Thanks Marty.
I found this response on a Soundtraxx Yahoo Group;

This suspiciously sounds like what you are talking about. I did download the manuals but, to be honest, its like reading a foreign language sometimes. It takes me sometimes a few re-reads to absorb this kind of info. I'll see what I can pull off tonight. For my purposes originally, I am/was going to wire up both the head light and back up light to F0 function. However, the idea of being able to independently control the lights in intriguing. That said, I think I'll stick to the plan and get them working first. :oops:
So if I read this manuals and quoted response, I need to program CV's 33 & 34 with a value of 1 in order to map the function to turn them on.
Then for the LED compensation I need to enter the appropriate values according to the manual. For CV's 49 & 50 I would then program the CV's with a value of 192 for simple on and off.
I was able to determine that the LED's are wired properly by touching one of the leads to the function output and touching the other one of the truck wires. So the LEDs do light.
I'll try again tonight.

Quote:I agree on the 680 ohm comment; I am tending to much higher resistance values.
Also note that the Sountraxx units require adding "128" to the the value
identified in the programming manual when using LEDs. Honestly, I am not sure
what really changes when plugging that in, but it does affect the lighting.
As for wiring of the LED, the light power is DC, and the LEDs are polarity
sensitive. Easy way to remember wiring out leads is to connect the long lead on
the LED to the blue common lead. The resistor can be on either side of the LED
in the circuit.
As for programming, I like to be able to control the headlights independently
and have set up the following standards for my layout:
F0 - Headlight
F5 - Strobe/Gryalight/Rotary Beacon
F6 - Backup Light
F7 - Dim
To do this, I program the following CV's:
CV 33 - 1
CV 34 - 1
CV 39 - 2
CV 49 - 129 (for LEDs)
CV 50 - 193 (folr LEDs)
CV 51 - 136 (for LED's as a rotary beacon. Refer to the Soundtraxx manual for
whatever other effect you might like)
Hope this helps.
Regards,
Detlef
