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.

Install note: The fog lamp bulbs are an unusual bulb type, and the replacement LED bulbs don't always exactly match the various tabs on the original bulbs. On some bulbs, you'll have to carve off three of the tabs per bulb to fit them -- two external tabs,and one for the electrical plug. See the photo. 

Super white color. Sold as a pair of bulbs.  Fits all 2013 BRZ and FR-S.
