+1 each Hydra and Sharps Third Brake lights, official title Center High Mount Stop Lamps (CMHSL) were started in 1986 for North American Vehicles. Excerpt from Wikipedia below.
I believe when they first came out it was just cars. FYI In states that have a vehicle safety inspection program it is an inspection item and they can fail you if it does not illuminate. Ask me how I know. I didnt fail but was told during pre inspection that it could be a failure item so I replaced it prior to the full for record inspection.
Centre High Mount Stop Lamp (CHMSL)
LED CHMSL retrofitted on a 1974 ValiantIn North America since 1986, in Australia and New Zealand since 1990, and in Europe since 1998, a central brake lamp, mounted higher than the vehicle's left and right brake lamps and called a "Centre High Mount Stop Lamp (CHMSL)", is also required. The CHMSL (pronounced /ˈtʃɪmzəl/) is also sometimes referred to as the "centre brake lamp", the "third brake light", the "eye-level brake lamp", the "safety brake lamp", or the "high-level brake lamp". The CHMSL may produce light by means of a single central filament bulb, a row or cluster of filament bulbs or LEDs, or a strip of Neon tube.
The CHMSL is intended to provide a deceleration warning to following drivers whose view of the vehicle's left and right stop lamps is blocked by interceding vehicles. It also helps to disambiguate brake vs. turn signal messages in North America, where red rear turn signals identical in appearance to stop lamps are permitted, and also can provide a redundant stop light signal in the event of a stop lamp malfunction.
The CHMSL is generally required to illuminate steadily and not permitted to flash,[56][57] though U.S. regulators granted Mercedes-Benz a temporary, limited exemption to the steady-light requirement so as to evaluate whether a flashing CHMSL provides an emergency stop signal that effectively reduces the likelihood of a crash.[58]
On passenger cars, the CHMSL may be placed above the back glass, affixed to the vehicle's interior just inside the back glass, or it may be integrated into the vehicle's deck lid or into a spoiler. Other specialised fitments are sometimes seen; the Jeep Wrangler and Land Rover Freelander have the CHMSL on a stalk fixed to the spare wheel carrier. Trucks, vans and commercial vehicles sometimes have the CHMSL mounted to the trailing edge of the vehicle's roof. The CHMSL is required by regulations worldwide to be centred laterally on the vehicle, though ECE R48 permits lateral offset of up to 15 cm if the vehicle's lateral centre is not coincident with a fixed body panel, but instead separates movable components such as doors.[15] The Renault Master van, for example, uses a laterally offset CHMSL for this reason. The height of the CHMSL is also regulated, in absolute terms and with respect to the mounting height of the vehicle's conventional left and right stop lamps.[59] Depending on the left and right lamps' height, the lower edge of the CHMSL may be just above the left and right lamps' upper edge.

Here is one more follow up to the previous excerpt.
In 1986, the United States National Highway Traffic Safety Administration and Transport Canada mandated that all new passenger cars have a CHMSL installed. A CHMSL was required on all new light trucks and vans starting in 1994. CHMSLs are so inexpensive to incorporate into a vehicle that even if the lamps prevent only a few percent of rear end collisions they remain a cost-effective safety feature.[64]
