Hell ya, PIMP style....
Note to everyone, this window control LED swap was the biggest pain in da ass out of the others in my opinion. Mac and I had problems from them not lighting up at all (blown fuse) to the electronic locks being fully "automatic" (Mac can tell you about that one HAH).
The pics of the insides look different because one is of the passenger side and the other is of the driver side, and ones upside down.... to remove that optic thing, just wiggle it good and pull up at the same time. Don't worry, it'll come off...and it wont break as long as you dont apply TOO much elbow grease...
The LEDs were from www.allelectronics.com and yo should use a resistor no lower than 480 ohms...just my suggestion
