Abstract: The present invention relates to an adjustable-length removably-mountable integral holder system having an elongate holder body which includes a first entry located at its forward end and a second opening located at its rear end. One or both ends of the body may possess means for mounting or connecting one or more auxiliary lighting units. Each end of the housing includes means for engaging a structural member. The length of the housing can be axially adjusted to allow removable mounting of the system between the structural members of a vehicle and to accommodate different mounting spaces. The elongate housing includes at least two sections which are axially extendable with respect to one another and further can be spring biased to allow compression of the spring when one end of the housing is moved toward the other for producing a force of securement when the housing is positioned in a space between two structural members which space is smaller than the overall length of the housing in an uncompressed state.

Abstract: The present invention relates to a removably-mountable integral lighting system having an elongate battery housing which includes a first lighting assembly mounted to its forward end, and a second lighting assembly mounted to its rear end. Each end of the housing includes means for engaging a structural member. The length of the housing can be axially adjusted to allow removable mounting of the system between the structural members of a vehicle and to accommodate mounting spaces of different sizes. The elongate housing includes at least two sections which are axially movable with respect to one another and are spring biased to allow compression of the spring when one end of the housing is moved toward the other for producing a force of securement when the housing is positioned in a space between two structural members which space is smaller than the overall length of the housing in an uncompressed state.
