What if the bulb doesn't light up when I install it?

LEDs are polarity-sensitive. If the bulb doesn't light, unplug it, rotate it 180 degrees, and plug it back in. It should light right up.

What colors are available?

Besides this cool white (6000K) version, Diode Dynamics offers this bulb in warm white (3000K), pure white (5000K), and natural white (4000K). They also offer vibrant colors like blue, red, amber, and green.

How much brighter will this be than my factory bulb?

Diode Dynamics uses measured lumen figures, not calculations, so you can compare the real output. Expect a noticeable increase in brightness compared to your original incandescent bulb.
