Does this kit have everything needed for the swap?
I have used halogen replacement in the 64 Falcon and 67 Ranchero for years with no problem. I love them in the Ranchero (it has quads).
But I just installed them in the 70 Cyclone Spoiler and when all 4 are on I'm breaking the circuit breaker. At this time I don't know if the new lights are the problem or not.
Did you use a kit or just sourced parts? The circuit breaker on the light switch or one that was in kit/sourced?
Can try a larger gauge wire carrying the heavy loads.
If its the light switch breaker I'd suspect the light switch.
Anyone convert their Falcon to newer style headlights (where the bulb is seperate from the lense). or HID's?
I am debating on adding suplimental lights and using those long range offroad. But I am not sure I want to drill a hole in my bumper.
