Abstract
Abstract A safety flashlight (30) according to the invention includes a heavy duty magnet (1) secured to a cap (3) in turn connected to a main housing (9). A preferred flashlight (30) also includes a reflector cone (16) arranged to intercept a concentrated beam produced by a light bulb assembly (13) and radially reflect the light to make it noticeable irrespective of the angular orientation of the viewer with respect to the light (30). An electronic flashing circuit (10) is secured within the housing (9) using a synthetic rubber compound which insulates the circuit (10) and makes it less sensitive to shock.

Claim 1
Independent Claim
282 words
A hazard light comprising: (a) a battery housing suitable for holding a battery, the housing having an axis, a cap end and a lens end; (b) a light bulb assembly comprising a light bulb secured to the lens end of the housing suitable for operatively connecting to the battery and for producing concentrated light substantially parallel to the axis of the battery housing; (c) a cap secured to the cap end of the housing, a negative compression spring bearing operatively disposed within the cap having a back surface and a front surface and comprising a clip extending from the back surface suitable for holding an extra light bulb, and a substantially conical spring having its base in operative contact with the negative compression spring bearing, wherein the spring bearing eliminates skewing of the compression spring so that the spring will in turn maintain continuous contact with the battery; (d) a heavy duty magnet secured to the cap, whereby the hazard light can be secured to a ferrous object; (e) a blue lens secured to the lens end of the housing; (f) a lens clamp having a channel configuration for wedging the lens assembly into sealing contact with the lens end of the housing; and (g) a stryofoam reflector cone secured within the blue lens having an apex and a base, wherein the apex is located proximate the light bulb assembly, and wherein the outer surface of the cone radially reflects the concentrated light produced by the light bulb assembly through the blue lens, whereby the hazard light can supply a radially dispersed blue warning light capable of observation irrespective of the angular orientation of the viewer with respect to the hazard light.
