window switch light, now BLUE Options

I did this

finally.

I used a 5mm LED instead of a 3mm because Radio Snack didn't have 3mm ones. The 5mm is almost too big but still fit.

closer



and in the dark



I likey and the 5mm is very bright. Now everything is blue.

Yeah, but how many Volts?
In Sweden we don't have so many "by cool stuff to your car" stores. I can probably get hold of LED's but it would help to know have many Volts they should be....

Ummm LED's don't exactly work that way. They have a forward voltage drop of around 2-4V and an external resistor is used to reduce, say, 12V down and limit the current. The PCB under the window switch will have that resistor on it already so all you need is a standard 3mm blue LED. Don't get the most super brightest one either - standard brightness is way more than enough

I suggest you do a little research on LEDs though. there's loads of electronics articles that talk about them online.
