This was our first Light My Bricks set and we are very impressed. The wires are so tiny and this looks great when fitted to the Tron Lego set. It is a shame the Lego set itself doesnt accomodate a way to make the light from the rear of the bike light up similar to how it is in the film, although it might be possible to modify this one to move the front light towards the back instead. Something we might try ourselves at some point. Great value for money and the modular design of these make it possible to plug and play with different colour lights if people wanted.
