## Abstract

A visual warning device has both a warning function to provide various colored flashing lights and a lighting function to adjustably project the lighting in preferable direction, which at least comprises a lighting device comprising an interior spotlight fixedly placed in the inside of the visual warning device and a beacon-like waterproof cover for mostly shielding the interior spotlight by outside exposure securely fastened onto the visual warning device, so that the interior spotlight has no required for an additional waterproof means pivotally mounted thereon as before; in particular, the interior spotlight further has both a vertical drive means and a horizontal drive means designed by uncovered structure, due to both the vertical drive means and the horizontal drive means unnecessarily concealed or placed in the inside of the interior spotlight as before, the interior spotlight has much simpler structure than before and more saving cost.

## Claims

### Claim 1

A visual warning device comprising a box-like flashing-light shell having LED-based warning light means for displaying flashing symbols, reverse characters or arrows, a covered plate having one or more receiving holes evenly formed thereon and tightly covered onto and assembled with the flashing-light shell and one or more lighting device through manually remotely control or/and wireless remotely control to adjust the lighting projected in preferable direction,
wherein each lighting device comprises an interior spotlight fixedly placed in the inside of the flashing-light shell and a beacon-like waterproof cover for mostly shielding the interior spotlight by outside exposure securely fastened onto the receiving holes of the covered plate, and the interior spotlight further comprises
a light module comprising a bulb for lighting, an extended lever served as a linking lever for making a pivotal combination and a vertical gear member firmly mounted onto the extended lever;
a vertical drive means comprising a reversible gear motor having an output shaft joined with a pinion means;
a horizontal drive means comprising a reversible gear motor having an output shaft joined with a pinion means;
a base means fixedly mounted in the inside of the flashing-light shell and comprising a cross spacer integrally formed inside and a static gear firmly fastened onto the cross spacer; and
a disc-like swivel seat comprising
a first risen spacer provided for making a pivotal combination with the extended lever of the light module through a first pivotal bolt freely passed and connected with a first fastening nut;
a second risen spacer provided for the vertical drive means by uncovered design firmly mounted thereon to have its own pinion means engaged with the vertical gear member of the light module for having the ability to drive the light module moved in tilting movement;
a first recessed hole provided for a second pivotal bolt mounted therein to join the swivel seat and the base means together as a pivotal assembly with a second fastening nut; and
a second recessed hole provided for the horizontal drive means by uncovered design firmly mounted therein to have its own pinion means engaged with the static gear of the base means for having the ability to drive the swivel seat and the light module moved in panning movement.

### Claim 2 (depends on 1)

The visual warning device as defined in claim 1, wherein the LED-based warning light means comprises a microcontroller, a power supplied means to supply 12-volt DC power and a plurality of programmable LEDs to flash colored light signals in one or more predetermined patterns or sequences, wherein microcontroller is programmed to control the power supplied means to supply electrical power required for the programmable LEDs, the light module, the vertical drive means or the horizontal drive means respectively.

### Claim 3 (depends on 1)

The visual warning device as defined in claim 1, the base means has a flange with plural fasten holes provided for fixedly mounting the interior spotlight in the inside of the flashing-light shell through fastening parts.
