What does 'constant-current circuitry' mean for this bulb?

Constant-current circuitry regulates the power flowing to the LEDs. This protects them from voltage spikes and ensures consistent brightness over the bulb's lifespan. This design choice helps the bulb last longer.

How much brighter will these be compared to my stock bulbs?

The SMF2 LED bulb produces 24 lumens of light. Diode Dynamics states this is about twice the light output of a standard 36mm bulb. This will give your vehicle a brighter, more modern look.

What is a 'festoon' bulb?

A festoon bulb is a type of automotive bulb that is cylindrical in shape with metal caps on both ends. These caps slide into the electrical contacts of the fixture. They are commonly used for interior lighting.
