7-inch round replacement lamp
A five-LED 7-inch headlight with combined high/low operation and an aluminium reflector.
Five-LED construction
Manufacturer-rated output: 1,020 lumens low / 1,600 lumens high.
Match the beam function
High and low beam. Choose the lamp for the circuit and position being replaced.
One lamp per order
This listing supplies one headlight, not a vehicle set. Confirm the quantity required for your installation.
Fitment & selection
Start with the lamp already installed
Compare the existing lamp marking, retaining hardware, rear clearance and circuit functions. A nominal size or model name alone does not confirm compatibility.
Match the ground, low-beam and high-beam circuits to the exact pinout diagram before installation. Verify the mounting ring and rear housing clearance.
Manufacturer-listed truck applications
These application entries still require the matching original lamp arrangement. Check any modified housings or wiring separately.
