The downside is that they are more expensive than halogens or high-intensity-discharge headlights, which typically use xenon gas. LEDs also typically don’t burn out like incandescent bulbs, though they do dim over time.īecause LEDs are smaller than bulb-type lights, they allow more design freedom with headlights and other vehicle lights. LEDs operate about 90% more efficiently than incandescent bulbs, and because they generate less heat, that helps them last much longer than other types of lights. With LEDs, an electric current passes through a semiconductor (or diode) to produce light that is brighter and generates less heat. Halogen bulbs are brighter than regular incandescent bulbs and tend to last longer. They differ from regular incandescent bulbs in that they have a dose of halogen gas instead of argon gas.
When electric current passes through the filament, it heats up and generates light. Here’s how they’re different: Halogens are incandescent lights that have a tungsten filament inside a bulb. Halogen headlights were the standard for the auto industry for years because they were cheap to manufacture and simple to replace, but now LEDs are outshining them. What’s more, a lot of people think they look cool.
LEDs appeal to automakers and consumers for several reasons: They’re brighter than halogen headlights and often cast a wider pattern, plus they use less energy, last longer and have a much whiter color than halogens, which typically are yellowish.
