LEDs appeal to automakers and consumers for several reasons: they are brighter than halogen headlights and generally cast a wider pattern, and they use less energy, last longer, and are whiter than halogens, Halogen lamps are usually yellow. What's more, a lot of people think they look cool.

　　Halogen headlights have been the standard in the automotive industry for years because they are cheap to manufacture and easy to replace, but now LEDs outshine them.

　　Since hitting the road, automotive LED lights have changed the way manufacturers and drivers understand automotive lights. While LEDs may be slightly more expensive than halogens, LEDs last longer and have a higher light intensity of up to 12,000 lumens. This quality of light enables better visibility on the road, allowing drivers to stay safer on the road.

　　First things first: If you're switching, you want to know if led lights for cars headlights are worth the money. Fortunately, a car's LED lights can last up to 20 years. This means you will rarely need to replace LED headlights compared to halogen lamps, which sometimes need to be replaced every year. The longevity of these lamps is partly due to their simple but sturdy construction. LEDs consist of a single unit that converts electricity into light, which is more efficient than halogen bulbs, which require more components and moving parts to function.

　　The LEDs have heat sinks that prevent the area through which current flows from heating up. Here's what makes sure you're looking for the best LED lights for your car: a poorly functioning radiator can do more damage to the entire car.

　　Here's how they differ: Halogen lamps are incandescent lamps with tungsten filaments inside the bulb. When current is passed through the filament, it heats up and produces light. They differ from regular incandescent bulbs in that they have a dose of halogen gas instead of argon. Halogen bulbs are brighter and last longer than regular incandescent bulbs.

　　With LEDs, current is passed through a semiconductor (or diode) to produce brighter light that produces less heat. LEDs work 90 percent more efficiently than incandescent bulbs, and because they generate less heat, this helps them last longer than other types of lights. LEDs also generally don't burn out like incandescent bulbs, although they do dim over time.

　　Because LEDs are smaller than bulb-type lamps, they offer greater design freedom for headlights and other vehicle lights. The downside is that they are more expensive than halogen or high-intensity discharge headlights that typically use xenon gas.
