Upgrade your fog lights with these ROYLUX LED bulbs and see the road like never before. They're a direct replacement for 9004/HB1 bulbs and put out a massive 24,000 lumens – that's 600% brighter than old halogen bulbs! The light is a clean, white 6000K color that cuts through fog, rain, and snow much better than yellowish halogens. They're built to last, with a claimed lifespan of over 50,000 hours. They feature a built-in turbo cooling fan and an aluminum heat sink to prevent overheating and keep performance stable. The best part for modern cars? They're 99% CANBUS ready, so you likely won't get error messages on your dashboard – just plug them in and go. PLEASE NOTE: Always double-check the bulb size on your old bulb or in your owner's manual before buying, even if Amazon says it fits. An easy install for massively improved visibility and safety.
