Abstract
Abstract A flashlight comprises a housing adapted to accommodate batteries and an elongate extension having a proximal end connected to the housing and a distal end opposite the proximal end adapted to accommodate a light bulb. Electrically conductive leads carried by the extension are adapted to connect the battery to the bulb. The extension is formed of multiple strands of twisted copper wire or another material separate from the conductive leads that can be easily flexed by hand to assume a plurality of different shapes and that can retain a given shape indefinitely. The housing and the bulb can each be conveniently positioned and oriented independently of the other.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
144 words
A flashlight comprising: a housing adapted to accommodate a source of power; an elongate extension having a proximal portion connected to the housing and a relatively distal portion adapted to radiate light; and energy-transfer means carried by the extension and adapted to connect the source of power to the distal portion to facilitate the radiation of light from the distal portion; the extension being formed in such a manner that it can be easily flexed by hand to assume a plurality of different shapes and can retain a given shape indefinitely; whereby the housing and the distal light-radiating portion can each be conveniently positioned and oriented independently of the other; and wherein the housing is formed with a peripheral groove for accommodating the extension so that the extension can be wrapped around the housing for storage and to provide a compact configuration for use.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
35 words
A flashlight according to claim 1 further comprising a retainer mounted on the housing for engaging the extension when the extension is accommodated in the groove, thereby assisting in retaining the extension in the groove.
Claim 4
Dependent Claim
27 words
A flashlight according to claim 2 wherein, when the extension is accommodated in the groove, the retainer engages the extension near the distal end of the extension.
Claim 5
Dependent Claim
24 words
A flashlight according to claim 2 wherein the retainer functions also as a base to assist in supporting the flashlight on a supporting surface.
