These multi-mode LED hazard warning lights are small but robust and are manufactured in a shock-resistant plastic housing that is waterproof up to 10 metres. They are virtually indestructible, withstanding most vehicle weights if crushed. Their built-in magnets allow them to easily be attached to vehicles and other metal surfaces. Designed with safety in mind for traffic control, signalling, hazard awareness, zone demarcation, and vehicle safety. They are perfectly suited for professional applications such as Emergency Responders, Fire, Police, and Highway Services.
