There are some common characteristics that you should look for in police lights and sirens. There are many similarities in the way you judge good emergency lighting equipment and high quality sirens. Emergency lighting equipment like light bars, mini bars, dash lights, deck lights, visor lights, traffic advisors, hideaway lights and strobe light heads are useful in creating a powerful warning signal that can be sent out to alert other motorists on the road or to relay a warning to those looking out for the signal. However, there are scenarios where the emergency lighting equipment isnt effective on its own. This is why the emergency lights perfectly complement the sirens which can reach across to those who cannot see the lighting. A good example would be a high traffic road, where motorists ahead cannot be alerted with flashes of warning signals but can be warned with the help of a siren.

One of the most important characteristics to look for in police lights and sirens is resilience to tough conditions. This could be heavy duty usage as well as bad weather conditions. While polycarbonate base and extruded aluminium platforms are used for light bars, sirens come in a casing of glass filled black nylon or high impact plastic. The focus is on finding a casing that is lightweight, yet rugged and robust. Good emergency lights and sirens are moisture resistant too, so that they can be mounted externally for greater effect. It allows you to utilise them in all situations without any handicap.

Another important characteristic in good police lights and sirens is mounting flexibility. Universal brackets, L shaped brackets and 2-way brackets are available to mount the lights or sirens with ease on the roof of the vehicle, in the front or even near the rear deck. All surface mount lights and siren systems can provide great flexibility. Magnetic mounting is used as a temporary option for both emergency lights and sirens which are lightweight. 4 magnets with a combined pull of over 60 lbs can be more than handy for temporarily mounting the sirens and emergency lights, with special rubber pads to protect the finish on the vehicle.

Effective police lights and sirens are efficient because of their operational ease. An important fact that contributes to operational ease is the Scan Lock pattern selection mechanism. While it helps in picking any of the two dozen flash patterns configured into the emergency lights, it could also be used for scanning and selecting the desired siren tone. More the number of built in flash patterns or siren tones in the equipment, better it is for your cause, as you have more options to make use of during emergencies. Both sirens and emergency lighting equipment can be powered by a simple power supply with 10 16V DC rating. The kit includes customised brackets for special law enforcement vehicles too, so that they can be installed with greater ease. Lastly, an important factor for lights and sirens is the switch panel that helps in easily operating different functions.
