Headlight Relay Kits

I made my own with a couple of $5 relays. Not very hard if your under hood wiring is in reasonable shape and not too brittle.

I also made my own, but have a relay for each filament. (4 relays)
If one relay feeds both low beams and one feeds both hi beams, then the loss of one relay takes out both lights.
Didn’t like that idea much.

Also all headlights are now 10 ga. wire including the grounds.
