Having already soldered the LEDs onto the board it was time to connect them to the resistor board and the voltage regulators.
Once they were all connected together it was time to fit them into the lenses. This wasn't how I was going to mount them originally but they look ok and it made life a lot easier!
And finally, here is one of the completed clusters. They are still a little rough around the edges and I'm not sure that the brake/tail light is bright enough. This is mainly down to the extremly dark lense, another we have is much lighter and the LEDs shine through very brightly so I will be trying to source a pair of these lighter lenses.
