LED Running/Brake light circuit

[mattdaelectrician]

I went and got the parts to do this project and had to buy in bulk so if anyone wants one of these circuits http://www.gadgetjq.com/ledrearwbrakeflash.htm $6 and I'll send ya one pm me if interested.

What exactly does this mod do? Is it turning your turn signals into running/brake lights?

After buying the circuit from you, what else would be involved?

[mattdaelectrician]

this circuit lets you hook an LED type light to your bike and have them run as running lights and brake lights there are 3 wires 1 hooks to the running light wire 1 to the brake light wire and 1 to the led light your hooking to bike. the circuit takes the running light 12 volts and lowers it to 9 volts so the led runs dimmer when you hit the brake the full 12 volts is applied to the led.

Jared ......did you buy a new bike yet?

[Jared]

Why would you have to run LED lights for this mod to work?

[mattdaelectrician]

well unlike incendescent lights that have dual elements LED to run as running brake lights need a lower voltage to lower the brightness of the lamp. this circuit is for running leds as running/brake lights you don't need it to run leds but to run leds as running/brake lights you will need something like this circuit

[Jared]

Interesting. Where can you get direct replacement LED?

[nightmare]

I have found that most leds that you buy if stated as a run, brake and tail do not require that extra circuit, it is built in

[jestephens]

You don't need any extra circuitry to convert your brake/run light to LED.

This Kuryakyn circuit is needed when converting all your Turn Signals to LED.

See the electrical forum for a brief description of my experience converting turn signals to LED without load equalizers.

I might just be confused thouth. The circuit on Gadget's page is a different circuit than the link to Kury.

this circuit is not to convert any existing lights. this circuit is to take a 12 volt led that you can buy at wal-mart auto zone or tractor supply that has no circuit built in to make is run at 2 different voltages which is needed to had the led as a running/brake light all it contains is a risistor and some diodes. somewhere throught the conversation and questiong someone got the discussion twisted. I repeat this circuit is to take any led light and provide 2 voltages to make the light dimmer in run mode and bright in brake mode. NOT TO CONVERT, MODIFY, OR CHANGE ANY LIGHT THAT IS STOCK.

to futher the conversation I will explain the project in which I needed to make this circuit and I will post a video that I'm working on to show. On the stock 08 licence plate frame there was a red reflector that I removed and replaced with an LED light that I bought from autozone and 4 LED bolts for my plate I connected this run/brake resistor diode circuit and the leds run dim and bright with the brake the top led cost $5 and the 4 bolt leds cost $8 and the lights are very bright.

Think of it as simply an inexpensive way to make a standard strip light LED function as a Run/Brake. I have made up this circuit (wire/resister/shrink tube..) and have it in my tool box waiting to install it. I am planning to put an 8" LED strip under my trunk.

I'd like to add a strip of LED's between the chrome strip and the saddlebags. This sounds like a good way to achieve the goal. Now to pick the LEDs. . .

that is exactly the purpose of this circuit.
