Review on High-Performance SpeedTech Lights Z-3 LED Strobe Light - Ideal for Police Cars, Construction Trucks, Service Vehicles, Plows, and Emergency Vehicles. Surface Mount Grille Flashing Hazard Beacon Light with Clear/Clear (White/White) Color by Joey Gilbert

Before I start this review I have to say that I myself am impressed with the packaging and the care that is taken to ensure the merchandise gets to me undamaged. These lights are exceptional to build and have a very solid build and real glass finish which I didn't expect for the price. Not only are these lights bright, they dazzle at night and are incredibly visible during the day. I have a TIR with a field of view of about 35 degrees so you have to be careful where and how you install it to get the light output going where you want it. I really wish I could feature some of the linear lightheads for Speedtech on my YouTube channel. Regardless, I plan to get some to do away with the rear warning on my car. Pros Incredible value Very solid construction Real glass optics Brilliant bright Cons The light guides were a bit short at about 12 which I found difficult to work with in some areas of my Crown Vic. 18" or 24" would be perfect. Better and faster flash patterns are needed, but what comes with the device is acceptable. strike, not scatter. If you want perpendicular propagation, you must get linear. Very happy with everything I've seen so far.
