The H11 PNP Series LUX LED Replacement Bulbs are a practical and efficient solution for upgrading your vehicle's lighting system. With a one-piece die-cast bulb body and built-in drivers, these bulbs offer superior heat dissipation and thermal conductivity. They operate within a wide voltage range of 9-32 volts and provide an ultra-high luminous output. These bulbs are designed to increase driving distances 2-3 times over halogen bulbs, making them perfect for nighttime driving. With a plug-and-play installation and the same size as the halogen bulbs they replace, these bulbs are compatible with most H11 lights. For newer vehicles, an in-line Canbus decoder may be needed for proper interface.
