They use no gas and contain no filaments. They work by passing electricity through semiconductors, which release light, explains. LED headlights, though, don’t work the same as either of these two. Xenon bulbs, aka ‘high-intensity discharge’ bulbs, lack the filament instead, they use electrical current to directly heat xenon gas. As current flows through the element, it starts to glow, releasing light and heat. Inside the bulb is a tungsten filament (the ‘heating element’) surrounded by halogen gas. Halogen headlights work like traditional incandescent bulbs, Carfax explains.

And while some advertise the former as ‘LED bulbs,’ that’s actually incorrect terminology. It’s important to note that LED headlights are distinct from halogen ones.

But trying to upgrade your lights that way isn’t always worth the hassle or expense. And since LED headlights aren’t always standard, that often means trying to fit the bulbs in halogen housings. After all, if you can’t see the oncoming danger, how can you avoid it? That’s why, to try and counter poor headlight performance, many turn to LED bulbs to brighten up the road. Even if your car’s headlights aren’t adaptive, they’re still an important car safety feature.
