SirenWorld just one upped the company I had been going through for emergency equipment for the past three years. Over the course of a day, I was able to get answers from the company owner in regards to a custom piece of equipment. Within 24 hours of bringing up the issue, I was able to place the order in confidence that it would come out as I wanted it to. Not to mention, the quality of parts surpasses the previous company I had been working with. 4W LEDs? There's folks that haven't even whispered about 4W LEDs yet. I am looking forward to receiving my product and will continue purchasing items from SirenWorld.

Emergency Lighting Guide

We are constantly asked "Where should I start?"  "What lights do I need?"... we found this guide to be the most helpful when determining your emergency lighting needs.   This tutorial comes from ELightbars.org which is a forum of the best minds in the emergency vehicle equipment and lighting world.  If you have suggestions, please let us know!

360-degree coverage

All emergency vehicles should have full 360-degree coverage. This is mandated by law many places. The simplest way to achieve this is by using a beacon or full size lightbar. However, a minibar will work just as well in most cases.

360 Lighting

If you drive a tall vehicle, remember that the beacon can be hidden to vehicles close to you, and you may need two beacons diagonally mounted.The same problem applies to minibars and lightbars, so you might need to add some additional lighting.

If you replace the roof-mounted light with interior lights, remember that you still need adequate warning lights facing to the sides.

Also: consider the "viewing-angle" of the light you install: a vertically mounted TIR-style module will give a very narrow "field of view", where as a horizontally mounted linear-style module wil give a much wider "field of view".


When navigating through dense traffic, remember that only a small part of your vehicle may be visible to oncoming drivers.

Since anyone can flash their headlights, it is recommended to also put warning lights towards the corners of your vehicle. The same problem applies from the rear when stationary in traffic. This can be achieved with HAW (hide-aways) in vehicle lights or surface mounted, lights under or on the sideview mirrors, a wide lightbar or decklights in the corners of your windshield. ...to mention some.

Front Intersection Warning

One of the more dangerous situations when responding is navigating intersections, especially red lights or intersections where others have the right of way. If your vehicle is partially hidden by other vehicles, your lightbar or sidemounted warninglights may not be visible, and your siren is pointing forward. Hence, it is recommended to mount some form of outward-facing warninglights towards the front of the vehicle.

This can be achieved with HAW (hide-aways) in vehicle cornerlights or surface mounted on the side of the bumper, outward-facing modules on the license plate or in the grille or on the side of a pushbumper for example.

Avoid flashing or interfering with your turn signals as you ought to use them in communicating with oncoming traffic when driving, even on response (standard curriculum in emergency driving courses)!

Some lights will cover both width and front intersection warning, such as properly places HAWs in vehicle cornerlights or surface-mounted on side of bumper. A very minimal install could look like this: Nighttime low-power option If your vehicle is equipped with a lot of warning lights, it is highly recommended that some or all of these can be turned down during the darker hours, to avoid blinding other drivers.

The idea that blinded drivers will slow down is false!

Some simply carry on, either from stupidity or confusion, and will not be able to see officers in the best of reflective gear. Studies have also shown that drivers tend to skew towards where they are focused. Think of your car: it has driving lights and parking lights, and in driver-education you probably learned to turn off your driving-lights when parked, to allow for other drivers to see the contours of your vehicle and any people or other vehicles next to or behind it. The same applies to warning-lights. DO NOT BLIND OTHER DRIVERS!

Final Pro Tips:

Finally, always check with local regulations and abide by them!  If local regulations require your vehicle to meet a certain standard; comply with it!
