Alright, just got my PIAA leds installed yesterday! definitely much brighter than the halogens that originally came with the lights. It was tricky tucking the led controller box inside the assembly but with enough finesse, it went in. Also, i had to bend one of the tabs on my left light in order to keep the bulb seated. The heat sink is heavy, so if its not seated very snuggly it could cause the headlight to pop out of adjustment. I didn't have any issues with it bouncing around during my test drive yesterday and my drive in to the work today. So far so good!
