Review on Wecade 12w 12 Leds Car Truck Emergency Strobe Flash Light Windshield Warning Light (Red/White/White/Red) - Powerful Safety Signal for Vehicle Emergencies by Jon Ford

My husband, myself and my eldest son work in our city's fire department. We needed turn signals for him in our private cars. I bought three of them hoping they would work well. As long as they are great! I only have one small issue, which is that the suction cups seem to lose their suction power after a day. Not all, but sometimes one side, then the other. At some point I might think about bigger cups. I don't find that a big problem so I'm still giving 5 runs! The lamps themselves are well made, look good and work very well. I have it on top of my windshield just behind the black dots on your windshield. We thought this might affect the visibility of the emergency lights. nope! They shine through. There are also several settings for changing the blink pattern. We are very impressed!
