ABSTRACT:
A portable light (10) has a rigid base (12), a power supply (14) having first and second poles (16, 18) within the base and a light source (20) positioned in the base (12). The light source (20) has first and second lead-ins (22, 24). The first lead-in (22) is in contact with the first pole (16) of the power supply (14). Electrical isolation means (26) isolates the second lead-in (24) from the second pole (18) of the power supply (14); and a flexible cover (28) is fitted to the base (12). The cover (28) includes at least one portion (30) that is contactable with the second lead-in (24) whereby pressure on the at least one portion (30) defeats the electrical isolation means (26) and causes a connection between the second lead-in (24) and the second pole (18) of the power supply (14) to actuate the light source (20) while the pressure is being applied.
