Abstract: A vehicular lamp suitable to be employed as a snowplow light employs two twin-element bulb lamps of the bayonet type as combined turn signal and parking lights, and has a lampholder arranged for mounting both the lamps. The lampholder includes a conductive bulb retainer plate and a pair of conductive resilient contact strips disposed in parallel with each other and in parallel relation with and spaced from the retainer plate. A lampholder body of a non-conductive plastic material mounts the bulb retainer plate and the contact strips, with the latter enjoying at least limited flexing motion towards and away from the retainer plate. A non-conducting resilient member, which can be an elastomeric compression grommet, is seated in the lampholder body behind the contact strips at the location of the end pins of the lamp, and urges the contact strips into contact with the associated lamp end pins.

Abstract: A rotary beacon for use in emergency equipment where a turntable carrying electric lights rotates with respect to the base.

Abstract: A flashing signal light that includes a rotatably mounted signal generator formed of a light transmitting material and a non-rotatable source of light adapted to direct light into the generator along its axis of rotation. A pyramid shaped prism is associated with the generator having its apex positioned along the axis of rotation. The prism surfaces intercept the light directed into the generator, split the light into one or more beams and direct the beams towards the exit face of the generator in a plane that is substantially perpendicular to the axis of rotation.
