Got these on your car?

[WRX]

The lights im really interested in because of safety I would not mind having brighter tail lights cause of all the fog around where I live. Specifically I was wondering if they were only plug in play or has someone had to add load resistors etc to make the leds work properly, turn signals blinking too fast or what not. If they are simply plug in play I would swoop these up. They are pricey so Im hoping maybe someone has some exp with this brand and can chime in before I take the plunge.

The lights are from superbrightleds.com
