How much brighter is this compared to a stock bulb?

The HP5 puts out 92 lumens, about triple the light of a standard 5W 194 or 168 bulb. If that's too much, Diode Dynamics makes a slightly dimmer version called the HP3.

What does 'constant-current circuitry' mean?

Standard bulbs can flicker or fail due to voltage fluctuations in your car's electrical system. Constant-current circuitry regulates the current to the LED, which helps prevent flickering and extends the bulb's lifespan.

How long is the warranty?

Diode Dynamics backs this bulb with a three-year replacement warranty. If you have any issues, contact them directly for assistance.
