Forget Retrobrite??? the lowest cost H4 reflector headlight test
By skrit
I paid $18.37 including tax for everything you see and picked up from my local Toyota dealership. I plan to use Amazon LED lamps in them if they perform better than halogen. Comes with wiring harness, relays and halogen lamps. They appear to be much better quality than the standard ones (shown at the left). My goal is to have a headlight similar to Holley Retrobriite at a fraction of the price. Once I get my lamps, I'll do a test to show beam pattern and light output.
