Beejack, thanks once again, that did the trick. My problem stemmed from the fact that the PCB has the negative as the common. I had put together 2 small PCBs with surface mounted LEDs for the head/taillights but I had wired these with a common positive. Thanks once again for the help!

Beejack, thanks a million! I'll give that a go tomorrow and report back,

Thanks RAF, Here's the best pic I can get of the back of the pcb. Pin 1 is on the top row right as you look at it.

Guys, any help with this would be greatly appreciated. I have a Hornby class 56 PCB which I'm planning to use in a kit built loco but I'm not sure which terminals on the board to solder to for directional lighting. Here's a photo of the board: I know terminals 3 + 4 are for track power and A + B are the motor connections, and I'm pretty sure 6 is the common. Would any of you guys know which of the remaining terminals correspond to decoder lighting functions. I haven't had any luck with searching the web and the Hornby service sheets for the class 56 have no info on lighting functions.

I imagine these are very similar to the decoders found in the Bachmann US Soundvalue locos?
