Switched to LED bulbs a long time ago. Currently at over 100k miles and my driver side light went out. Initially thought it was the LED and thought it weird it went out so early. Took it out replaced with a new LED and still no luck. Checked the F12 and F13 fuse and both are fine. Even switched them around to make sure and no luck still. Relay is good since the passenger side light works still. Any other parts I should check? BTW high beams still work. I'm thinking it's a wire somewhere. The next step I'm contemplating is checking with a voltmeter everywhich way I guess.
