Replace your unsightly "egg yolk" orange turn signal bulbs with tasteful LED bulbs. They're white when off, and light up orange. Our kit includes four LED bulbs (one for each corner of the car) and a special blinker module that prevents the lights from flashing extra-fast. Fits all Subaru BRZ and Scion FR-S. Install notes: If the bulb doesn't light up the first time, make sure it is fully seated in the socket. If it still doesn't light up, remove it and re-install it flipped the other way. One line of three LEDs on each bulb will not light up. That's not a defect. It has to do with dual-filament circuits, which this circuit is not. The blinker module is under the dash, mounted to the steering column. Turn on the hazard lights and listen for the clicking to find it. The old blinker module is a little difficult to remove. It clips in to the car using the clip pictured below. We were able to free it up using a small flat-bladed screwdriver, but it would be simpler just to leave it in place and zip-tie the new one to secure it.
