Review on ASPL 8Pcs Sync Feature Ultra Slim 12-LED Surface Mount Flashing Strobe Lights For Truck Car Vehicle LED Mini Grille Light Head Emergency Beacon Hazard Warning Lights (Red/White) by Chris Jenkins

I bought these for a home-made security system. They are blindingly bright, and can be seen from a long ways away. I like having complete control of how they work and absolutely love that they included the synchronization wire and pattern select wire separate (not already wired to a switch) so I can wire them the way I want to. The instructions are clear and anybody can hook them up. I had shopped relentlessly for alarm lights for the home, but none I bought are nearly as bright, water-resistant as these (made for cars). NOTE** These are not for 110 volts house circuits, they are designed for a 12 volt system. I'm using a simply 12 volt power supply to drive them.
