Product Details

The Airtex 1S5643 is a direct-fit replacement backup light switch (also known as a neutral safety backup switch, reverse light switch, or back-up lamp switch) designed to restore proper reverse light operation. This switch signals the transmission's reverse gear engagement, activating the backup lamps to alert pedestrians and drivers behind the vehicle.

Key Features:

  • Direct OE-style replacement — engineered to match original equipment fit, form, and function
  • Activates backup (reverse) lights when transmission is shifted into reverse gear
  • Cross-references Standard Motor Products part number LS300
  • Manufactured by Airtex Automotive Division, a trusted supplier of engine management and electrical components
  • Plug-and-play installation — no modification required
  • Helps maintain safe reversing visibility and compliance with lighting requirements

When the original backup light switch fails, reverse lights may remain off entirely or stay on continuously, creating a safety hazard. The Airtex 1S5643 restores correct function and is a reliable, cost-effective alternative to dealership parts.
