How did you get a gound to all your lights?

How did you gound all your lights on you speedster. I guess i need to run a common wire across the front light and tail light and ground it to the frame but I want to see how you did it first. Also is there a bulb that goes in the bottom of the head light bucket? If so what it the part # for it. One last thing what it the Part # to the turn signal bulbs?

Thanks
Mike

The front harness grounds to the beam bumper brachets on both sides with a third wire going all the way back to the dashboard, and bolting to the suport there. All this stuff is 12 Gauge
The rear harness has two grounds on all three light fixtures that bolt to both rear frames on each side and also has a wire going back to the dash . anything else that needed grounding tags on to it with solder even the Alternator.

I don't think you need a part number. Take one of the bulbs out and match it up. Dual or single contact. Match up the little side tangs to the replacement. BTW, make sure it's a 12 volt bulb.
