Hella H4 conversion headlights installed
I converted the headlights to an H4 type. I went with the Hella lamps as they look similar to the original 7 inch headlights and one has to really look to notice they are not stock.
After much research on 67-72chevytrucks a Forum, I purchased a wiring harness with built in fuses and relays and the lights online. The Hella lens are very nice quality - they have glass lenses and metal reflectors.

I routed the new headlight harness along the existing wire mould along the radiator. Power comes directly off the battery. I mounted the relays on the fender near the battery.

Illumination is significantly improved over stock.
