Emergency light bars have witnessed a lot of innovation in
recent times. Super bright and linear light fixtures are commonly used these
days in a lot of places where there is a need for bright and attention seeking
lighting. You can use these light bars on top of emergency vehicles, be it
patrol cars, cop cars, vehicles belonging to administrative officials who need
a clear way on the road or ambulances that need you to help out by offering
them a clear path.
It is obvious that
emergency vehicle lighting needs to be intense to catch everyone's attention
and should be able to flash and blink to send signals to others around.
Moreover, these should be easily installable and you should find it easy to
mount them on the front, rear or sides of a vehicle.
Emergency light bars come with both steady output as well as
flashing output. There are built-in LED drivers which can ensure a uniform
output of light. Similarly, some light bars also come with dimming circuits
which allow you to adjust the intensity of the lighting based on your needs. In
other words, depending on your usage and the time of the day, the lights can
turn from bright to dim and vice-versa. This also helps in saving some energy
if needed, not to mention that dim lights in bright areas are more soothing
than bright beams flashing on the rear view mirrors of a passenger car ahead.
Emergency lights bars vary in length from as small as 3
inches to longer than 50 inches. The number of LEDs used by these lights also
varies from half a dozen to more than couple of dozens. The super bright LEDs
consume very less energy and with 12 V DC source, the 1W LEDs are capable of
emitting strong beams of light with low beam temperature.
The light bars are
usually available along with plenty of accessories which make installation and
use very easy. There are power cables, cigarette plug switches for turning them
on and off and interconnect jumpers if you need to connect several lighting
fixtures together. You would also get DC power supply, mounting clips, brackets
and magnets, which could be useful in offering vibration and impact resistant
installation of emergency lights on the roof of a vehicle. There are switch
board panels, controller box and pattern selectors as well in order to vary the
flashing and for other functions.
Emergency light bars are not only scalable but also
extremely versatile. This is because you can easily replace one LED module with
another. You can separate out one segment of LED arrays from a light bar and
replace with another. This way you can always be prepared with backup.
Moreover, you can add or remove modules depending on how
much lighting is required. Obviously, one can never be sure of the amount of
lighting needed in case of a car crash or spillage on the highway, especially
on winding and treacherous roads. The lights are usually water, dust and
corrosion resistant.
