Significant Aspects of the Construction of An Emergency Light Bar
An emergency light bar that is available in the market today is designed to perfection and endowed with features to make it functional and highly reliable. These lighting solutions are also affordable and offer complete value for money.
There are, several design and construction related aspects of an emergency light bar, which are thoughtful and impressive. Some of these aspects not only enhance the efficiency of the light bars, making them more useful but also extend their longevity. For example, full length light bars which come in lengths of 48 – 72 inches are provided with a high grade extruded aluminum platform and black polycarbonate base to provide structural rigidity. These lightweight materials provide sturdiness and vibration resistance to the light bar, which are important when mounted on speeding vehicles. Sealed modules with UV stabilized domes also add to the encapsulation, providing moisture and corrosion resistance to the lighting elements while preventing dust accumulation.
A very innovative design aspect of the emergency light bar is the staggered orientation of the various light heads. Full featured light bars have at least half a dozen front facing LED modules and an equal number of rear facing LED modules. Then there are corner LED modules to provide complete visibility in all directions. The light heads are sometimes placed in a staggered fashion for better visibility too. In fact, there are special mounting brackets which allow the light bars to be mounted at a considerable tilt. Height adjustability of the light bars is also provided through customized wedges, which ensure that the visibility offered by light bars, whether they are mounted on the roof or in the rear deck, is perfect. The fit should also be right for the contour of the vehicle surface, whether it is flat or curved.
There are two other design related aspects of an emergency light bar which are not usually seen in low quality models but are definitely a feature of high quality ones. One of them is the aerodynamic styling of the light bar which is important for the bigger models to reduce drag resistance and an annoying rattling sound when mounted on speeding vehicles. The aerodynamic styling also provides better fuel efficiency which is why professional manufacturers test the light bars in different types of conditions before arriving at their final design. Secondly, there should be a balance between dimensions of the light bar. For example, light bars which are around 72 inches in length are usually around 12 inches in width and under 5 inches in height. It is made sure that there is uniform weight distribution across the light bar, to prevent putting additional pressure on thinner vehicle roofs.
A good quality emergency light bar offers excellent efficiency due to several such design aspects which also indicate an attention to detail and rigorous testing done by the manufacturers. The alley lights and powerful take downs are also positioned for maximum viewing angle. Similarly, double Fresnel lenses are sometimes used along with lighthouse optics to make sure that the beams could go far and wide whenever required. The light bars which usually come with at least 2 years, no hassle warranty for service and spare parts, also have good controls for monitoring current and voltage in the circuit.
