About our F1 Series LED Bulbs
Our F1 Series LED Headlight bulbs are designed to give you more light output while maintaining a safe beam pattern for oncoming traffic. Your factory cut off line will stay at the same level but the brightness below it will shine brighter and farther down the road!
IT'S VERY IMPORTANT THAT YOU KNOW THE BULB SIZE NEEDED FOR YOUR VEHICLE BEFORE ORDERING. WE HAVE THEM LISTED IN OUR VEHICLE SEARCH OPTION BUT FOR MORE CLARIFICATION WE HAVE GIVEN YOU THIS SPECIFIC LIST FOR YOUR VEHICLE.
This Light Bulb Size Diagram is for Chevrolet Silverado and GMC Sierra 1500 Trucks. Including Years 2016, 2017 and 2018.
Every bulb we have listed for these trucks have been tested by us at FUZED LED and they are completely plug and play. No extra resistors or wiring required AND Extremely bright!
