Just installed euro headlights from TYC on my SDL. They look great and the work great except now the lamp failure indicator on the dash comes on with the headlight high beams and when low beam and fogs are on at the same time. No indication with just fogs or low beam. I suspect the bulbs have too much resistance but I'm not sure how the sensor works. Are these low-quality bulbs? Would better bulbs solve the problem? Anyone had this problem on a euro swap?
