New technology previously only on high-end luxury cars is now available for trucks! LEDs quickly alert other drivers of your intentions with LED bulbs that illuminate 140 times faster than conventional incandescent bulbs, which translates to a gain of 20+ feet of reaction distance.
Additional LED benefits:
LED lights have no filament, which means they are less sensitive to vibrations, and they can last up to 20,000 hours. They use only 15% of the energy required by incandescent bulbs, reducing the load placed on your truck's charging system, and less heat is emitted.
An Electronic Flasher is recommended when upgrading to LED bulbs or light assemblies. Due to the lower current draw of LED lighting, the factory flasher may cause inconsistent flash rates, no flash or indicate that a bulb is out.
