Hi Sector, thanks for the input-
I haven't really had a chance the last couple of days to look at it, hopefully tomorrow. I have replaced most of the parking lamps, with no luck on curing the problem. Two of the sockets had some old dried electrical grease that I scrapped out, the others looked pretty good. I'll look at the wiring and headlight switch in greater detail.
I do have a hitch and wiring- the connector is pretty dirty, I'll try cleaning that.
I'll update if I figure anything out
Thanks
