Q1: Why switch to LED?

Q4: No page lights up? Both sides flicker, flash or work unevenly.
A: Check the headlight fuses and then the ballast plugs to ensure proper installation. If this doesn't work, there may be a voltage problem with the vehicle. You probably just need a relay or a capacitor.
Q5: When do you need the Warning Canceller?
A: Some vehicles with complex internal computers (such as Audi, BMW, Jaguar, Mercedes, etc.) may report dashboard errors or flickering headlights. The Warning Canceller fixes the dashboard warning and flickering effect.
Bulb Out Dashboard Error: On some vehicles, the dashboard reports as if a headlight bulb is missing or burned out. This does not affect the function of the headlights, but the light on the dashboard lights up. The Warning Canceller fixes the problem.
Flickering Problem: This occurs when your vehicle does not detect the newly installed headlights. When the headlights are turned on, the vehicle computer does not understand the signal from the headlights and therefore thinks that they are still off. This triggers the headlight flickering effect. The Warning Canceller solves this problem.
Q6: WARNING ABOUT POLARITY
A: Unlike halogen lamps, LEDs are polarity sensitive.
BEFORE you begin installing your LED kit, check the polarity on your vehicle by simply plugging the LED bulb into your vehicle socket.
- When your light turns on, please install both lamps in your vehicle.
- If your light does NOT turn on, unplug the bulb and flip the socket to reverse the polarity (this will not damage your electrical system in any way). Once you have made sure the LED bulb is on, please proceed to install both bulbs in your vehicle.
Note: There is no convention when it comes to polarity. Different car manufacturers have different polarity settings, even within the car model the polarity setting on your low beam and high beam may be different.
