Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a western umbrella with an indicator light that can be used safely even in relatively dark places with poor visibility, such as at night.

Prior Art In a relatively dark place with poor visibility, such as at night on a rainy day, where there are no street lights, it is difficult for the driver of a car to see pedestrians holding umbrellas. As a result, pedestrians are at greater risk of traffic accidents when walking on roads without sidewalks or when crossing at crosswalks.

Conventionally, as a solution to the above problems,
At least a part of the stone protrusion forming the top of the western umbrella is provided with a transparent part, and the stone protrusion is equipped with a light source such as a light bulb,
