Supernova QR Gold Connector Set with Integrated Shrink Wrap

I recommend this product

I have just had to replace one after 9 years of use.
I take the front light off when I leave my bike parked in public. One of the crimped in wires gave up the ghost - not bad for 9 years use disconnecting and reconnecting!
The connector would be reusable except that it is crimped shut.
Supernova products are well engineered and thought out.

I recommend this product

Having experimented with various connectors for my Son/SP dynamo lighting system, I decided to get these, as they are good quality, more reliable than 2.8mm spades, and less bulky than, for example, Superseal connectors.

I recommend this product

Good connectors of the same high quality as Supernova's other products. It would benefit from some colour coding on the heat shrink to identify dynamo and rear light connections and your need to make a note of which way round the blue and red rear light connections are because once in the sleeves you can't tell. I got some blue, red and white heatshrink, which solves the problem.
