That's where I got my kit from. I posted this thread a while back and only one guy responded to it....made me sound like an idiot for doing it and he couldn't see any change. I however think its one of the best mods I've done to my car I always hated the amber bulbs.
You will need a good pair of long tweasers to hold the tiny LEDs in place to solder them. The covers just pop off with a small screw driver.
If this is your first soldering project you might want to enlist the help of a freind that has some experience.
Note some of the switches have a red LED in them, door lock, defrost and seat heaters. make sure to take note which one to replace. I made the mistake of replacing them bolth. Granted to say I could not find the red LED in my Pile of used LEDs...they all look the same. Now my door lock lights up amber instead of red.
