Note: Since the LED bulbs have lower wattage than stock 55W halogen bulbs, you might need to add load resistors or decoders to ensure proper function when installing on some newer cars or European vehicles. Installation: When installing this bulb, please make sure to turn off the car, and key out. All of our LED bulbs are designed for easy DIY installation & direct replacement. If LED bulb doesn't light up after installation, please simply re-insert it oppositely (because LED bulb has polarity like a battery).
