What if the bulb flickers or doesn't light up?

These LED boards are polarity-sensitive. If the bulb doesn't light up, remove it, rotate it 180 degrees, and re-install. This should solve the issue.

How do I install the SMD12 LED board?

Installation is straightforward: remove your factory bulb and plug in the SMD12 with the included adapters. If you prefer, you can mount the SMD12 inside the factory housing using the 3M adhesive on the back of the board.

What is the warranty on the Diode Dynamics SMD12 LED board?
