Describe: 100% brand new and high quality! This vehicle anti-theft light product can protect your property from potential thieves at night. Bright flashing LED lights mimic the lights used in expensive vehicle alarm systems, making it easier for thieves to find targets through your vehicle. Lights can also prevent intrusions at night. Easy to install and looks clean on the dashboard. The LED lights will flicker at night, but will not flicker during the day. (If you want it to shine during the day, you can cover the other end with dark paper.) This LED alarm does not require a car alarm system. No wires are needed, just stick it on the roof of the car with the corresponding glue. Solar energy can be absorbed and stored in high-efficiency solar cells. You do not need to install batteries. It is powered by solar energy. I have tested it myself and the LED can flash all night when there is enough sunlight during the day. You don't need to put it directly in the sun. The sunlight above the dashboard is sufficient. No matter you put the switch on or off, it can be charged by solar energy. Size: 5*2.5cm (2*1 inches) The switch is small. You need a ballpoint pen or small stick to push it. Color: blue, red (please note the choice, otherwise it will be shipped randomly) The package includes: 1 x warning light
