Topic: Sparto Tail light wiring

[Schuyler]

I want to put on one of these sparto style tail light assemblies on my bike.  As I was looking at them online, I noticed each one I saw had two wires.  Since the factory light has three, I want to ask how to wire it before I buy something I can't use!

In the stock light: green is ground, one is a running light, and one is a brake light.

I assume a two wire set up would be a ground and a.....

how do I hook up both the brake light and running light?

I bought one awhile back and I believe the two wires are tail light and brake light.  The ground goes through the body of the tail light and to the chassis.

That would be my assumption as well, since I've discovered that modern turn-signals work the same way.

That is correct.
