If I remember correctly when I installed my rear spoiler.....I played around with the idea of removing my third brake light. Anyways, to answer your question.....the whole lens/light assembly just prys (pops) out. You have to use a small, flat head screw driver to get between the lens and your truck's sheet metal. Be sure to use a cloth around the head of the screwdriver so to not scratch your paint job. Hope this helped.
