2011-2016 Ford Super Duty LED Headlight Bulb Upgrade - GTR Lighting Ultra Series
Most LED headlight bulbs out there have a poor beam pattern and lack the brightness you'd expect from a high-end bulb upgrade. 
The 3rd Generation GTR Lighting Ultra Series LED Headlight Bulbs are the brightest LED headlight and fog light bulbs on the market. They have a more precise beam pattern hot spot than any others, the fit more vehicle applications better than others, and they use less wattage, and less Lumen than others but create significantly more light!
