I Ran power Direct from the Battery instead of the High Beam line. I often go into my camp or into places where the extra lighting with the key off and lights on for a few minutes will surely help. Also I've seen ppl grounding there lights too the roof via Self tapping screws and all that, but why drill the roof at all I Ran Slightly heavier Guage back to my battery the same way my power came up and it works just fine.
I assume I am "ppl"

Heh!
Anyway,
Good automotive electrical system practice indicates that running a wire all the way back to the battery does not supply an adequate path for the return current. This is especially true for high-power accessories such as lights and audio amps. Grounding should be done to the body of the vehicle as close to the accessory as possible to reduce return path losses and reduce RF interference with other electrical systems. When you run a short ground wire to the roof (doesn't have to be the roof) you lower the impedance thereby allowing better flow of the voltage to your lights. This goes with high-powered stereo amps as well.
Many people advocate running thicker (or additional) ground straps from the chassis to to body, motor and/or battery as it can improve engine power, mileage, your audio system and, in general, more efficient working electrical components.
A good example of this is when you are following a car and notice their brake lights flickering with their turn signal...this is suposedly an indicator of a poor grounding circuit. Grounding methods an locations are very important in a proper running electrical system (and RF installations for you HAMS and CB'ers).
That is why I grounded my light bar with 400W of lighting (nearly 30A of current) directly to my roof with two ground straps. My CB antenna is also mounted here.
Besides, it isn't your Jeep until you put a hole in it.
