    Alright, this might seem like a dumb question, but I'm having an issue with the marker lights on my drivers side headlight assembly. The turn indicators are working, but I'm not getting any marker/parking lights at all on the driver side. Passenger side is working fine. I tried checking the fuse box but I'm not seeing anything out of the ordinary. I changed the inner most amber bulb two days ago and noticed the marker lights were flickering briefly. I tried checking the wiring and the bulbs after that and they seemed fine. Advice? Should I be re-checking the fuse box and/or wiring to the lamps?

    I'd concentrate at the wiring at the marker light if it's not the socket itself. Wires over the years can break usually at where the metal pin is crimped on it inside the connector or socket. What type bulb is it, #?

    If one side works fine but other doesn't it is wiring problem.... Go to this: http://supermiller.com/pdf/SK29863.pdf and scroll to page 12. There is a wiring diagram for the marker lights of your truck..

    I had a problem with the wiring harness rubbing through right where it attaches to the hood hinge.
