What does 'constant-current circuitry' mean?

Standard bulbs can flicker or fail because of voltage fluctuations in your car's electrical system. Constant-current circuitry regulates the voltage to the bulb, which keeps the light steady and extends its lifespan. This is a feature usually found in higher-end LED bulbs.

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

The Diode Dynamics 194 HP5 LED bulb puts out 92 lumens of light. That's about triple the light output of a standard 5W 194 or 168 bulb. If you want something less bright, Diode Dynamics also makes the HP3.

What is the warranty on this bulb?

Diode Dynamics backs this bulb with a three-year replacement warranty. If the bulb fails due to a manufacturing defect within that time, they'll replace it. Just keep your proof of purchase.
