Where are these bulbs typically used?

These 28mm festoon bulbs are commonly found in vanity mirror lights in many vehicles. Check your vehicle's bulb size before ordering to ensure proper fitment. You can consult your owner's manual or a vehicle-specific online forum.

How much brighter are these compared to the original bulb?

The SMF2 LED bulb provides about double the total light compared to your original 28mm-sized bulb. It has a measured output of 24 lumens. This will give your vehicle a more modern and brighter look.

What if the bulb fails?

Diode Dynamics backs these SMF2 LED bulbs with a three-year replacement warranty. If you experience any issues with the bulbs within that time, contact Diode Dynamics directly for assistance with a replacement.
