A lamp for a nozzle includes an annular housing having an outer peripheral wall and an inner peripheral wall, the inner peripheral wall defining a central cavity extending through the housing. The central cavity lies along a central axis and enables the housing to be mounted circumferentially around the nozzle. A securing device is connected to the housing for securing the housing to the nozzle. A lighting unit is positioned within the housing and encircles the central cavity. An annular shaped first lens is positioned over the lighting unit. A retaining member secures and seals the first lens to the outer and inner peripheral walls of the housing for hermetically sealing the lighting unit within the housing.
