## Abstract

A truck bucket door has a door panel and at least one warning device. The least one warning device is mounted on the door panel, and each one of the at least one warning device has a casing, a circuit board, a detecting switch, and at least one illuminating device. The casing is translucent and is securely mounted on the door panel. The circuit board is held in the casing. The detecting switch is mounted on the circuit board and has a capability of detecting a movement of the door panel. The at least one illuminating element is mounted on the circuit board and is electrically connected with the detecting switch.

## Claims

### Claim 1

A truck bucket door comprising:
a door panel; and
at least one warning device mounted on the door panel, and each one of the at least one warning device comprising
a casing being translucent and securely mounted on the door panel;
