Product Details

LightsOn 4-Flat C

The LightsOn 4-Flat C is a consumer trailer-light tester designed for use with small utility trailers, boat trailers or RV trailers.  The tester includes the popular 4-flat connection, allowing users to plug the device into the trailer and provide the same voltage and user inputs (e.g. Brakes, Blinkers, Flashers, etc.) as they would if they were connecting a vehicle to the trailer.  This allows for significant time savings and eliminates the need for a vehicle to be the power-supply when checking trailer lights.  The 4-Flat C uses four CR-123a batteries.  These batteries can be found at your local retailer or online when they need replacement.

Save time, fuel and prevent accidents during inspections by using the 4-Flat C. This handheld device is ideal for occasional trailer light testing and safely tests up to 5 amp circuits.

Product Features

  • Lightweight, portable, ruggedized case
  • Rubberized, comfort side grips
  • Internal replaceable fuse
  • CR-123a batteries
