Portable and programmable emergency light bars find great use in emergency vehicles. Whether it is a cop van, a tow truck
or a patrol car, light bars help a great deal with their flashing patterns that
are easily customizable. Light bars are usually comprised of LED modules that
have arrays of LED that are put together to send out highly intense beams of
light. The frequency of flicker of these lights can be controlled, and the
pulse could be varied to get more than 15 or 20 flashes per second. Highly
intense and strobe light bars can be extremely attractive and at the same
time attention-grabbing, which is exactly the purpose for which they are used.
Emergency light bars come with mounting
hardware including mounting brackets, screws and clips which allows easy
installation of these light bars on the roof of the vehicle. These light bars
can send out highly luminous beams with low beam temperature that can be seen
from a great distance too. The combination of powerful sirens and beams of
light could be used to caution anyone anywhere. It could also be a sign for
imminent danger allowing those driving on the road to be more aware of their
surroundings. The optics put into use by the LED modules have been greatly
improved too, which means that the off-angle and all-round visibility has
increased to a great extent. For the light bars to be effective, this kind of
360-degree visibility is extremely important, especially when one vehicle is
leading the way for a few others on the road.

It is pleasantly surprising to note that in
spite of the powerful beams and blinding flashes, the truth of the matter is
that a 12 V DC source is used in most cases. Similarly, the power wattage of
the LED bulbs is usually 1W or 2W in most cases. The wiring is done well, and
the current flow through the circuit isn't threatening at any point. It is
thoroughly ensured that these led emergency light bars pose any threat at all thus
avoiding situations like external fusing or short circuits which could spark a
disaster. There is a full-function switch box which ensures that the lights and
the flashing patterns can be controlled. Flash pattern toggle switches are also
provided with these light bars to allow easy use of these lights. The wire
harness ensures easy installation. The generation III LED technology is
extremely energy-efficient and cost-effective too.
The arrangement of these LEDs in emergency
light bars can also be varied. The number of rows and columns could vary too,
with higher light bars having more than three rows. The incredibly powerful
signals generated by these LED modules also receive further assistance through
the use of chrome deflectors and lenses. Polycarbonate material adds to the
resilience of the light bars making them perfect for use under all-weather
conditions, whether it is foggy or rainy. The intensity of the LEDs could be
varied too depending on the usage.
