The Concept series LED performance bulbs have both a sleek look and provide improved visibility for safer driving at night. With a combined output of 6,000 lumens these bulbs routinely outperform halogen bulbs and most ordinary LED bulbs in the market. The patented, integrated heat sink design is a breakthrough in headlight and fog light conversions and brings a real plug & play experience to users. Converting to LED is as easy as changing the stock bulb.
