Fog lights are mounted under the front bumper and behind the rear bumper. They are intentionally positioned slightly inside the vehicle’s body to prevent the light from shining upwards and producing a glare during bad weather.
Fog lights are separate and independent from the headlights. They complement the vehicle’s standard lights, lighting up the area in front, just below the fog.
Most fog lights emit yellow light, though, in modern vehicles, they have a white light.
The beam is rectangular to cover a wider area horizontally. The lamp has a deflective body, focusing the light straight down towards the road.
Rear fog lights give off a red light and have no deflector. They indicate where we are to drivers behind us without being distractive.
Under normal weather conditions, fog lights shouldn’t be in use. They are actually prohibited in some states. This is because vehicle owners tend to switch the manufacturer’s fog lights for others with bright, multi-directional white lights.
When to Switch on Fog Lights
Fog lights are specifically designed for conditions where:
The fog is very thick, posing a danger
Instances where the visibility is very low such as smoky, dusty conditions
They are appropriate for use when we need to see the roadside not illuminated by headlights
On winding roads or immediate corners
Since they can appear similar to brake lights, it’s advisable to use them only when we can’t see beyond 100 meters.
Frequently Asked Questions
Should I Flash My High-Beam Headlights if Another Driver Doesn’t Dim Theirs?
It’s not advisable to flash our high-beam headlights regardless of the other driver’s behavior. The message we intend to communicate by flashing our lights is open to misinterpretation. Some people may think we are rude, angry, or trying to warn them of an accident behind us.
Are Fog Lights and Low Beams the Same Thing?
No. Fog lights are independent and are only present in certain vehicles since they are not a legal requirement. Both high and low beams are part of the headlights, which are on the front bumper.
Is it Legal to Drive with Fog Lights On?
Well, technically, it’s legal to drive while our fog lights are on. However, the light they project should be within the acceptable range to avoid distracting other drivers.
Can I Use Fog Lights When it’s Raining Heavily?
Yes, fog lights are great for rainy conditions. They complement the headlights and help to minimize the glare from your headlights. Avoid them in light rain as they can affect other drivers’ ability to see.
Can I Use Fog Lights Instead of Headlights?
Although fog lights are often used together with headlights, it’s not advisable to use fog lights in place of the headlights. However, in emergencies, it’s okay to use them.
Is it Legal to Use LED Fog Lights on the Road?
Legally, it’s okay to use LED fog lights on the road. However, this largely depends on the direction towards which the light gets aimed.
The type of bulb in use is not the issue, but it can have a legal impact when mounted the wrong way. If the light projects farther than the specified legal field of vision, it will affect other drivers, posing a safety risk.
If my vehicle initially has no fog lights, I can have them mounted. The lights should be about 10 inches to 224 inches above the ground. They should also be below my regular headlights.
How Far Should Fog Lights Shine?
There is no specific distance that the light emitted by fog lights should cover.
