Product Overview
Headlights that stay dark with good bulbs, fuse, ground, and charging voltage may have an open switch. If the lights flicker when the knob is moved or the switch body is heat-damaged, this is the service part to compare.
The switch controls the lighting circuit on selected Simplicity-built machines. Match the terminal count and orientation, panel opening, actuator shape, bezel, and circuit rating because brand names were shared across several electrical layouts.

Frequently Asked Questions
Q: Can weak charging voltage make good headlights dim? A: Yes. Check alternator output, grounds, and wiring voltage drop before blaming the switch.
Q: Will this fit every Snapper tractor? A: No. Snapper used several suppliers and switch styles; the original number and terminals must match.
Q: How do I confirm this is the correct part? A: Match 1703799SM, terminal count and pattern, panel cutout, actuator, bezel, retention method, and wiring diagram.
Q: Is this supplied by the original equipment manufacturer? A: No. This is a new aftermarket item. Brand, model, and part numbers are used only to identify compatible applications.
