Another alternative for headlights is LED. This new technology provides excellent illumination in a 7-inch round lamp for forward-lighting, 12-volt applications. LEDs offer extended life and energy efficiency. They have a bright and crisp white light output, and offer long service life and great dependability. The LED headlamps feature solid-state circuit board assemblies for shock and vibration resistance. They have hard-coated polycarbonate lenses that offer 30 times the impact resistance of glass. The kit costs $578 and is warrantied for the life of your car by Mustang Project.
