During nighttime the guardrail lamps send out lights in such a striking way that they can guide the vehicles to prevent traffic accidents. Further they are of great importance to landscape of the whole city.

The guardrail lamps consist of four parts: Outer tube, lamp tube, controller and connector.

Outer tube: Made of engineering polycarbonate of high strength (PC) and manufactured from bulletproof glass.

Lamp tube: Adopts new type LW-BGR tube of patented technology. The tube use composite cold and hot light source, which has a long life span, long duration in hot and cold environment, fast start-up and instant reaction. It is more reliable than luorescent lamp, neon lamp and incandescent lamp and is of high anti-shock feature especially suitable for use on bridges.

Controller: Utilizes computer and digital technology and long-distance communication technology and under a balanced phases long-distance transmission can realized. All tube can be started and changed simultaneously and flow speed can be adjusted at will to still or mobile state.

Connector: Adopts special plug, which makes the installation and dismantling as well as replacement convenient because no wire is used.

The four parts are assembled under hot condition, which makes the device has a waterproof, dust-proof and mould proof feature.
