A while ago I did the DRL disable by grounding the DRL wire to the OBD-2 bracket. But every now then when I hit a decent size bump on the freeway at night my lights freak out. My DRL light on the dash will flicker and my headlights will flash between the headlights and the DRL's. This will go on for 1-5 seconds. This doesnt happen during the day on the same road, just at night. Any ideas on why this is happening? Has anyone else had this happen to them? Thanks.
