The FlexMod Electronic Timer for Lighting prevents the internal lights inside a trailer from being left on and draining the battery. Vehicle operator operates a momentary switch which turns lights on, allowing safe operation inside the cargo compartment. After 20 minutes the FlexMod flashes the lights and gives the operator increasingly urgent warnings to either exit the cargo compartment or reactivate the timer before the lights go out.

Perfect for use on delivery vehicles, utility vehicles, trailers or straight trucks.
