The Truck-Lite 4x6 Rectangular LED headlight system is a drop-in replacement for 1A1 and 2A1 sealed beams in most applications. The LED system provides longer life, better lumen maintenance and improved color, according to the company. A multi-volt (9-33V) design ensures that the headlight system works with any vehicle that utilizes industry standard 4" by 6" cutouts. When properly mounted, the headlights exceed FMVSS-108 and CMVSS-108 DOT requirements for both low and high beam performance.
