The standard Triumph light bar, as far as I know, can only operate from the toggle switch on the back of the left light.
The option of a switch on the bar was not offered.
I would like the light bar to operate like this:
1. Come on with main beam (for flashing and night use),
2. Come on using a bar operated switch for use without main beam.
I'm looking at getting mine done when I come back from AZ.
I'm no electrician so it'll have to go to a shop.,
Ride safe
