Product Overview
The switch contains separate run and accessory/light switching functions. The normal positions are OFF, RUN, and RUN with lights/accessories, allowing the cart to operate while also controlling the factory-style lighting circuit.

Frequently Asked Questions
Q: Does the second ON position power the lights?
A: Yes. On this switch family, one ON position runs the cart and the next position powers the light/accessory circuit while allowing operation.
Q: Will it fit an RXV?
A: Replacement catalogs specifically warn that 2008-up RXV models use a different switch; verify before ordering.
Verify 4-terminal configuration and original switch number, especially on RXV-era carts.
