I upgraded all of my headlights, tail lights, etc. to LED. I upgraded the housings as well but am using the original wiring harnesses. I also installed a new flasher module that works with LED so I wouldn't have to install resistors. Additionally I had to replace the DRL sockets as the originals were shot. Everything works perfectly when the headlights are off but once the headlights are on the signals don't work and both turn signal indicators on the dash stay lit. I've done some reading and think it may be a bad ground but I have no idea how to fix. Any advice is appreciated. Thanks! Tim
