Night time vehicle conspicuity to the rear is provided by the tail lights (also called "taillamps" or "tail lamps", "taillights"). These are required to produce only red light, and to be wired such that they are lit whenever the front position lamps are illuminated—including when the headlamps are on. Rear position lamps may be combined with the vehicle's stop lamps, or separate from them. In combined-function installations, the lamps produce brighter red light for the stop lamp function, and dimmer red light for the rear position lamp function. Regulations worldwide stipulate minimum intensity ratios between the bright (stop) and dim (tail) modes, so that a vehicle displaying rear position lamps will not be mistakenly interpreted as showing stop lamps, and vice versa. All of the tail lights we carry are DOT approved and meet or exceed the performance of the factory equipped tail lights on your vehicle. When it comes to tail lights you never want to compromise due to the critical nature of the part for safety reasons. You will not find tail lights that are brighter at night than our LED tail lights. We carry several styles of aftermarket tail lights including altezza, euro, black, chrome, and more. We offer standard and LED version tail lights for most modern makes and models.
