Brake/Running Lt Diagram

[99silver]

Here is the diagram and Radio Shack part numbers for converting a single wire tail light (pilot LED light bar) to be feed as a brake and running light. Note the diodes are directional feed, so the end that has the red tape/silver band goes towards the light.

I saved this from before the crash and I don't believe it has been posted again so now its here. I am running the Radio Shack parts on mine with no problems.

Mother this is the you were looking for.

Yep, that's it, I gots two of them made up!

The schematic calls for a 330Ω resistor and the parts list calls for a 150Ω resistor.

Which did you end up using?

The other thing missing is the wattage rating of the resistor. If you use a 150 ohm resistor it should be rated at 2 watts. If you use the 330 ohm resister it should be rated at 1 watt.

 

Also remember that the resistors will get hot in use. Do not tape them next to another wire's insulation or they could melt the insulation (depending on the type of insulation on the wire). If possible install them in a way that allows them to dissapate their heat to the air.

I used the 150Ω . The Radio Shack #'s are the ones to use, just did the light bar on my trailer with great results as well.

I bought a package of little resistors from The Source (Canada's version of Radio Shack) today, (they came in a four-pack), and I think there's a couple of 150's and a couple of 330's.

 

Can I use either one? (I'm only replacing the resistor, cause its end is broken off; I think the diodes in my setup are still OK).

Thanks for any enlightenment,

:sun:Great to hear about this setup. I checked with Radio Shack in my area and also checked online. The only resistor I could find there was the 330 ohm .5 watt. I went ahead and used this. Do you think it is large enough to hold up. Right now its working OK. The light bar only pulled 150mA.

Thanks
