Any ideas what would cause this? Neither DRL is lit now, and when I go to high beam only one high beam comes on. Last night I flicked to my high beams and they both came on for a brief second before one of them burnt out. The only thing I have done recently is install a bt-45 TOY bluetooth adapter as well as replace my cabin air filters.
I believe that the high beams and DRLs use the same bulb, just with a lower voltage for DRL. So why would the DRL not come on at all, but the high beam still work?
