Ok, these were installed before i bought the car, they are 6000k XENON headlights, no idea what brand. My lows work fine, but my highs don't. Not knowing a whole lot about vehicle lighting i figured the highs were produced by the fogs (which were stock) so i took them out, well then taking a closer look i saw a high beam bulb, and it won't light up. My father says it's a wiring issue, but i don't know how that could be.
