Depending on the year and model, the third brake light on your Acura vehicle is located on the trunk lid, above the rear window frame or mounted on the deck just inside the rear window. It is a very important component for your safety, but if the brake light goes out, you can easily replace the bulb in a matter of minutes. The third brake light uses a type-7440 bulb which can be purchased at most automotive parts stores. Be sure to always have your Acura's lights in working order since all states have laws against driving with faulty brake lights.
Lift up the trunk lid and locate the brake light assembly at the center of the lid.
Use a flat-head screwdriver to pry off the plastic covering from the third brake light assembly.
Unscrew the bulb and remove it from the assembly.
Use a clean cloth to place the new bulb in the assembly and screw it to secure it.
Reattach the plastic covering and close the trunk lid.
