Increase your safety and visibility in any weather with these H4 LED headlight/fog light bulbs. The dual-beam LED headlight bulbs emit 4,500 lumens of cool white or yellow light per set (2,250 lumens each). Yellow light cuts through fog and improves visibility in the rain. Switch on high beams for white; yellow light is used for low beams. These bulbs have integrated heat sinks instead of short-lived fans or bulky braided heat sinks. This allows for increased longevity and easier installation in tight spaces. The LED bulbs last 13 times longer than halogen bulbs and 3 times longer than HID bulbs. LED arrays in each bulb are designed to mimic the filament in halogen bulbs—creating a closely matched beam style. These waterproof, CAN Bus compatible bulbs operate on 9-32 VDC. This long-lasting kit includes 2 H4 LED headlight bulbs. Price per kit.
