First time I've seen that arrangement Jay
It worked really well.
Switch was £3 - Halfords
Wire was £5 for 25m from CEF Electricals (didn’t use it all of course)
Lightbar was £10 from Amazon
Steel was free from fabricators (a bit of scrap)
The fuse box was £12 from Amazon
A few connectors and a basic drawing on paper of what I wanted. It worked a treat.
Sold the bike but kept the light bar, it’s now on the pickup truck.
Can have a look for my old plans if anyone is interested and do out a more detailed diagram.
