Evans Design BiDirectional LED Question

Have you tried reversing the leads and see if it works.  That is the only thing I can think of.   It may be also, the wires have to be attached to the reverse board for the light to work correctly in reverse...

Can not reverse leads there are two leads hot, one for green, the other for red, one black lead for common. Lights work fine when tested outside unit. The red light lead is connected to rear light output, the green light lead is connected to front light output and black lead to common.

Thank for the answer.

Red and green leds run on 1.8 to 2 volts, where white leds run on 3 to 3.6 volts. You may need a resistor on the colored leds. Are the installed ones still functional by themselves?

John,

Evans Design LED, specs require, 7-19 volts AC or DC. When I tested them before installing, they were tested at 12 volts and worked fine. They fail to work when wired with the front and rear engine light which are working just fine. All lighting is using the same common. It is definitely not the ERR board, the LEDs demonstrate the same behavior in two different units. All other lighting works as it should.

Thanks 

OK. They must have resistors and a diode already. If the common is the same, they should work. Needs more brain than I have.

The LED headlight output is around 3 volts but the Evans LED’s are set up for 12 volts.  There is not enough voltage to drive the LED with the resistor.

The Cruise Commander has plenty of voltage to drive LED's.  Note that you need a common anode three-lead LED for use with TMCC lighting as the light outputs are negative in respect to frame ground.  I've done many of these with directional markers using common anode LED's.

John,                                                           Will this work for my application?

I'm thinking you'll have to separate the 2 common/connected black leads if possible, then swap the black and the red to light the rear.

Note that John said common anode.

No, they must be common anode, like I stated previously.

Thanks for the help gentleman.
