Car Door Alert Light

Car Door Safety Warning Lights
Make every open door easier to spot—especially at night. These compact LED Car Door Safety Warning Lights flash automatically when the door is opened, helping alert approaching drivers, cyclists, and pedestrians to the open door.
With a bright 5-LED strobe, the light rapidly flashes during the first 6 seconds for maximum visibility, then continues operating before automatically switching off after approximately 180 seconds. The built-in sensor and wireless design mean no wiring, drilling, or complicated installation—simply attach it to your car door and you're ready to go.
