The term "reverse light" refers to a light mechanism that is typically located at the rear of a vehicle and specifically designed to provide illumination when the vehicle is put into reverse gear. These lights emit a bright white light that serves the purpose of enhancing visibility for the driver, as well as for other road users, particularly during nighttime or in low-light conditions.
The purpose of reverse lights is to alert and inform those around the vehicle that it is backing up. This warning helps to prevent accidents and allows pedestrians and other drivers to take necessary precautionary actions. Additionally, these lights assist the driver in maneuvering the vehicle in reverse by providing better visibility to obstacles or objects behind the vehicle that may not be visible by using only the rearview mirrors.
Reverse lights are typically activated automatically when the driver shifts the gear into reverse, although some vehicles might require manual activation. They are usually positioned either on either side, or in the center, of the vehicle's rear bumper or taillight cluster, ensuring they are visible from various angles.
Most modern vehicles employ light-emitting diodes (LEDs) for their reverse lights due to their low energy consumption, longer operational life, and quicker response time. Different jurisdictions might have specific regulations regarding the use, color, or brightness of reverse lights in order to maintain standardized road safety.
The word "reverse" originates from the Latin term "reversus", which is the past participle of "revertere", meaning "to turn back". It entered the English language in the late 14th century with the sense of "to turn back or go backward".

When combined, the term "reverse light" refers to a light at the rear of a vehicle that illuminates when the driver is reversing or moving the vehicle in reverse gear.
