An H1 bulb is a halogen bulb that is used in the headlights and fog lights of vehicles. The bulbs are manufactured in different levels of light intensity, which is represented by the exterior colour of the bulb. Although the bulb may appear to be red, green, or blue, when installed, the bulb produces white light. Halogen bulbs produce a light intensity that is closer to natural sunlight than traditional bulbs. Replacing an H1 bulb is just as easy as replacing any other type of headlight bulb.
