Buyer's Guide: Warning Lights

Buying Guide: How to choose the right Warning Lights

Warning lights are essential for a variety of reasons. Whether you're a truck driver, a pilot, or a delivery person, you'll need to know the right warning lights. Warning lights can warn other drivers that you're turning, and they can tell other drivers your stopping distance and can even be used to signal other vehicles in the event of an emergency. In this article, we will cover some of the most common warning lights and what they mean.

What are Warning Lights?

Warning lights are lights on your vehicle that indicate that there's something that needs your immediate attention. These lights can indicate that a car is about to back over another car, that you need to brake suddenly or change lanes, or that a truck needs to stop, for example.

A driver should always have the front brake on if you attempt to brake suddenly, change lanes, or turn. However, if there is another vehicle in front of you, you may want the passenger brake instead.

Different types of warning lights

There are a variety of warning lights, and they all serve a similar purpose. In the case of each of the different types of warning lights, there are different purposes. As always, it's essential to know your role. Some warning lights are only applicable to specific situations, while others are best for all situations. Keep in mind that some warning lights have more than one purpose, but in general, you can use the term "warning" light to refer to any indicator attached to the driver's side of the vehicle.

What's the difference between Yellow, Red & Green Warning Lights?

Warning lights come in three primary colors – yellow, red, and green. Each warning light has its meaning and purpose. The red light usually means your vehicle is stopped, and the green light means that it is not safe to drive. Yellow lights have a completely different meaning – they're used as a warning for heavy vehicles. It means that if you have your vehicle's low range switch set to the yellow light, this means you're to slow down and turn your vehicle's headlights off. Yellow warning lights can alert drivers that they're turning, they can alert other drivers that your stopping distance is less than the legal limit, and they can even be used as an emergency signal.

Things to consider before purchasing warning lights

If you want to buy warning lights for your car, make sure you are not buying them for the wrong purpose. For example, if you are buying warning lights for your car to warn other drivers that you are about to turn, that is probably not the best purchase because this warning is not directed at other drivers. To get your warning lights to work correctly, you need to have one for each side of your vehicle. You also need to be aware that certain warning lights may require the installation of additional warning lights because the type of warning light you need may change depending on the car you have.


When compared to traditional incandescent lamps, LED lighting is five times more energy efficient. Compared to standard incandescent lamps, it has a longer lifespan and is more durable. LED lights have an energy consumption range of 2 to 10 watts.


Brightness refers to the brightness of the lights used on a vehicle. Most warning lights on vehicles have a maximum brightness of 200 Lumens. For comparison, a typical traffic signal has a maximum brightness of 30 Lumens.

Instead of actual red light, you will typically see a regular traffic signal light, also known as a "non-illuminated red light." These lights emit red light but can also have a flashing yellow light that flashes between three and ten seconds, depending on the configuration.


Most warning lights are round, flashing, and vibrating. There are numerous designs and forms to choose from. Some are small enough to fit through your windshield, while others resemble a massive red and white bubble. The compact size of LEDs allows for the design and fabrication of objects and technologies previously challenging to achieve with other materials and technologies.

LED lights generally are the most common warning lights, as they use a few simple components, such as a semiconductor diode. These small circuits can provide a lot of lighting and are much smaller and lighter than the standard fluorescent bulbs with a standard car. For this reason, LED lights are generally installed most cost-effectively. While some standard warning lights work with standard bulbs, it is much less common to see an LED driver at the speedometer.


Turning the wheel with the engine off puts power into the batteries, and since many modern cars no longer have ignition crankshafts, you can no longer start the car. If you're driving an older model car, you can power it up by driving the engine forward with the lights turned off. Don't expect the car to start up on its own, though; the car has to be able to crank the engine up on its own.

If you're driving a large car, it might be possible for you to turn off the engine by pulling on the parking brake lever (usually, the keys will be in the ignition) and turning the steering wheel to the right, and cranking the wheel to the left.

Coolant Temperature

Coolant Temperature (CT) gauges are among the most commonly used warning lights. They tell drivers how much coolant is in the radiator so that they can perform an important function: overfilling the radiator will cause the radiator to heat up.

The amount of coolant in the radiator is calculated by taking the thermo-hydraulic pressure and dividing it by the coolant volume. The thermo-hydraulic pressure is a measure of the amount of heat generated by the cooling system. This pressure is highest when the coldest system begins to decrease as the engine temperature increases. Since the radiator is placed directly behind the combustion engine, the highest thermo-hydraulic pressure occurs when the engine is coldest.

How to choose the best Warning Lights for your specific needs

Before you shop for your first warning lights, it's essential to understand. Many options come in various shapes and sizes, which can make choosing suitable warnings difficult. Make sure you don't buy the first warning light you see, but instead, learn what you're looking for and don't settle for the first warning light you're offered.

Then decide whether you want lights to indicate high-speed and hard braking or low-speed low-braking and siren use. Some LED lights can flash, some can turn on with a beep, and some can be with both. Some LED lights are designed to serve a warning light function, while others will work as a visual indicator. They all have a place in your car, and you need to know what they're needed.

Final thoughts

Your car is the first thing most people notice. In an emergency, you must know precisely what warning lights mean and how they are meant to be used. In the case of a safety issue, it can mean the difference between life and death.
