Sure. The LokSound Select Micros allow for two different behaviors to be programmed for the Front light, Rear light and Aux 1 & 2. In the LokProgrammer, you access these on the Function Outputs tab. Here, set Front Light [2] to be a dimmable headlight, and set the brightness down to where you want it. On the Function Mapping tab, on the row that starts “Reverse, F0”, add the newly created front light 2 to the physical output column.
Decoder Pro works the same way, you just can’t give the newly defined output a custom name.
