This diffuser comes with a real working LED 3rd brake light that will work with your brake lights. The K Style diffusers are made using our same genuine 2x2 carbon fiber fabric as our other M3/M4 parts. Each piece is clear coated for that brilliant shine and to help protect it from harsh road conditions. For any questions or concerns please email us at sales@horizonmotorsport.com or contact us via the contact form.
