Abstract: A trailer light connection system includes T-shape connectors principally for truck lighting systems respectively having three terminals including a modularized tap plug, split wire connectors principally for automobile lighting systems respectively including a modularized plug and trailer wiring harnesses respectively used with either the T-shape connector or the split wire connector and having a modularized plug interconnecting therewith. By standardizing the system components and modularizing the plug connections, the trailer lighting system of the present invention reduces the number of stock keeping units required while simplifying system installation.

Abstract: A reflecting lighted level (10) for facilitating leveling of an object, the reflecting lighted level (10) broadly comprising a generally frustoconically-shaped vial (12) having first and second exterior surfaces (22,24) and an internal angled reflecting surface (26); a light source (14) for emitting light; a light tube (16) for focusing or concentrating the emitted light towards the vial (12); a base (18) for supporting the vial (12); and a power source (20) for powering the light source (14). The internal angled reflecting surface (26) within the vial (12) is positioned at a generally 45° angle for reflecting light. The light source (14), a light emitting diode (“LED”), is centrally positioned relative to the vial (12). The light tube (16) is positioned proximate to the first exterior surface (22) of the vial (12), such that the light tube (16) is positioned between the light source (14) and the vial (12). The light source (14) is then partially positioned within the light tube (14). The light emitted by the light source (14) is transmitted through the light tube (16) and exits the light tube (16) in a concentrated beam. The beam of light is then incident on the first exterior surface (22) of the vial (12). If the level (10) is level, the beam of light reflects off of the internal angled reflecting surface (26) at a generally 90° angle and exits the second exterior surface (24) of the vial (12) in a generally concentrated beam so that a user of the level (10) may determine from a distance whether the level (10) is level. If the level (10) is unlevel, the concentrated beam of light incident on the first exterior surface (22) of the vial (12) is diffused throughout the vial (12), and the user sees little or no light, thus recognizing that the level (10) is unlevel.
