When it is a matter of selecting Police lights and sirens, one has to be additionally careful. Modern lights and sirens come with several advanced features that offer greater versatility and excellent resiliency. When you are choosing lights for emergency vehicles you need to check whether Generation III LED technology is used, as it can offer excellent reliability and great efficiency when it comes to emergency lighting. LEDs are used increasingly instead of incandescent lights and xenon lights because of their extreme lifespan exceeding 40,000 hours in most cases. The light emitting diodes are known for their energy efficiency as they can provide high intensity beams with small currents of 1 -3 Amps generated by a simple 12- 24V DC power supply.

Pattern control is another feature that you need to look at when you purchase Police lights and sirens. In-built flash patterns are provided in police lights which can be altered based on the requirement. You must also check for blackout and dimming options which allow you to utilize the emergency lighting when required and turn them off when not required. In fact, ...
... clear lenses are absolutely undetectable when they are turned off. When required the same lenses can be used to enhance the penetrative power of the beam especially in hazy conditions. When used in conjunction with colored filters, these lenses will enhance the effectiveness of the light beams.

An important aspect of Police lights and sirens is their reliability. It should be possible to mount them easily both in the front as well as in the back of the vehicle. Special rocker switches are provided with emergency lights and sirens in order to alter the flash as well as the siren sound patterns depending upon the need. For example, with the help of rocker switches one can use wail, yelp, two-tone, HiLo and air horn patterns. Similarly, for the lights the flashing can be varied and increased up to 120 flashes per minute. So, ease of installation and mounting, versatility in use and operating control are some of the features which are critical to the effective use of lights and sirens used by emergency vehicles. Given that they might be used under all weather conditions, they should be tough and rugged and should be dust, vibration and wind resistant along with being waterproof.

The attention grabbing ability of the Police lights and sirens is also extremely important. The lights and the sound of the siren should be able to reach out to everyone, even in bad traffic and heavily congested conditions. Alternating flashes of various colors, combined with high wattage speakers can help in sending across the emergency or cautionary message to everyone around. There are light bars designed for wide angle coverage and for 360 degree visibility. Similarly, sirens come with speakers and amplifiers to enhance their effect and make them more useful. The emergency lighting and siren systems are also very compact and hence consume lesser space. They can be mounted on the roof, on the dash board or in the rear end of the vehicle too.
