Pilot LED technology provides a clean, bright, and long-lasting light for vehicle applications. The numbering designations follow the established bulb identification system and assure you will find the proper LED replacement bulb for your application. Pilot LED bulbs produce more light per watt than traditional incandescent bulbs, and less heat, making them perfect for enhanced visibility, safety and creative lighting needs. LED bulbs are much more economical and efficient, lasting up to 50,000 hours, which means these may be the last bulbs youll ever need for your vehicle! All Pilot LED bulbs allow for easy plug-and-play installation. Built-in CAN bus technology mitigates bulb out / error messages. Note: As LED bulbs draw much less wattage than conventional bulbs, some vehicles may still require a resistor (Pilot part# IL-LDRS-A) to function properly.
