Changed my handlebar light, had a cyclops 3800 lumen led bulb laying around as,a spare for my bike and decided to try it, took the light off the quad, the cyclops is a H4 style with removable adapters, took the adapter off and had to grind down the diameter of the mounting area to fit into the socket, got it to fit pretty good then had to drill a couple holes though the plastic and metal on the socket hole on the housing and put a couple short screws in to lock against the led on the plastic housing around the led but don’t screw into the housing then had to cut the short harness off that plugs into the bullet connectors to and add two female spades to connect to the males on the H4 plug from the led wired it to be on hi beam since it is a hi-lo beam led, did not take any pics of the install yet as I want to see how it holds up, not sure about how I have it secured the plastic in the light housing is brittle where I put the lock screws but here is a picture of the bulb installed and one with it on in the shop
