Review on Pack of 2 Solar Energy Security Alarm Lights for Car Vehicle Van Truck SUV - LED Flash Strobe Lamps with Anti-theft Warning by Uriel Arocha

Pack of 2, one red and one blue. Red is better known as car alarm sensor and that's what I decided to install. sticks pretty well to the dashboard. (Wipe the dash area and remove any oils or ArmorAll). It comes with a battery. It is powered by sunlight. It can also be charged via a micro USB cable. There is an on/off button. Its body is slightly transparent. When installing, remember to place it in a location where it can receive sunlight during the day, while rotating it so that you CANNOT see the power button when looking through the glass. (Obviously that makes it look "wrong"). As previously explained, I placed mine so that the front curtain visor rests on top of it and covers half of it but still allows a flash of red light to be seen. Works well for its price.
