GMC Sierra Third Brake Lights

Customizing your GMC Sierra’s lights gives your truck some highly visible individuality, since it’s hard to overlook a non-standard light – and 1999-2018 third brake lights are no exception. Smoked lenses that turn the light of the internal LEDs into a mysterious glow and which look dark and stealthy when not in use, or clear lenses that let the clean white light of the LED elements blaze out strongly, give your truck’s third brake light a very different look from the stock equivalent. These lights are, of course, designed to meet all standard specifications for this kind of light and are 100% street legal, meeting all the requirements of federal safety regulations. If you want to dress up your Sierra’s high-level brake lamp even more, AmericanTrucks also carries 1999-2018 third brake light covers that give you an easy to install chrome trim piece that adds a gleaming border to the light.
