Ambulance lights and siren

Types of Ambulance Lights and Sirens

Ambulance lights and sirens are critical elements of any emergency vehicle. They help other motorists identify and clear the way for the ambulance. The sirens are audible devices that produce a loud sound. They are used to alert other road users of an impending emergency. The siren sound is usually distinct and can be heard from a considerable distance. Common siren sounds include wail, yelp, and phaser. On the other hand, ambulance lights and siren are visual signal devices. They come in different types as discussed below.

• LED lights: Light Emitting Diode (LED) lights are some of the most common types of emergency vehicle lights, including ambulance lights. They are popular for their brightness and efficiency. LED ambulance lights come in different colors, including red, blue, and amber. The red lights signal a danger or emergency, while the blue lights are used by law enforcement. The amber lights are used for visibility. In addition to that, LED lights have multiple flash patterns, making them suitable for different environments.
• Halogen lights: Halogen lights are also popular in the ambulance lights sector. They produce a bright white light that is visible even in daylight. Halogen lights are suitable for rural areas or when there is little or no ambient light. They are also cheaper compared to their LED counterparts. However, halogen lights are not very efficient as they can get very hot.
• Strobe lights: Strobe lights are commonly used for their intensity. They produce bright flashes of light that are hard to miss. Strobe lights are highly effective at grabbing attention, especially in heavy traffic or low-visibility areas. They are mostly used in combination with ambulance sirens and other types of lights.
• Rotating lights: Rotating lights are a traditional type of emergency lights. They consist of a rotating mirror that reflects the light from a bulb. These lights are highly visible and can be used in different weather conditions. However, they are not as efficient as they can be mistaken for other types of lights.
• Whelen lights: Whelen lights are a popular brand of lights that are commonly used in emergency vehicles. Whelen lights come in different configurations, including the Whelen Liberty lightbar. The lightbars are popular for their bright and efficient LED lights.

Specifications and Maintenance of Ambulance Lights and Siren

Below are the specifications of the use of lights and siren on an ambulance.

• Wiring

Some sirens come with a plug and play design that enables easy installation without cutting into the vehicle's wiring. Also, the siren might have a wiring harness kit with pre-wired connections. This kit might have all the necessary wires and connectors, which reduces the installation time.

• Siren Tones

Modern ambulances have sirens with various patterns and tones to alert other road users. The tones can be wail, yelp, or phaser. Wail is a rising and descending tone, while yelp is a fast-paced rising and descending tone. Phaser is a high to low pitch tone that rapidly fluctuates.

• Controls

The siren and light controls are usually placed within reach of the driver. They are mounted on the dashboard or the center console. Also, the controls have user-friendly buttons or switches. The switches are easy to operate even when the driver is stressed.

• Amplification

The siren has an amplifier that enhances the volume of the siren. The amplifier is usually powerful enough to be heard from a distance. The amplifier comes with adjustable settings that enable the driver to adjust the volume according to the environment.

• Microphone

Some sirens come with a microphone that enables the driver to make announcements. The microphone is usually noise-cancelling, which eliminates background noise. The microphone also ensures that the message is clear and understandable.

• Speaker

The siren also has a speaker that broadcasts the siren's sound and the driver's voice. The speaker is usually weatherproof to withstand harsh environmental conditions.

Check the lights and sirens regularly to ensure they are functioning properly. Turn on each light to check for cracks, moisture, or burnt-out bulbs. Also, check the siren for any damage or loose connection. This will ensure the siren is working properly. Replace the damaged parts immediately to avoid inconveniences. Consult the manufacturer's guide on how to clean the lights and siren. Use a soft damp cloth to wipe the surfaces and a soft brush to clean the crevices. The cloth will remove the dust particles, while the brush will remove the dirt. Also, avoid using abrasive cleaning materials because they can damage the surface of the lights and siren.

How to choose ambulance lights and siren

Choosing the right siren and ambulance siren light for a particular situation is important. Here are some factors to consider when choosing an ambulance siren and light:

• Regulations and compliance

There are regulations and guidelines that control the use of lights and siren on an ambulance. Be sure to get equipment that fits the local regulations. The type of lights, colors, and how they should be used is specified in the regulations.

• Usage and environment

Consider how the ambulance siren and lights will be used. For instance, consider the environment, whether rural or urban, and the traffic conditions. This will help decide the visibility and brightness of the lights needed. Also, consider the different weather conditions that may be experienced, like fog or rain.

• Visibility and effectiveness

Ambulance lights need to be very visible so that other road users can see the ambulance. For this reason, a light with a high lumen output is required. This will ensure that the light is bright enough to be seen clearly, even in daylight or when it is dark. Pick lights that give a 360-degree view to ensure that they are seen from all directions. The effectiveness and visibility of the siren noise should also be considered.

• Quality and reliability

Ambulance lights and sirens will be used frequently, so it is important to get equipment that is durable and reliable. Look for lights with a rugged design to withstand vibrations and harsh environments. Check the IP rating to find out if the lights can handle dust and water. Also, consider the warranty provided by the manufacturer.

• Ergonomics and installation

Consider how easy it will be to install and operate the lights and siren. Choose lighting that has a simple installation process. Consider the control options for the siren and lights and how easy they will be to use.

• Budget and cost

Set a budget for the ambulance siren light price and stick to it. However, it is important not to compromise on quality to stay within budget. Compare different products and suppliers to get the best deal.
