The P13W PNP Series LUX LED Replacement Bulbs are a practical and efficient lighting solution for your vehicle. 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 sold as a pair and can increase driving distances 2-3 times over halogen bulbs. They are plug and play, with the same size as the halogen bulbs they replace. For newer vehicles, an in-line Canbus decoder may be needed for proper interface. Replacing most P13W lights, these LED bulbs are a reliable and high-power option.
