Light-emitting diodes, or LED's as they are better known, are a highly advanced lighting technology that produce a high lumen output while using a fraction of the normal wattage that bulbs require. This makes LED bulbs the best lighting technology on the market today. LED bulbs replace your stock/standard halogen bulbs, providing an extremely bright light with a cool color. Our LED bulbs come available in white, red and blue. Some vehicles require resistors when converting your stock halogen bulbs over to LED light bulbs.
