Modular lighting system for N gauge rolling stock

[SNCF stephen]

Hello

 

I am trying to find if a lighting system exists that I can buy off the shelf or can construct very simply to add directional lighting to a DCC equipped loco. At the moment I have a number of autorails that have tomytec chassis that I would like to add lighting to but designing my own system is a bit beyond me.

 

If any systems are out there that just require soldering to the DCC decoders two spare wires the. That would be ideal.

 

Many thanks
