LEDs are often used in fog lights because they produce a bright, concentrated beam of light that can penetrate through the dense fog. Some advantages of using LEDs in fog lights include:
-LEDs are more energy efficient than traditional incandescent bulbs and will last longer.
-They emit very little heat, so there is no risk of melting any ice or snow that may be on your car.
-Their small size allows for a more compact design, which is ideal for space-saving fog lights.
