The Importance and Different Types of Traffic Lights


People have become so accustomed to vehicles, that most of them don’t even realize that they are operating tonne-heavy machines that can injure or kill someone in the blink of an eye. Moreover, we constantly see people drinking and driving, texting and driving, etc. and some of us find that completely normal, which trust me – it’s not. However, believe it or not, most accidents don’t happen because of impaired or careless drivers, but they occur on intersections that don’t have traffic lights. One would think that driving rules and experience would be enough to safely cross intersections, but most people drive with the mentality of – “I need to be somewhere ASAP!” and that’s when these things happen.

Simply put, traffic lights are devices meant to improve traffic safety and flow, and make roads as idiot-proof as possible. However, their use is more widespread than just roads. Many restaurant and private parking owners buy a traffic light to help regulate the traffic in their lot. Well-functioning traffic is beneficial to everyone involved, including pedestrians. So, if you’re looking to buy a traffic light, you’ll come across various models that feature up to five aspects and have different types of light bulbs.

Depending on what you need traffic lights for, your choice will obviously vary. Parking lots, for example, usually need two aspects – one green and one red, to let people know whether there’s available parking space in the lot or not. On the other hand, a road intersection may require anywhere from two to five aspects. When it comes to bulb type, LED is typically the best choice, simply because LED bulbs are durable, consume significantly less energy than incandescent bulbs, and provide more illumination, which is extremely important when it’s foggy, for example.

If the traffic lights you need have to abide by strict rules and regulations, then factors such as working temperature, dominant wavelength, light intensity, lens diameter, input voltage, working humidity, housing, rating, average lifespan of LED, view distance, mass, sun visors and mounting bracket should all be considered. If that’s not the case, then you’re better off with buying any type of traffic light and have it placed wherever it is you need it, because having some traffic control is better than having no traffic control whatsoever.

That being said, if you think your facility might need traffic regulation – it probably does. Traffic lights are an affordable investment that will improve traffic safety and flow. There are numerous types to choose from, with LED bulb models being the most popular ones.
