Truck-Lite's 4x6-inch rectangular LED headlight system is a drop-in replacement for 1A1 and 2A1 sealed beams in most applications. The system is a follow up to the 7-inch round and 5x7-inch headlights.

The system will offer a beam pattern with improved width and longer reach in a build that is designed to be lightweight.  The LED lighting provides several improvements over alternatives including longer life, better lumen maintenance and improved color.

A 9-33v multi-volt design ensures that the 4x6 LED headlight system works with any vehicle that uses industry standard 4x6-inch cutouts including buses, off-road vehicles and medium-duty trucks. With proper mounting, the headlights exceed FMVSS-108 and CMVSS-108 DOT requirements for both low and high beam performance.
