Re: Road train lighting
might have got that bit wrong - you'll figure it out if you look at the way they're hooked up....either way, I would suggest 5V minimum with protective resistors. I think the MFU actually provides 6V...

Re: Scania my first build

Re: Tamiya trailer light set
if you want to add extra LEDs in parallel, I would suggest buying 4x LEDs and replace the original Tamiya ones too. The reason being that unless you can find an identical spec (and I don't know what...
