How much brighter are these than stock bulbs?

The HP24 puts out 410 lumens, which is about twice the light output of your factory bulb. This makes your turn signals more visible, especially in bright conditions.

Will these bulbs flicker or fail quickly?

No, these bulbs are built with constant-current circuitry and transient suppression. This design helps them last for years without flickering or premature failure. Diode Dynamics backs them with a three-year replacement warranty.

Do I need any special tools or skills to install these?

No, the HP24 bulbs are designed for plug-and-play installation. Simply remove your factory bulb and plug the HP24 into the socket. The non-polar design means you don't have to worry about getting the polarity right.
