The primary benefit of upgrading to Scion xB 03-07 black LED tail lights is brighter lights with less heat. Not to mention the style factor! In addition to being stylish and brighter, theseScion led tail lights are less sensitive to vibration and harshness because they have no filaments to burn out or break. This means they are tough and can handle the roughness of everyday driving... in all conditions. Another major benefit of Scion xB LED tail lights is that they light up faster than factory brake lights, which have to heat up before they can light up. This heating up can take, as long as 200 milliseconds! In comparison a Scion light will reach full intensity in less than a millisecond. We are authorized IPCW dealers therefore our Scion LED lights are covered by a full 1 year manufacturers warranty against any defects or LED outtages.
