Calling all E53's with HID's in the H3 Projector Fog lights!

[Ricky Bobby]

X5SND and I have recently undertaken the popular projector fog light conversion with the Depo H3 projector housings (the ones that came on the pre-2003 cars), but we are also in the processing of installing H3C Morimoto HID kits in the housings as well.

Now, he is farther along than I am and reports some issues of moisture build up on the inside of the housings, and had to install additional vents. However, he is the first documented case of moisture build up I have seen, and I theorize it may be due to an alternate bulb wiring method. He used a wiring method which left the rear "cap" on the housing completely intact, whereas all the install methods we have seen have some variation of running the bulb wires through the back cap of the housing, and either sealing up the hole with silicone or using the rubber grommet installed on the H3 bulbs to seal the hole up.

Those of you that have installed H3 HID's in your fog light housing (H3 projector version only), have you had any moisture build up issues, and did you drill out the rear cap of the fog light housing to utilize the grommet for the HID bulb wires?


This would be helpful in figuring out how to avoid moisture build up for others who want to perform this mod, thanks!



EDIT: Please see most recent post, could someone that has the Genuine BMW or TYC projector housings (not Depo's) pop out their fog housing for me and snap a few quick pics, I'd like to see if the Depo's are missing a vent! Thanks!
