Third brake lights are relatively new in the automotive world. For many years vehicles came standard with only two dim taillights, but in the 1970s a psychologist developed the idea of a high-mounted center brake light that would be better at getting the driver's attention. Now third brake lights are a legal requirement on all new vehicles. In addition to their functionality, it is possible to use GMC Sierra third brake lights in custom applications.
