Re: Brake Light?
Im working on a self contained 12v lighting system.
So, a 12v jell cell and off the shelf automotive/motercycle lighting equipment.
Now.. to the purpose of the the thread, im working on a LED brake light that uses a $7 harbor freight submersible trailer indicator lamp.
The circuit is very simple.. two 4005 diodes, and a 550 1/2 watt resistor.
Activating the brake light function is accomplished with a roller blade switch.
So... take banded sides of the diodes and pig tail them. On one side of them, tie in the resistor, and from there the positive side of the battery.
Hook up the negative side and the lamp should light up at half voltage.
Now.. on the other diode, run that through the N.O. side of the switch. And hook up the common side of the switch back to the common hot wire.
When you press the switch, the lamp will get supplied with full voltage and will be fully illuminated.
