warning lights need to possess certain characteristics to be extremely reliable and efficient. These lights need to ensure that the cautionary signal that one wants to send is actually sent across without fading or being washed away, as could be the case during harsh weather conditions. The most important attribute of a warning light head is the penetration and visibility that comes along with it. LEDs produce highly directional light beams in a particular direction which are highly penetrative. In fact, clear lenses and mirrors can be used to collect light beams from multiple LEDs and then focus them into a single direction. The visibility can also be enhanced by using colored filters that can flash colored light beams for greater attention grabbing ability.

warning lights should be reliable, for which they need to be heavy duty resistant and resilient to all kinds of weather conditions. Good quality warning light bars come with extruded aluminum platforms along with polycarbonate base that makes these lights vibration and moisture resistant. Compression fit gaskets further enhance the encapsulation. Thermal ...
... heat management is also achieved by sealing the lenses to the polycarbonate base. ABS vacuum formed housings are used to ensure that some of the light heads can be mounted externally.

warning lights become far more effective when there are plenty of flashing options available. This is why modern LED light bars have built in flash patterns and a solid state, reliable and durable flasher. Dozens of flash patterns including single, double, triple and quad flash, sequential and continuous flash patterns are provided for different warning signals that need to be sent out. LED modules are configured together so that the warning signals can be synced and all the light patterns can be flashed in synchronization from different light heads, whether it is the super bright LEDs or the corner strobe lights. Moreover, the flash patterns should be easy to operate or alter. This is a feature that enhances the effectiveness of the warning light.

There are plenty of choices as far as colors of warning lights are concerned. They can be flashed in red, amber, blue or green depending upon the signal to be sent. Colored lenses or filters can also be used over white LEDs for split color sections, which produce different colored light beams. The availability of color choices also enhances the number of permutations and combinations when it comes to flash patterns. Traffic advisor lights with green or red arrow markers, if present, can add to the effectiveness of the light bars.

One of the most important aspects of warning lights is their energy efficiency. LEDs are mostly used in light bars as they can provide impressive luminosity with just 4 -5 Watt power rating. Several such LEDs can be configured together to get the required amount of luminosity. Intensity control knobs are present with some LED devices so that the lights can be dimmed when high intensity is not required. One can also choose between steady burn and flashing warning light.
