Hello all,

I have just got myself some new lucas toggle switchs to work my lights, rear heated screen and what not.

Does anybody know how to wire in a led light to each toggle switch so that when the switch is on the led will light up to indicate its on?

I know that I could obviously see if the light are on and dont need a led but I think it would be nice?

Any help will be much appreciated

Miles

Fairly easy the output from the switch going to the rear screen put to the + leg of the led and earth the other leg

Different LEDs will work best with different resistors.If you know the operating max current (7-50mA depending on colour)of the LED you can calculate the resistor.
Resistor value= 12volts/max current in AMPS

Did you have any issues with the hazard not being red?
