This electronic lap counter can easily be connected as a track part to your own Carrera Go race track. It comes standard with 1 extra track (same size as the round counter) so you don't get any difference in your track.

It works on 3x AA batteries (not included) or a Micro USB-B 5V connection (not included). It is easy to set up for laps and time trajectories. It counts up to 999 rounds in total. The start light goes off, just like in F1, and it gives a signal at the start and finish. The LED display ensures that it is easy to read.
