A traffic warning sign is a type of traffic sign that indicates a hazard ahead on the road that may not be readily apparent to a driver.
In most countries, they usually take the shape of an equilateral triangle with a white background and a thick red border. However, both the color of the background and the color and thickness of the border vary from country to country.
In the People's Republic of China (except for Macau and Hong Kong), traffic warning signals appear with a black border and a yellow background. In Sweden, Serbia, Bosnia and Herzegovina, Greece, Finland, Iceland, the Republic of Macedonia and Poland, they have a red border with an amber background. The polar bear traffic warning light in Svalbard recently changed from displaying a black bear on white background to a white bear on black background (both signs are triangular with a red border). Some countries (like France, Norway, Spain) that normally use a white background have adopted an orange or amber background for road work or construction signs.
LED traffic warning lights are turning out to be the most innovative alternative of traditional traffic lighting options such as incandescent lamp or halogen warning light. Traffic warning lighting has undergone great changes in the last few decades with the developments in LED light systems. They have a lot of plus points to their credit - they are cost effective, energy efficient, smaller, brighter, run cool, and last longer. LED is also a greener alternative to non-rechargeable battery operated solutions. They are also highly adaptable, making them suitable in a wide range of applications compared with conventional sources of lighting.
Traffic lighting utilizing LED display technology is considered to be the future. LED lighting offers long life, reliability and low power consumption - perfect for emergency lighting applications. There are environmental benefits too in reducing the number of fluorescent tubes thrown into landfill.
LED warning lights are portable devices that are used for dealing with emergency situations such as power outrages and blackouts caused due to hurricanes, tornadoes, lightning, flooding, and blown out street transformers. They are designed for rough use and can withstand shocks and vibrations that may occur while using it in emergencies.
Proper lighting is fundamental to the safety of our society. We rely upon lights used in exit signs and street lamps. In extreme conditions reliable lighting is essential, so it's important to know how to solve any emergency lighting problem.
