It usually comes down to the science inside the bulb. We build these things to pack a huge amount of light into a tiny space, because when you&rsquo;re driving down a dark highway, seeing what&rsquo;s in front of you is the only thing that actually matters.</p> <h2 id="how-they-actually-work-and-why-they-dont-just-burn-out">How they actually work (and why they don&rsquo;t just burn out)</h2> <p>In a basic light bulb, the tungsten filament slowly evaporates and sticks to the glass. That&rsquo;s why old bulbs get that cloudy, dark look before they pop. To stop that, we fill the bulb with halogen gas—usually iodine or bromine. It triggers a little bit of chemistry that pushes that evaporated tungsten right back onto the filament. The result? A hotter glow and a lens that stays clear. But there&rsquo;s a catch. This process gets<strong>insanely hot</strong>. We have to use quartz glass because regular glass would just melt. Since these things run so hot, make sure your headlight housing has a bit of breathing room. If the heat can&rsquo;t escape, your seals will fail way sooner than they should.</p>
