Chopper, Unless you add BUNCHES of these lights, and only if your battery and/or altenater are weak, they will not make them get dim.
They are NOT wired in series (remember us talking about a single ground from front to back to which you could connect all your ground wires?).
The most difficult thing you will run up against is pulling wire through the spaces that are full of the pink panther (INSULATION).
Oh, by the way, you might want to make sure the ground between the trailer and the Tow vehicle has good integrity.

Have no intention of arriving at the grave safely, but rather to skid in sideways, chocolate in one hand, throttle in the other, totally worn out and screaming
"WOO HOO, WHAT A RIDE!"
