I have these 2 LED I want to use
10mm WHITE 15000mcd LED-MPJA, Inc.
and
ULTRA WHITE 10000mcd 5mm LED-MPJA, Inc.
I know I need to add some type of resistor to the LEDs. I am experience at electrical work, but I just dont know how to figure out what resistance. Im thinking about using them to replace the original LEDs in my halos in the headlights. The biggers ones seem way to big to fit. but if I can fit them then I will use them.
How can I get these to work?
