Where can these bulbs be installed?

These 39mm HP6 LED bulbs are direct replacements for any 39mm-size bulb, commonly found in door lights, dome lights, and trunk lights in many vehicles. They upgrade the factory yellowish incandescent bulb to a more modern LED appearance while providing more light output.

How bright are these bulbs?

The HP6 LED provides 140 lumens of measured output, which is far more light output than your original 39mm-sized bulb. Diode Dynamics tests the true output in-house and provides real numbers to compare.

What kind of warranty do these bulbs have?

These bulbs are well-built with constant-current circuitry and transient suppression, so they'll last for years, not months, with no flickering or failure. Like every Diode Dynamics product, they're backed by a three-year replacement warranty.
