## Abstract

A light having a body defining a battery casing for storing one or more batteries, a head rotatably mounted to the body, the head and the body including complementing, contacting, rounded portions, the head further including a light display and an LED light source, the LED light source being electrically connected to the battery casing for providing electrical power to the LED light source when batteries are disposed in the battery casing.

## Claims

### Claim 1

A light having a body defining a battery casing for storing one or more batteries, a head rotatably mounted to the body, the head and the body including complementing, contacting, rounded portions, the head further including an LED light source, the LED light source being electrically connected to the battery casing for providing electrical power to the LED light source when batteries are disposed in the battery casing, and wherein a pair of wires provide the electrical connection between the battery casing and the LED light source, the pair of wires include slack when the head is at a central position, the wires becoming more taut when the head is rotated in one direction or the other.

### Claim 2

(canceled)

### Claim 3 (depends on 1)

The light of claim 1, further comprising a spring-biased clip mounted to the body to permit the light to be clipped to another object.

### Claim 4 (depends on 1)

The light of claim 1 wherein the head is generally cylindrical in configuration.

### Claim 5 (depends on 1)

The light of claim 1 further comprising a phosphorous cover disposed over the LED light source to diffuse the light being emitted from the LED.

### Claim 6 (depends on 1)

The light of claim 1, further comprising a switch to turn the light on and off, and a flexible plate disposed over the switch and mounted to the body such that be depressing the flexible plate the switch is turned on and off.

### Claim 7

A light having a body defining a battery casing for storing one or more batteries, a generally cylindrical head rotatably mounted to a complementing rounded portion of the body, the head further including a light source, the light source being electrically connected to the battery casing for providing electrical power to the light source when batteries are disposed in the battery casing.

### Claim 8 (depends on 7)

The light of claim 7 wherein the light source comprises an LED light source, a pair of wires provides the electrical connection between the battery casing and the LED light source, the wires being slackened when the head is in a central position and the wires becoming taut when the head is at an extreme range of rotation, the light further comprising a spring-biased clip mounted to the body to permit the light to be clipped to another object.

### Claim 9 (depends on 7)

The light of claim 7 wherein the light source is flush with the exterior of the generally cylindrical head.

### Claim 10 (depends on 9)

The light source of claim 9 wherein the light source comprises an LED with a lens covering the LED, and the lens is flush with the exterior of the generally cylindrical head.
