Abstract
Abstract An improved housing for an electrically operated vehicle backup alarm for mounting on a vehicle bumper or other structural component in preformed, standard size receptacles. A tubular body fabricated of plastic or nylon composite includes internal mounting lugs for removeably mounting modular electronic components and sound transducer. A removable rear cover and epoxy potting material seals the alarm components against dirt and moisture intrusion. Resilient mounting lugs or fingers external to the housing allow the housing to be mounted within preformed mounting receptacles. The mounting lugs or fingers are deformed slightly when the housing is inserted into the mounting receptacle and snapped into engagement with the edges of the mounting receptacle securely holding the housing in place within the mounting receptacle.
