HID Headlights - H1 bulbs, or HID Headlights, are normally 55W, which is standard for most car's high beams. Factory H1 bulbs are clear in color, while after-market, non-factory, bulbs which claim to be whiter and brighter tend to have a blue tint on the glass part of the bulb. Even though bulbs like the HID headlights are so much brighter and can enhance the look of a vehicle as well as improve road visibility which will make it safer to drive, it is still important to be considerate of other drivers. If your headlights are too bright, or if your headlights are aimed too high in a way that they shine into oncoming driver's eyes, this is not only inconsiderate; it is also dangerous. Extremely bright lights are a distraction to other drivers. This can cause a car accident, and there is also the possibility for damaging the eyes of another driver. True High-intensity discharge bulbs are are much brighter, made of a completely different material, and are far more powerful. They are also more expensive since they are much higher quality, have a better performance, and a longer lifespan. HID bulbs last up to ten years. HID, H1 bulbs last the typical lifespan of 1-2 years. HID bulbs require a special conversion box because there is an extremely high voltage, it is 25,000V as opposed to the traditional 12V vehicle voltage, they can ruin a car's electrical system. HID's are safe as long as they have this special conversion box and proper installation.
