Peterson Manufacturing Clear 4 Inch Back-Up Light features a sealed, 4 inch round clear light that functions as back-up or utility light. It features an extra wide, spin-welded, tongue-and-groove lens lip and waterproof seal. The high performance, copper alloy conductors eliminate the possibility of wire failure. The state-of-the-art bulb design features three supports for the minor filament and two supports for the major filament providing long bulb life. The wedge-base socket prevents premature bulb failure. It requires a mounting grommet and a 2-wire plug. The 12-volt lamps have been designed with a dual filament, 2.10 amp and a 32 cp bulb. The low light function is for accessory use only.
