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.
