Install takes about 10-20 minutes depending on how small your hands are...follow DIY for changing angel eyes if you want to do this.
I bought the 7500k hoping to get a color match of the LCI brow after seeing that the 5800k looked exactly the same color as stock. Results turned out pretty well since i have my angel eyes at 14volts each. Pic comparisons are below because that's really all you guys want to see.
stock bulbs at stock voltage:
sun from the side
full on sun 100% brightest it will ever be outside
same as before, zoomed in
for 20 bucks I'm gonna leave it at that. it was these or the lux 5000k and i don't want to wait months + spend 250 bucks just to get a color match with my LCI brows.
they can't be beat for 16 bucks if you have a coder in your area to up your voltage. If these didn't look good I was going to go with OSS but these satisfy me for now.
Later today I will have pics of these GP thunders VS my roommates new DTEC 20 watt LEDs. I'm betting that mine show up better in the sunlight but we shall see.
