As more and more people owning one or more vehicles, the accident rate starts to rise. In order to warn others, you can have an emergency light installed on your vehicle. Emergency light is one or more visual warning lights installed in the vehicle when the driver wishes to tell other road users the urgency of their journey, to provide additional warnings of danger at rest, or in law enforcement, to signal to another driver to stop for interaction with the officer.

These lights can be called emergency lights, such as beacons, warning lights or mini light bars, or modified stock lighting. Typically, they are used with a siren to increase their efficiency. In many places, the use of these lights may be subject to user-specific legal powers and may require other road users to behave differently, such as forcing them to take roadsides and yields so that emergency vehicles can be carried out unhindered.

Anyone Can Buy Emergency Light, Yet Can Anyone Use?

emergency lightAs a vehicle emergency light retailer, we are often plagued by questions about the legality of our products. The customer asked if the emergency light and siren we advertised were allowed to be used on personal vehicles, which is the complicated problem of the sales of emergency light.

Our emergency lights are available to the public. Yet, not everyone can operate the emergency light on public roads. That means you can buy any emergency light in any color from us. Yet, whether you can use it on public roads in the United States is dictated by state law. Who can and cannot use vehicle emergency lights depends on the written policies which every state in the United States has. Some laws are more lenient than others, but some laws have restrictions on the lights on cars.

Because the regulations vary from state to state, we cannot tell customers if the warning lights they considering is available for use on the roads in their area. Instead, it is responsible for buyers, drivers, and installers to make sure the lights they want to purchase for their vehicles are used legally in the state they plan to operate. To ensure that customers understand the regulations of emergency light in their states, we recommend that anyone considering purchasing lights from our online store be familiar with their state laws before purchasing.

Emergency Lights for Off-Road and Private Use are Allowed

In fact, emergency light can be allowed to use on vehicles when you need to use them for off-road and private use. In this case, farmers and private security firms are the biggest client base. Farmers may want to put warning lights on their ATV, tractors and farm vehicles for use on framing. Security agencies that patrol private places such as company parking lots, amusement parks, private entertainment venues, and shopping malls may need to install warning lights on vehicles. When such types of customers purchase warning lights, they mainly use the warning lights to help inspect private property. Due to most state regulations apply only to use on the road, the law does not prohibit drivers from using emergency lights on private land. They can use the LED warning lights in their private property freely.

Usage & Colors Vary From Country to Country

It is important to note that the color and the placement of the emergency light vary in different places. Even in the US, different states would have different rules for vehicle emergency lights. In the US, red is believed to be easier to see in the daytime; blue is better seen at night. However, they are not the only color you can choose. Purple, green and amber/yellow can also be used in some states in the US.

Color Options

warning lightsIn many places, the green light is considered a courtesy light, which means that the vehicle is requesting access when exercising emergency vehicle lights, rather than requiring access. In some states, volunteer firefighters are allowed to use green light instead of traditional red and white lights used by fire departments across the United States. When a volunteer firefighter uses a green light on his personal vehicle, the state’s law treats the device as a courtesy light. Since the unit is not considered as an emergency light, the state’s laws may not apply to this situation.

The amber warning light is the least restrictive warning light color in the United States. It means that most states allow yellow warning lights for various vehicles. However, state law still stipulates when this type of lighting can be used. For example, in Ohio, a construction vehicle or utility company vehicle can use an amber light while parked on the side of the road. Yet they cannot use a warning light while the vehicle is driving.

Purple warning lights are very rare on roads nowadays. Some emergency vehicle light retailers don’t even sell this type of equipment because it is not popular. States that allowed using purple in vehicles are usually restricted to use the purple emergency lights by funeral procession vehicles.
