Q7: WARNING ABOUT POLARITY
Unlike halogen bulbs, LED are polarity sensitive.
BEFORE you start your LED kit installation, verify the polarity on your vehicle by simply plugging the LED bulb into your vehicle socket.
- if your light turns on, please proceed to install both bulbs onto your vehicle.
- if your light DOES NOT turn on, disconnect the bulb and flip the socket in order to reverse the polarity (this will not damage your vehicle electrical system in any way). Once you made sure the LED bulb turns on, please proceed to install both bulbs onto your vehicle.

Note: There is no convention when it comes to polarity. Different car manufactures have different polarity setup, even within the car model the polarity setup on your low beams and high beams might be different.
