Auxiliary brake light wiring

Flyinfool, you ARE the man.

Your little almost free wiring gadget works perfect.

Thanks again.

 

OK, here are the instructions to with the diagram that I posted above.

 

From Radio Shack you will need;

1 pack of diodes P/N 276-1661 (4 pack) $2.69

1 pack of 330 ohm resistors P/N 271-1113 (5 pack) $1.19

You will also need some wire #16 or 18 AWG (Preferably at least 2 colors) and some heat shrink tubing.

 

This is enough parts to make 2 assemblies.

 

Take 2 of the diodes and notice that one end is marked with a colored band.

Twist the leads of both colored ends together and solder.

Add a piece of wire to this twisted end and solder.

Twist one lead of a resistor to the free end of one of the diodes and solder.

Attach a wire to the other lead of the resistor and solder.

Attach a different color of wire to the free end of the remaining diode and solder.

Slide a piece of heat shrink over the resistor and diode long enough to cover the solder joints.

Slide a piece of heat shrink over the other diode and its solder joints.

Shrink both of these down.

Slide another piece of heat shrink over the remaining wire connection and overlap the now covered diodes and resistor and shrink down.

 

You now have the same thing that you can buy already done.

 

The end with the single wire goes to the positive lead of the LED brake light.

The lead with the resistor goes to the running lights circuit.

The lead with just a diode (the one you put a different color wire on) goes to the brake light circuit.

The negative side of the LED brake light goes to ground just like normal.

 

SEE, Be careful what you ask for.........

Ok got my brain wrapped around how to do this now but a couple questions.

 

How many lights could this handle ?

 

Could this also be used for side marker lights on a 4 wire trailer using two of them giving you side marker turning signals and brake lights can't figure out how to take the brake light out of the equation.

 

haven't seen any small led marker lights with dual elements.

 

 

 

This would work the same with side markers.

Just take the above directions and everywhere you see "brake" substitute "side marker"

 

Side markers are usually just a few LEDs, You could easily hook both side markers to one controller.

And for my next trick. I have designed a couple of mixers to allow a center brake light, AND have it work correctly, on a 4 wire trailer.

I need this for mine before the trip to MD.

I have a solid state version for those with a little more electrical ability and a relay version for those that are a little more electrically challenged.

So far I just have the circuits drawn, I still have to build them to verify all of my math.

Dude you have had all winter what have you been doing its almost time to ride. :stickpoke:

Working 3 jobs....

Barely time left to breath or even enjoy a good fart.

I have LOTS to to on the bike and trailer before summer gets here tomorrow.

 

Maybe I'll have stuff left to do AT both Dons MD and WI MD, other than BS, cause trouble, eat and drink.

 

That reminds me, time to order more parts for the pile of things to do........
