I don't know how much this will help everyone, but i saw a lot of posts on here about adding led lights to your cars, and since i am no electrician i decided to look some stuff up. Hope this helps some other people out there too. Have fun.

The second site seems to be more helpful, but the more options the better i say.

 

also found this for calculating resistors and such
