Most clearance lights I've seen have incredibly cheap connecting hardware inside them, basically the wires pinched in a slit in some thin metal.
I believe the lights are run in series. Either the ground wires were run in series across the cap - one to the next - simply connected to each light by the rivet holding the light to the cap or on my old RV, the lights were grounded to the metal skin of the unit.
I suppose it depends on how many wires you have going to each light?
