EXTREMELY DISAPPOINTED > DEFINATELY NOT PLUG & PLAY AS FALSELY DESCRIBED! Wasted $200 to replace the 2 x 3 pin low beam lights and 2 x 2 pin high beam lights for my 1985 GM truck. Seller sent 4 x 3 pin high/low beam lights. When installing the 2 pin plug on 2 of the 3 pin high beam located lights, all 4 lights flash on and off continuously. Seller says I need an extra $45 wire harness. DO NOT BUY
Just purchased this headlight set from "OCTANE LIGHTING", supposed to be Plug & Play. I switched the ground connection on the upper low beam lights as recommended with poor results. I'll never recommend Octane Lighting to anyone.
Just installed four H4 halogen headlamps to replace the original sealed beams.
Top photo > on low beam, all 4 headlights illuminate at less than full capacity
Lower photo > on high beam, just 3 headlights illuminate at full capacity
Note: All headlight plugs are firmly connected.
