What is a Tail Light?

[ElliotFitz]

Automotive tail lights include turn signals, brake lights, position lights, rear fog lights, reverse lights, and parking lights. The details are as follows: Distribution sequence: The rear fog light and reverse light are arranged with the fog light on the left and the reverse light on the right, meaning there is one fog light and one reverse light. Turn signals and brake lights are symmetrically placed, with one on each side. Tail light colors: Considering the wavelength penetration of light, they generally come in three colors: yellow, red, and white. White lights are used where better illumination is needed, such as reverse lights and license plate information lights. Turn signals use more noticeable yellow or red colors. Lights that require high visibility and warning functions also use red, such as brake lights, high-mounted stop lights, night lights, and width indicator lights.
