How much brighter is this bulb compared to stock?

The HP5 puts out 92 lumens, about triple the light of your original 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?

Constant-current circuitry helps the bulb last longer. Cheaper LED bulbs can flicker or fail quickly, but this design keeps the current consistent to prevent that.

What if I want a different color?

Besides pure white, the 194 HP5 is available in cool white (6000K), warm white (3000K), natural white (4000K), blue, red, and amber.
