Hey at least you're honest. A lot better than the typical "installed my kit threads" that are light...
"DAMNNN...these bitches be bright man! Million times better than stock. I aimed them up higher since I don't have high beams!!!!one111!!"
Looks like 6k. 8k would look like a smurf and you'd know for sure. If its a crisp white/purplish hue, than its 6k.
As for the static, it seems common amongst kits but not so with OEM grade equipment. Probably has something to do with the cheaper quality internal components and the lack of better shielding. How was your harness hooked up?
