Nightsearcher's Pulsar LED Warning Lights come in a bright blue colour. They are fully rechargeable and have 9 light modes including flashing and SOS, making these units essential for emergency alert. They are also ideal for traffic control, signalling, hazard awareness, lighting pathways and tracks, perimeter and highway marking, and general vehicle safety. Small but robust, Pulsar lights are virtually indestructible, manufactured from shock-resistant plastic, they can withstand most vehicular damage if crushed and are waterproof up to 10 metres. The set of five is fully charged and protected in an ingeniously designed case that can utilise both supplied mains and vehicle chargers.
