LED stands for "Light-emitting-diode", it is a semiconductor device with two terminals, typically it only allows current to flow in one direction, therefore they are polarity specific. Unlike incandescent bulbs that are used on most vehicles, LED's do not have a filament that produces both heat and light, instead it has electrons that flow to create photons, which generate very low heat. LED's use much less energy to create an increased amount of brightness compared to incandescent lights, and last longer.
This Courtesy Door Light Kit for 2000-2004 Tundra is a direct replacement for your OE incandescent bulbs. OE incandescent bulbs are usually orange/yellow in color, generates excess amount of heat when turned on for an extended period of light, versus its LED counter part that has a modern white color, produces minimal amount of heat and draws less power. Not only do LED's look great compared to the OE incandescent, if for some reason you left your door opened, the OE incandescent bulbs have a greater chance to melt your courtesy door light lens and drain your battery compared to the LED's.
This LED Interior kit lights up the car in a stylish and efficient manner, it will also give your interior that modern luxury feel.
LED are polarity specific, if it does not turn on after install, please reverse the polarity by turning the bulb around.
