The IntraUSA Group, Inc. is now supplying Headlamp Life Extenders to Truck-Lite Co. The innovative product significantly lengthens headlamp life by providing a soft-start to the filaments, regulating DC voltage, and eliminating voltage spikes. Trucks equipped with Headlamp Life Extenders are projected to lengthen headlamp life by as much as 60 percent. The Headlamp Life Extender controls surges and limits output voltage (input to the headlamp) to 12.8 volts, for the optimum balance of brightness and long-life.
