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. Our LED replacement dome lamp bulb fits all 2013 BRZ and FR-S.
Install note: Unlike regular bulbs, LED bulbs have electrical polarity, so if it doesn't light up the first time, take it out and install it the other way.
Install note 2: Use a thin flat-headed screwdriver or plastic panel tool to pry the lens free. It's got little slots for that purpose on the front edge.
