What is the term for a lamp housing, bulb, and lens that are separate components?

The term that best describes a lamp housing, bulb, and lens as separate components is known as a composite lamp. This terminology is used in the automotive industry to refer to the assembly style where each of these parts can be independently replaced or serviced, which allows for greater flexibility in maintenance and repair.

Composite lamps can be advantageous because they can reduce costs in the long run, allowing for easier replacement of individual components rather than the entire assembly. This modular approach is particularly useful in situations where only one part of the lamp may fail, reducing waste and allowing for more efficient repairs.

The other terms provided refer to different configurations or styles of lamp assemblies. An integrated lamp typically combines all components into a single unit, making it less flexible for repairs. A modular lamp often bridges the concepts of composite and integrated design but may refer to a specific type of assembly that may not clearly define the separateness of components as composite does. A universal lamp generally refers to a design that fits multiple vehicle types but does not specifically convey the aspect of separate components.
