I'm in the process of converting a Farish Class 25/3 diesel to DCC sound. I also want to install front and rear lights which it lacks. I believe all the lights in the real engines were red tail lights, but just wanted to check your good selves before I commit myself to installing red LEDs and fibre optics in the holes I have drilled in the dummy headlights.

A locomotive would display white light in direction of travel on the front marker lights or headcode panel when lit and red lights or tail lamp on the rear to signify train complete.

Hi

The latter light fitted version has a white headcode and 2 red marker lights at each end, illuminated depending on direction of travel

Out of interests sake, which decoder, speaker and sound file are you going to use?

Thanks for the info, which confirms what I thought. The only lighting I can't do much with is the headcode, which is just printed and stuck onto the body, so there's not much scope for backlighting it, especially as I hope to squeeze cab lighting in as well.

As for the conversion, I'm using a Zimo MX660 with sound files from YouChoos, a small (12x8x2.5mm) speaker in a custom 3D-printed enclosure of my own design and a SACC16  stay-alive system. I've replaced the 5-pole motor with an 8mm diameter coreless one from Tramfabriek, to which I will add new flywheels and universal joint socket if I can't get them off the old motor. I will also mill down the top of the chassis by about 1mm at both ends to accommodate the speaker and SACC16.

It's also worth remembering that for most of their working lives only one of the tail lights was likely to be lit.
