LED fog lights - Lamps and each lamp has 6 powerful 3030 chips. Lower power than halogen bulb, energy-saving. It can provide greater light output with much less current. LED fog lights with cold-pressed aluminum heatsink - 35% higher heat reduction. Advanced design optimizes for heat protection and consistent brightness. With efficient distance and aluminum air cooler, maximum lifespan for LED lamps is ensured. Easy installation - Compatible mounting size and non-polarity design, just Plug & Play. Carefully designed beam angle: Same as the halogen bulb's angle but superior lighting results. Since these LED fog light bulbs have lower wattage than normal halogen bulbs, when installing this item on some European cars, the car's canbus system is very sensitive and NOT COMPATIBLE with LED bulbs, so you may need to add load resistors or special wiring DECODERS (not included in this order) to avoid hyper flash or dashboard errors. Used ONLY for fog lights (not suitable for use with headlights and does not have Hi-Low headlight functions).
