You dont need to purchase replacement bulbs, and keep a stock of them. You wont need to use the valuable time of your maintenance staff. Less downtime for your vehicles means more revenue-producing hours per vehicle. LEDs are unaffected by the on-off cycling. Their brightness doesnt diminish over time. LEDs can function over a wider range of temperatures, from desert conditions to frigid weather. LEDs last longer because they are unaffected by vibration. Incandescent bulbs contain a small filament that is vulnerable to the shock experienced by vehicles as they travel LEDs dont have filaments. LEDs have no bulb that can work loose they are solid-state. LEDs produce less heat. LEDs are safer. A buildup of heat is undesirable, since the potential exists to cause fires. LEDs run far cooler. The heated glass of conventional bulbs is vulnerable to splash and more likely to fail prematurely. LEDs are more efficient. Less battery drain. Up to 90% of the power used in an incandescent bulb is converted into wasted heat energy. For the amount of light emitted, LEDs draw fewer watts from your batteries. LEDs are not susceptible to the corrosion that may occur in bulb bases and sockets. Visit Littelfuse.com for the most up-to-date product information.
