What Causes the Rear Tail Lights of a Car to Stay On?
1 Answers
If the tail lights of a car remain illuminated, possible causes include the brake pad return spring not retracting, a drop in the fluid level in the brake fluid reservoir, a fault in the tail light circuit, damage to the brake light switch, or the handbrake not being released. If you notice that only one side of the tail light is on, there's no need to panic—this is the vehicle's parking light feature. Additional information: 1. Vehicle parking light feature: The purpose of the vehicle's parking light feature is to warn passing vehicles at night. Generally, this hidden function is activated after parking and turning off the engine by switching the turn signal to the side where the light needs to be illuminated. If the turn signal lever is accidentally bumped after turning off the engine, this feature might be unintentionally activated. 2. Car tail lights: Car tail lights include turn signals, brake lights, position lights, rear fog lights, reverse lights, and parking lights. Turn signals and brake lights are symmetrical, with one on each side. Considering the wavelength and penetration of light, they typically come in three colors: yellow, red, and white. White light is used for better visibility, such as in reverse lights and license plate information lights. Turn signals use more noticeable colors like yellow or red, serving an alerting and warning function.
