This product was extremely easy to use. The instructions were complete and detailed. The difference in light output is amazing. Chevy should have added this feature in production.

Very clear directions, really assists in lighting up the road at night. Completely dumbfounded why GM did not include this configuration of all four lights on at the same time.

I had been looking at/for this kit for a while, and was surprised to find it on sale here for about half the prices that I had seen online since last summer.This is a great add-on for my 1994 Suburban (and any similar Chev/GMC trucks)! I still need to polish or replace the cloudy composite headlight housing, but just the difference between having both high and low beams on, rather than just the high beams is dramatically better.The only (and much easier, lazier) deviation that I took, from the great directions that came with it, was to route the primary power lead into one the several hot leads on the terminal block, on the passenger side firewall, rather than going all of the way down to the starter solenoid as directed. The wiring, and particularly the relay and the supplied mounting block that it attaches to, are of a much better quality than typically seen in your neighborhood auto parts store or retail electronics supply "shack". Writing this highly recommended (and uncompensated) testimonial for both Painless Wiring [...]was even easier than the installation.Semper Fi,Dave
