KaiDengZhe 4 LED 4 in 1 Strobe Warning Light DC12V Emergency Flashing Beacon Lamp Ambulance Police Light Wireless Remote Strobe Warning External Light For Truck Trailer Caravan Camper (Blue)

These are good, bright enough, loads of different strobe patterns, compact and tidy. With the strobe unit being wireless, you can wire it right up to your battery and won't need to run cables into the cockpit. The only draw back is that the lights can be triggered by other wireless items such as a neighbour's car key fob and can cause the lights to come on when you are away from the car. The only way I could combat this was to remove the fuse from the fuse holder I wired to the battery when I'm not with the car.
