My original plan was to go for a diamond cut tri-bar lens and reflector with a H4 quartz lamp.
However, that was when I was building an ES2 with a Magneto.
With the Commando engine, i am 100% reliant on the battery and charging system, so I will be using LED lighting throughout.
So I have gone for a JW Speaker LED unit

I got this from the guys at Mobile Centre
https://www.mobilecentre.co.uk who were very intrigues about what I planned to use it for!!!
These are well made, low profile and give the best spread of light - they also have DOT and ECE approval.
I was very impressed with the quality of light in the demonstrations i saw, plus blown away by how little power they draw vs the amount of light they put out!
It looks a little Mad Max compared to the classic look of the tri-bar, but hopefully i'll get away with it!
I am certainly very pleased with the quality!
