I've pondered this as well.  I think the simplest, but maybe not the best,
is to run the wire along the rain gutter and down the vent to the engine
compartment and then get the high current direct from the alternator.
Install a relay back there so that you can turn them on and you are set.
This way, if you use big enough wire you will have move volts running up
there as you are taking it from the alternator rather than the battery.

I like my Syncro Westfalia with the big bush bar on the front with the Hella
Rallye 2000s on it.  I can light road signs 5km away!  Very simple to get
power to this location!
My Syncro 15 Doka had roof lights which were wired via a hole with a rubber 
grommet about 1�" from the bottom of the gutter. The wiring appeared to have 
been run just to the inside of the B-pillar.
