    THank for the previous help. I have one last question as of now. The LEDs I bought as Radio shack are 1.7v for the red (brake light) 5.0v for the Blue (Bright indicator) and 2.1v green (turn signals). What do I use to get these to work with My 12V system. And what is the equation to find the right parts?

    Thankyou

    Mike

    They sell SPECIFIC LED's that say they are 12V parts. If not, you can get some at the local parts stores that are. They would have resistors in them or were designed to run off 12V. The ones you have now will require special resistors run inline to stop the 12V coming from the car to the LED.

    I'd swap them out. I know they make the 'correct' ones because I bought the ones that were installed on a swapped out dash cluster.

    The lenses in the cluster are colored... You can use 12V white LEDs for all of these.

    I used the standard bulb in the High Beam indicator.
    It was way too bright using a forward firing white LED.
    (Very annoying to have a bright blue light shining in your face on a dark night.)

    Got it figured out. Was able to get an article with equations from the electric parts store.

    1K resistor should be fine.
