How bright are these compared to stock?

The HP11 puts out 310 lumens per bulb, which is more total light output than your factory bulb. Diode Dynamics tests the true output in-house and provides real numbers to compare.

Will these bulbs flicker or fail quickly?

These bulbs use constant-current circuitry along with transient suppression. This design should last for years, not months, without flickering or failure. They're also backed by a three-year replacement warranty.

What size are these bulbs?

These are designed as direct-fit replacements for 7440 and 7443-sized bulbs. Installation is plug-and-play simple: remove the factory bulb and plug this one in.
