You’ve probably noticed all the special warning equipment around a construction site when passing by one. Well, that’s because construction areas are somewhat dangerous and those warning signs shouldn’t be taken lightly. You’ve also noticed them on construction trucks that carry heavy and sometimes even hazardous materials. However, not everyone can use warning lights freely. In fact, there are some special regulations when it comes to the subject. Regardless, if you’re one of the exceptions, and require them on your construction site or on your vehicle, there are typically multiple warning light types to choose from.
LED Warning Light
By far the most popular warning light nowadays is the LED warning light. The reason for this is their versatility since they feature blinking, rotating and continuous modes plus they are durable and come with low power consumption. They’re ideal for machinery because they’re incredibly vibration and shock resistant as well.
Flashing Strobe Beacons
These warning lights utilise xenon gas-filled glass lubes to produce bright illumination when energised. The same technology is used for flash photography and in strobe lights. Typically, they flash once per second, but this can very from device to device. These are some of the more popular warning lights and are widely used for toxic gas leaks, chemical spills, evacuation alarms and for warning of structures and moving machinery like service vehicles, lifting equipment, gates, doors and barriers.
Rotating Mirror Lights
Rotating mirror lights utilise a motorised reflector and a halogen lamp to shed a 360 degree rotating light beam. They have a significantly higher output intensity than conventional incandescent light bulbs. Rotating mirror lights are popular among moving vehicles and alarm systems because of the high degree of signaling effect they provide.
These lights utilise self-contained circuitry and incandescent light bulbs to get the desired blinking effect. Some models have a fixed blinking frequency while others can be user-selectable. These are budget-friendly but are inferior to LED warning lights in almost every other way. However, they’re still good at getting the point across.
Continuous lights utilise filament-style halogen lamps or light bulbs and are the more affordable choice for process status indication and machinery. Again, they’re outperformed by LED lights in almost any way, especially if you’re supposed to use them on a shock and vibrating surface. And just as the case is with blinking lights, they’re good enough to get the message across at an affordable price.
