Once again it's that time of the year when people seem to be at their best, holiday programs and ads fill our TV screens, and we anticipate gaining at least one or two more pounds (if we're lucky!). One of the biggest parts of the holiday celebration is the putting up of Christmas lights. Everyone wants to have that house that is so beautifully lit it stops people in their tracks, but that can be a hard thing to do once you've considered the amount of energy used during this time of the year on those holiday lights alone.
According to a study conducted by the Washington State University Energy Program the average cost of lighting up 5 standard C-7 light string with 25 incandescent bulbs for 150 hours uses up 500W and costs around $6.20. That's almost $27 for very few lights. Most houses probably use up 2-3 times that. So how can you display the holiday spirit and save energy at the same time?
The solution to this problem is LED light strings. While incandescent bulbs use many watts of energy to light up one string of lights, an LED string uses as little as 2.4 watts for 25 bulbs, with a maximum consumption of 210 watts. You can save even more energy by hooking the lights up to an Outdoor LED countdown timer. This timer has a built in photocell so you have the choice of selecting dusk-to-dawn operation or a programmable mode with a 1 to 9 hour countdown after dusk. E.g. you can set the lights to turn on at dusk and have it turn off automatically after 4 hours.
In addition to being energy efficient, these LED light strings are much safer to use, as they use up less heat making them cool to the touch. This is possible because the lenses on the LED lights, such as a pure white C6 bulb, are made out of solid epoxy which is nearly indestructible. Outdoor LED light strings come in strings as long as 8 feet (with 4 inches of spacing between each bulb), so you don't have to worry about limiting your Christmas displays. The lights can be used both indoors and outdoors, creating the beautiful holiday environment you're looking for without leaving you with the guilty feeling of wasted energy.
These days LED traffic countdown timers are easily noticeable on the street traffic due to their power saving and cost effective nature. A great number of streets worldwide have switched to LED traffic lights and have brought a revolution in the lighting industry. this is great for the environment as well.
People know traffic lights with different names, like spotlights and traffic signals. These play major role to control the road traffic. Initially, these lights comprise of only two lamps i.e. a green and a red color, which has still found its usage in many countries. However, in case of those traffic lights, there was no way to operate changing of lights automatically; instead, individuals have to change or operate it manually. In other words, traffic officers have to remain present to turn the lantern for making sure of facing right light for the traffic.
If you go for a brief description, traffic signals mainly assure the safe possible flow of traffic in any particular location. Traffic lights of modern times come in three different yet common colors i.e. green, yellow and red, all of which made by using LED bulbs. If you give time to know 
While crossing the road, we are always taught to look both sides and nowadays we are asked to watch the Traffic signal. The Traffic Signal is a very important element of any road be it a highway or a busy lane. The Traffic Signal has three lights namely, ‘RED’ for ‘STOP’, ‘YELLOW’ for ‘WAIT’ or ‘BE READY’ and GREEN for ‘GO’. The lights are arranged vertically in the order or ‘RED’, ‘YELLOW’ and ‘GREEN’. The three lights appear for the vehicles and when it is ‘RED’, people are supposed to cross the roads.
The signals are installed within one black vertical box containing colour LED lights usually Circular in shapes and this box is attached to a high pole so that the Drivers can notice the signals and follow them from a far distance. The usual count for the lights remains for 1 minute or 2 covering the three lights. On an average of every 5 minute, the light changes from ‘Green’ to ‘Red’. Nowadays, signals show human figures instead of simple lights. When the Human walking figure is ‘Red’, the vehicles move while when the same figure shows ‘Green’, the people cross the street or the road. The boxes can thus be vertical rectangle, or a horizontal rectangle or a square even. Henc, the 
Digital screen that you see attached to the containers holding Gas or Petrol while you go to fill up your cars or any other Vehicles are the LED signs. These gas signs help you know how much of the liquid you are getting in your vehicle and accordingly the amount you are supposed to pay. Each machine of this category calculates accordingly and gives you the result. This machine is helpful, as one does not need to calculate manually to pay.

LED is the abbreviated form of Light Emitting Diode. It implies a type of semiconductor component able to produce light of very high intensity. Unlike any other halogen bulbs or transcendent light sources, these modern yet advanced light systems and 
Although, scientists have undergone significant developments of primitive light emitting diodes during the late 60s, it has dedicated some time to bring improvements in enough efficiency to expand real applications of existing technology.
Once you move out of the building and analyze at the street level, you will still find the usage of 
Most of the products related to LED gas display systems come in large numbers of size options, where height ranges from minimum 8 inches and goes up to 48 inches guaranteed to fit perfectly into the already existing sign or align back to back in between two different existing poles.
They are manufactured using high quality material and ensure complete safety. They are available for various applications and used as either flashing or instant light source. Hazard lights and 
Everyone knows that electricity is a non-renewable source of energy; but the fact is also that without electricity one cannot imagine life even for a second. People cannot imagine lives without electricity but they can think about various ideas about saving this precious energy source. As an individual, he or she can go green and replace our electric fixtures with something that consumes less power like the LED lighting fixtures but for electricity saving on a larger scale, we should come forwards and also contribute in replacing the normal traffic signals with the LED traffic signals.
LED is a small semiconductor, which emits light when current is passed through it. There is no filament kind of thing in it like the ordinary incandescent bulbs. When they are used in traffic signals, hundreds of LEDs are connected together in a cluster to achieve that high-brightness.
