“LEDs themselves are bright, and fit in small LEGO spaces as described. However, the wires are far too short and not discretely coloured - if using a JST connector, do we need to have red/black coloured wires?”
Ahoy! Thanks for the feedback - we definitely agree with you on the red/black cables, we actually asked for black cables on these. Hopefully we'll be able to get this fixed on future batches!
