticable, but not as distracting to oncoming traffic as an unmasked halogen. I travel with my fogs on all the time, and have never been flashed by an oncoming vehicle.
