When installing the fender mounted taillight housing, the first step is to open the access door of the trunk located, and disconnect the electrical connection and the fasteners connecting the housing to the car. After separating, take out the taillight housing. In case LED lighting is unavailable on the vehicle, the inside part will have 2 replaceable bulbs; the bulb housing could be removed by pushing in on the tabs and then twisting in a counterclockwise direction to remove the bulbs. To install, reverse the way of removing. In the case of trunk mounted taillight housing, one should remove the cover on the trim to the trunk and loosely open the back of the housing. To remove the taillight housing, remove the trim access panel, disconnect the electrical connection, and then remove the mounting fasteners. Carmobiles lacking LED tail lamps will have a replaceable bulb housing, press the superior tabs inwards and the bulb housing will be separated; in it will be three independent replaceable bulbs. The removal is inverted into installation.
