LEDs light up instantly and have a cooler color temperature than regular bulbs -- closer to the color of sunlight than standard bulbs, so the light is easier for the human eye to see. (See the picture above -- the stock bulb is on the left, the LED on the right.) Fits most 2002+ Subaru models, with some exceptions; see below. One-year replacement warranty. Set of two bulbs.
Install note: Unlike regular bulbs, LED bulbs have electrical polarity, so if they don't light up the first time, take them out and install them the other way. Also, make sure the wire leads are in contact with the bulb socket.
Fits most late-model Subarus, but will NOT fit 2008-2014 Impreza/WRX/STI hatch. (The housing is too small to clear the LED bulb.)
