Abstract: The invention provides an auxiliary light assembly which is disposed on and secured to a predetermined portion of a motorcycle and which is operatively coupled to a source of voltage for illuminating a ground surface forward of the motorcycle being ridden with its front wheel elevated above the ground surface. A switch is operatively coupled to the light assembly for selectively supplying the voltage and terminating voltage supply. According to one embodiment, the present invention contemplates the use of a mercury switch which is mounted within the light assembly.

Abstract: A device and methods for the rapid chemiluminescence or calorimetric assay of surfaces to detect the presence of microbial or protein contamination is disclosed. A sampling/analysis member (10) is described having a sampling wand (15) which is suitable for use by untrained personnel under the relatively harsh and variable conditions found in the field, for example in fast food restaurants and other food preparation areas. The analytical signal in the disclosed device and methods can be based on luciferase/luciferin systems or a protein assay systems utilizing bicinchoninic acid.
