When converting a classic vehicle from 6 volts to 12 volts, running the original 6‑volt wiper motor can cause it to operate at double speed—reducing performance and shortening the motor’s lifespan. Finding a proper 12‑volt replacement for older vehicles is often difficult, making a voltage reducer the ideal solution.

This adjustable 12v‑to‑6v voltage reducer installs easily and provides smooth, reliable operation. It not only protects vintage wiper motors but also adds the benefit of variable speed control. Detailed instructions are included, and it can also be used with other high‑load 6‑volt accessories.
