Any reason you dont want to use HID's in fog light housings? LED style will be off-spec regardless in terms of filament location so LED and HID bulbs are both essentially going to throw light differently than the OE halogens will.


low beam D2R

low beam D2R + fog lights 9006 3000K HID


I don't use these when there's incoming traffic, but the same challenges will be had with LED style bulbs. Both are going to shine the area differently from standard halogens.

 

I currently keep my fogs on all the time, because most road lines in my driving area (Ottawa + surrounding) are painted with zero to barely any retroreflective beads, so road lines are actually invisible at night when it rains, and when it's not raining, they're just plain difficult to see. My reasoning is that LEDs have lower light output than HID, but higher light output and can be tuned to 2800-3000K unlike conventional bulbs, so I would blind oncoming traffic less with LEDs than with HIDs, yet still be able to light up the road in front of the car and cut through fog.

HIDs will definitely light up the road in front of the car, but I don't want to blind oncoming traffic. I suppose I could try to install HIDs and just aim them really low, but I'm thinking LED is a good in-between solution. I want my fogs to be reasonably street legal to run all the time at night, as opposed to giving law enforcement a reason to pull me over.

 

I am also looking for yellow bulb for the fog lights. From my understanding (someone can correct me if I am wrong here), you do not want to have a lot of lights in the foreground because that will mess up your night vision. hidplanet has a lot of information on the tech of headlights and anything you ever want to know about HID, LED etc.
