## Abstract

A global position system device including a host and a plurality of direction indicating lights is provided. The direction indicating lights are disposed at the host, wherein each direction indicating light is represented as one direction. The host controls the direction indicating lights such that one of the direction indicating lights is bright and the others are dark. Then, users are indicated by the direction indicating lights to make a turn or keep running straightforward.

## Claims

### Claim 1

A global position system device, comprising:
a host, used to output a direction signal; and
a plurality of direction indicating lights disposed at the host, the direction indicating lights are controlled to be bright or not by the host according to the direction signal.

### Claim 2 (depends on 1)

The global position system device of claim 1, wherein the host comprises:
a housing;
a circuit board, disposed in the housing and electrically connected with the direction indicating lights; and
a display panel, disposed on the surface of the housing and electrically connected with the circuit board.

### Claim 3 (depends on 2)

The global position system device of claim 2, wherein the direction indicating lights comprise three direction indicating lights respectively representing acts of turning left, turning right, and running straightforward.

### Claim 4 (depends on 2)

The global position system device of claim 2, wherein the display panel is turned off as one of the direction indicating lights is bright.

### Claim 5 (depends on 2)

The global position system device of claim 2, wherein the host further comprises a plurality of function keys disposed on the surface of the housing and electrically connected with the circuit board.

### Claim 6 (depends on 2)

The global position system device of claim 2, wherein each direction indicating light comprises:
a light source, disposed on the circuit board; and
a light guiding sheet, disposed on the surface of the housing and located above the light source.

### Claim 7 (depends on 6)

The global position system device of claim 6, wherein the light source comprises organic light emitting diode.
