## Abstract

An improved structure of reflective warning triangle which has many holes inside the triangle for plugging in the bright red LED's, said reflective warning triangle having a reflecting plate and a transparent plate together. Said reflective warning triangle has tight washers to seal the holes containing the LED's to achieve the goal of a water-proof device. The LED's are series-parallel connected six by six so as to keep the reflective warning triangle of the present invention shining even when part of the circuit is short-circuited.

## Claims

### Claim 1

A reflective warning triangle comprising:
multiple bright red LED's fixed in and protruding from holes in legs of the triangle so as to allow greater dispersal of the light emitted therefrom, the connecting points of the LED's and the triangle being sealed by multiple washers;
the legs of the triangle comprise a reflective plate and a transparent plate, with several sets of circumferential protuberances in differing heights and a scoop channel being provided on a back of the transparent plate and a front of the reflective plate, said protuberances and channel serving as the means to join the transparent plate and the reflective plate to form the leg of the triangle, a gasket being provided intermediate the two plates to ensure proper sealing; and wherein
said LED's are series-parallel connected to each other six by six.

### Claim 2 (depends on 1)

The reflective warning triangle of claim 1 wherein:
a connecting device and positive and negative plugs, which allow the battery and lighter of the car to serve as the source of electricity for the reflective warning triangle are installed in the reflective warning triangle.
