[AT] Also Slightly Off Topic,Car with blue light power trouble

[Phil Auten]

I believe y'all have covered this pretty well,  but I don't remember 
anyone mentioning

wiring the lighter socket directly to the battery.  Put a fuse in the 
line that will handle

double the current drawn by the lights and that should handle it easily. 
Remember to

use the KISS principle.
