For just the light bar? Psh, get some KC daylighters if you don't care if they're kind of bulky. Your battery should be fine as long as you don't run them while they're off. Had my day lighters for about 3 years and they've definitely withstood some beatings. If you want slims, I guess you can go for the PIAAs, or if you want to save some of that money, some people I know run the Hella 500s too.
