Description

Technical Field

[0001] The utility model relates to the technical field of automobile warning light equipment, in particular to an automobile tail warning light. Background Art

[0002] With the improvement of living standards, cars are becoming more and more popular. During the driving process, the car may have to stop temporarily on the road due to a malfunction or accident, which may easily cause the rear car to rear-end. Although all vehicles have double flash warning lights to remind the rear car of the abnormality of the front car, the warning effect of the double flash indicator is limited. Traffic accidents caused by the temporary parking or deceleration of the front car still occur frequently. In order to improve the safety of the car during driving, a car tail warning light is needed. At present, the existing car tail warning lights on the market have a relatively complex structure, are difficult to assemble, and have high production costs.

[0003] Therefore, the prior art needs to be improved. Utility Model Content
