lol, im flattered that i inspired you
(you know i DO have a life outside of micros you know

)
actually i was out running around because the bank screwed something up and that needed fixed. and i had to go to walmart. and mcdonalds

for ONCE they didnt screw up my order so this is a good day
as for the LED, it is a blue(obviously) 2600mcd, 3.7v typical, 4.5v max, 20mA, 5mm LED. if you do it the same way as i did, you may have a hard time fitting the porsche on the chassis. try the pt if this is your first time, it is a nice car, purple and that teal greenish that they came in look great with a blue under glow. i used a CR2032 lithium battery. if you want to fit smaller bodies on there and more easily, then get a smaller battery. anything that is 3v will do good.
