Jolly's running lights were unsteady so I removed the headlight assy. and found a loose bayonet,took care of that and Jolly's eyeballs are now shining blue as ever.Thanx again ,Dan.Whilst fumbling around with this I let the headlight dangle by the wiring.The ground wire pulled loose and the headlight dropped the 2.5 inches to the fender.Put everything back together,NO headlight.That little drop was all it took to waste the bulb,which absolutely was working before I took it out.Before it fell on the fender.I can see the separation of the filament.Must have been ready to go?Anyway,mite be good to be more careful.
