Many people complain about being dazzled by other drivers HID lights. Whether coming up behind you or coming towards you. What do you all think?
Oncoming drivers are bothered by HID glare because of its harsher, blue light. Light from conventional tungsten-halogen headlights is toward the softer, red end of the spectrum. Halogens would have to produce 1.5 times as much light as HID lights do to cause the same wincing, squinting and looking away.
High-intensity-discharge (HID) headlights would take a few minutes to get to full brightness if xenon were not added to the gas sealed inside the headlights. That's how the lights have come to be known, incorrectly, as xenon headlights even though xenon isn't what produces the characteristic blue-white color.
Xenon, which ignites easier and faster than other HID gases, acts as a starter. It accelerates HID lights' start-up process, making the technology suitable for cars and trucks, where waiting a few minutes for lighting is impractical.
With xenon involved, HID lights are up to speed after 1 second, and are as ready as they'll ever be in a few seconds. Xenon is responsible for the bright flash as the headlights are turned on, and it's xenon that glows brightly temporarily until the harder-to-ignite gases are at 100 percent efficiency.
Mirrors inside the light assembly capture, amplify and direct the light; lenses aim and focus it.
