HID fog lights

drossel · 02-09-2007, 07:58 PM

i helped a friend of mine install a no-name HID kit he bought off ebay into the fog lights of his 2007 335 coupe. it worked fine with the engine off. it did set an error in the OBC, but the error went away after a few seconds. however, when we started the car, the fogs started to flicker like crazy - they almost looked like strobe lights. after about 30 secs of flickering, the right side fog light went off and never turned back on.

we switched bulbs with the left side but still no luck.

i've searched and the consensus seems to be that mtec has the only kit that works with E90/92's. does anyone know why the cheap HID kit we installed on flickers when the car is running? i searched, but couldn't seem to find the answer. TIA

this is the kit we tried to install:

u need a resistor. the stock lights run much higher than the hid ballasts. i think the hid bulbs are 35 watts and the oe bulbs are 55 watt. u need to equal out the volatge.

I don't think that is the case... he states.. his friend's 335 coupe.. which is H8 35watt.... so must be the cheap crap....

You do need a resistor or a special HID fixer thingy. MITE46 details the install of some nice ricy HID fogs in this thread

would you need a resistor with the mtec kit?

also, i don't understand why using a relay to draw power from another 12V source instead of the fog light circuit would eliminate the flickering. it's still a 12V source either way, no? unless the power for the fogs is being fed by a module (GM)? but that doesn't really make sense because they're just fog lights.

We install those here all the time, you need to use 2 resistors per side.
