A carrier module is disclosed for supporting lights for illuminating portions of a vehicle interior, instruments such as directional compasses or the like, and controls such as switches or instrument adjustment units. The carrier modules may be mounted in housings on the vehicle interior. Each module preferably includes a rigid body or support and a pair of spaced mounting projections thereon for removably mounting the carrier module in a housing or other support. One of the mounting projections is resilient. An opening is provided in the body adjacent the resilient projection to allow insertion of a tool for releasing the module from the housing or support.
