Switch Cluster. Light, Indicator, Horn etc

Sence it has no speed control you could use it with and voltage you want, It is just switchs I would go for it if you like the set-up. Might even thread the wires thru the handle bars and make it real clean.

its just switches is exactly right you can use any voltage lights you want these are grounding switches so you would run a primary positive voltage in parallel just meaning a shared positive from the battery source then connect the grounds of the lights to the switch cluster and the switch cluster should have a master ground. you can do it the opposite if you want but i would rather float the ground then run the power thru the switch.

There is my two cents
