I used a little of the wiring included with the optronic lights, but most of the wiring I used was not.

I used soldering, heat shrink tubing, followed by liquid electrical tape on most of the connections, and then wrapped the wires together with black electrical tape.

However, I did use crimping connections close to the lights. This was so I could easily take the lighting system on and off the bike. I used liquid electrical tape on each of the crimped connections too.

I didn't use connections included with the lights, substituting my own instead. One thing you should know, the optronic's wires are not copper and are very "slippery". I had a helluva time attaching solder or crimping connections onto them.
