Hi,
Long time lurker, first time poster. I had the lowbeam go out on my 88 c10 (the fastest color). I have replaced the bulb but no help. when the low beam is selected the head lamp indicator is lit on the dash and the bulb is dim. I think I remember this being discussed on the old forum as a switch issue. I wanted to check with the experts here before I started with the screwdriver.
Thanks
Alton
