- sealed beam headlight
- A headlight lamp in which the lens, reflector, and filament are fused together to form a single unit. They are relatively inexpensive, but when one component breaks, the whole unit is replaced. Newer vehicles use the more expensive composite type with separate bulb and lens which can be replaced individually in the event of failure. Only a few types of bulbs are used in the composite headlight, but the lens differs because it is shaped to the contour of the vehicle.
