Default Looking For A Ground

I recently installed a headlight relay kit to increase my headlights intensity. My problem is I can't find an available ground under a bolt head, etc.on an all fiberglass front end. I used a jumper wire and connected all four headlight ground wires to the frame to check the relay kit's operation, and it appears to function properly and headlight intensity appears to be brighter. Anyone had a similar problem finding a ground in the proximity of the headlights?

Run it up the wire loom, break it out where you want.

I put a nut on the end of one of the bolts that comes into the side of the radiator support for an inconspicuous ground.

the alternator is right there. Theres a big bolt on the back of it with a large ground wire attached. I just ran a short ground wire to that bolt. I have about 3 hooked there now. I got the positive for that kit off the horn relay, it has a big positive wire straight to the battery on a bolt on the relay. real handy to get to and right there were the relays go.

The rad support may already (don't know your year) have a ground screw for the lights / horns. Down on the drivers side, midway or lower on the front.
I installed a stud in the same spot to act as a ground for various things I've got up there.
