alright, i've got about $800 in lights, and will continue to add more. i've got the stock battery and alternator, but i'm upgrading my battery to an Optima Yellow Top next week (due to 2 dead batteries in 2 nights ). the lights are illegal while driving (i got a warning from a Statie), but in the little town of Coshocton, they don't seem to care. i usually only have them on while i'm in town, cuz the lights don't glare as much with all the ambient light from streetlights, however, once i leave town to go home (i live about 17 miles away in the middle of nowhere), i just turn the interior ones off.
