New Guy with some questions

Hi everyone, I just purchased a 1997 Land Rover Discovery. So far i love it, I was wondering if anyone had upgraded the headlights to xenon or the silverstars? Do I have to replace the whole fixture or just the bulb? Also does anyone know where I could get a used brush bar besides ebay?

Thanks,
Will

if you wanna go with silverstars or something youi just replace the bulb. I belive #9003 is the ones your looking for.

Thanks!
