Mine has never worked since i got my truck i took it apart and took bulb out and stuck a test light in the socket and i didn't get any thing it was a dead issue now im just wondering if anyone knows if it could just be the bulb if so what kind of bulb is it because that is a tiny bulb or is their a fuse of something that goes to it or could their be a short some where just if anyone has any info i this i would sure appreciate it i just can't stand something not working on my truck lol.
