The dashboard lights are used to get the attention of the spectators as quickly as possible. These lights, due to the nature of their use, must be rugged and operate continuously in all weather conditions. LED lights are most often used for these as LED bulbs have the ability to run for 100,000 hours which is extremely useful.
There are many different varieties of dash lights depending on the nature of their use. There are dual lights that mount to provide wide modules with extremely wide angles. A variety of colors are used to accentuate the effect in conjunction with colored lenses, making them highly efficient in attracting everyone’s attention. The dashboard LEDs can also be programmed to glow in set patterns. For example, the alternating red and blue lights could glow at intervals ranging from 10 seconds to a tenth of a second, depending on the need for the time. They are very easy to assemble and customize on the fly, a feature that adds to the popularity of these lights.
The number of light emitting diodes used in these dash lights also varies depending on the emergency and use. For example, you could find 48 LED lights, double and single head lights, extreme assemblies that have hundreds of LEDs, etc. The variety of LEDs and the alternating flash patterns that can be used make these lights ideal for a dazzling effect that is often required. To increase their effectiveness, these lights can also be mounted on the windshield, to accentuate the high-power output in different colors such as red, amber, blue and green.
Dashboard lights can be powered by both solar power and rechargeable batteries, although the former is a cheaper option. The carbon footprint of these lights is extremely low for the performance they offer, making them a favorite with environmentalists too. The dissipated thermal energy is also very low, which allows them to be preferred over halogen lights that have been used so far for high performances. The LED dash lights used in police vehicles and mounted on highway poles are operated through their own control panels and are extremely safe to use. There is also no risk of short circuit that arises in electric lighting.
Dashboard lights are generally based on robust diode operation, where the output is not dependent on current passing through a wire as is the case with incandescent bulbs. Made from various assemblies comprising minute light arrays, these can be used to create multiple and intricate patterns, customized to very specific requirements. A 3-watt lightbulb strip might suffice in most cases and can be easily connected or detached from a circuit, depending on the required output. Thus, these lights, in addition to being cheap, robust and easy to maintain, offer a lot of variety and customization. This has literally eliminated all kinds of competition to these lights, especially when it comes to flashing patterns that are necessary to draw attention to an emergency.
