I just got some 12 volt red leds from ebay and installed them in the projector lense housing. Drill a 5mm hole in the bottom of the housing and epoxied the led in. Do you have HID Projectors in your truck? That is the only way the "Terminators" work right imo. Had to cook the healdight assemblies at 200* for 10 minutes so the lense would come off with little effort. The seal is butyl. Installed the halo's and Terminators, run the wires through another hole I drilled in the bottom of the housing and epoxied that up, installed the lenses back on the housing and cooked again for 10 minutes and seated the lenses before the butyl cooled.
