After installing new OEM headlights Xenon AHL, my daytime running lights still doesn't work. Had it replaced because the original headlights were finished. Brand new H8 DTRL bulbs. I had also resetted the short circuit to the light module using BimmerGeeks Master license. Is there a fuse, relay, or something else that keeps my DTRL from not coming on? I noticed reflection from cars and windows sometimes that my passengerside DTRL does come on and when I make a complete stop it cut off. Where do I start to diagnose the problem? Thanks

 

Your H8 DTRL bulbs - halogen or LED? Just replaced one of mine, decided to stick with the conventional bulb because of what I read regarding problems with lower power draw with LED bulbs causing the light module to shut down the circuit.

 

Check the headlight assembly wiring. The wire insulation is notorious for exposing wires.
