What are Headlight Laws and How they Can Affect You
Headlights are a crucial component of your car that directly impacts driving safety. The right type of headlights helps ensure clear visibility in low-light conditions for a safe driving experience. Any flaw in the car lighting system can put you and other drivers at risk of accidents. It’s the reason headlight laws are made strict, and non-compliance leads to serious action.
Headlight laws are the rules and standards set to govern the production, application, and usage of car headlights. The authorities have set standards that guide manufacturers to produce headlights with specific features for driving safety. These can range from color temperature, beam patterns, and brightness levels.
There are also specific rules for drivers to comply when installing and using headlights on public roads. The rules include guidelines on what type of headlights are road-legal, i.e., HIDs, Halogen Bulbs, and LEDs. Besides that, the restrictions on changing headlights with aftermarket options or getting them tinted. All of these regulations pertaining to headlights impact the drivers.
Non-compliance is a safety risk that can make you susceptible to accidents. The law enforcement is strict and can lead to legal action. The fines for violating headlight laws range from $50 to $500. If you’re a repeat offender, they can impound your car. In the worst-case scenario, you can get your license suspended.
Headlight Laws in the US.
Headlight laws in the US are implemented by federal and state regulatory bodies. Here are the key regulations that you should comply with to avoid inconvenience on public roads. These laws are designed for your and other safety.
FMVSS (Federal Motor Vehicle Safety Standards) Section 571.
The FMVSS are regulations for design, development, performance, and durability requirements for automobiles in the US. Section 108 of FMVSS specifically outlines regulations for lamps, reflective devices, and associated equipment. It covers headlight brightness, beam patterns, angle alignment, and durability.
DOT (Department of Transportation) Compliance
DOT (Department of Transportation) acts as a regulatory body that ensures compliance with FMVSS 108 standards. They are responsible for the inspection of vehicles for their on-road safety. The manufacturers are instructed to mark their headlights DOT-compliant for use on the US roads. If your headlights are not DOT-compliant, you can’t drive with them.
NHTSA (National Highway Traffic Safety Administration) Regulations
NHTSA (National Highway Traffic Safety Administration) is an enforcement agency that checks and regulates the sale of headlights in the US. It also monitors the development of new headlight technology. The objective of NHTSA is to ensure vehicle safety to reduce accidents. It operates under the Department of Transportation (DOT).
What Are DOT-Approved LED Headlights
There’s been a huge buzz around DOT-approved LED headlights. DOT is an acronym for “Department of Transportation” that ensures compliance with Federal Motor Vehicle Safety Standards Subsection 108 (a federal law stating guidelines for car headlights). The headlights you’re using in your car must be DOT-approved, which means they comply with FMVSS 108.
Manufacturers mark their headlights with DOT–approved signs. It means the headlights check all the requirements of the department of transportation. Whenever your car goes for inspection, it will be passed without any reservations related to headlights. DOT-approved is a manufacturer’s way of saying that the headlights are legal for use on US roads.
You should remember that DOT itself doesn’t approve any product. It is a requirement for manufacturers to comply with headlight standards.
Difference between Aftermarket LED Bulbs and OEM Headlights
Understanding the difference between aftermarket LED bulbs and OEM (Original Equipment Manufacturer) headlights is critical. You can’t use aftermarket LED bulbs unless they’re DOT-approved. Here’s how you can identify OEM headlights:
What are OEM Headlights?
Original Equipment Manufacturer (OEM) headlights are the headlights that the manufacturer installed in your car. In case your car headlights are damaged, you can’t just buy any headlights from the market; you need to get the same headlights from the manufacturer. The reason is to avoid compatibility issues and meet regulatory standards.
What are Aftermarket Headlights?
Aftermarket headlights are manufactured by third-party manufacturers apart from the ones that originally manufactured your car. It’s like getting a random mobile charger for your iPhone from any retailer. Aftermarket headlights can have performance and legality issues. They may not comply with headlight laws or have substandard quality.
Understanding the Difference
OEM headlights strictly adhere to FMVSS 108 standards and are designed specifically for your vehicle. Aftermarket headlights may not be manufactured according to regulatory standards. The major concerns in aftermarket headlights are varying brightness levels, glare issues, and misfits in the existing LED housing of your car. However, the customizability in aftermarket headlights is next-level.
Regulations on High Beams, Low Beams, and Fog Lights
There are specific regulations on brightness limits and beam patterns of high-beam & low-beam headlights, and fog lights. Let’s explore:
| Light Type | Brightness Limit | Beam Pattern | Other Restrictions |
|---|---|---|---|
| High Beams | The brightness limit for high beams is 3600 Lumens with a max through of 500 feet. | High beam spread light in a straight direction for maximum visibility | You can’t use high beams in urban areas or when approaching other vehicles |
| Low Beams | Low beams cannot exceed a brightness level of 2400 lumens | Low beams are angled downward and spread on the sides of the road. It also helps avoid blinding oncoming traffic | The standard color for low beams are amber or white |
| Fog Light | The maximum output for fog lights is around 3000 lumens to ensure visibility in foggy conditions. | Fog lights are also angled downward but with a horizontal spread to provide visibility in foggy weather. | Fog lights are restricted to use in clear weather and must be mounted below the headlights. |
Legal Guidelines on Headlights Hues and Shades
The FMVSS 108 has determined a color temperature range for headlights, any shade within the range is legal. Your car headlight temperature should be within the 2500K to 6000K range. The output within this range falls into three color categories: yellow, amber, and white. If the headlight temperature exceeds the 6000K limit, it will be illegal to use.
These headlight colors provide good visibility and don’t affect the human vision. Color temperatures above 6000K tend to produce more glare that can blind oncoming traffic. Most people prefer a color temperature above 6000K due to the bluish effect in the light that looks aesthetically pleasing. However, it’s illegal and can get you pulled over.
The headlight type also affects the brightness level and color temperature. Traditional halogen bulbs emit a warm yellow light within the 3000K to 4300K range, whereas LEDs produce bright white light within the 4000K to 6000K range. The brightest light output is from HIDs that can go beyond the 6000K temperature limit and emit a blue or deep purple light.
Are Colored Headlights Road Legal
Regulations on color headlights are very strict. Any headlight color apart from white or yellow is restricted for public roads. The law has designated three colors, blue, red, and green, for emergency vehicles. It helps avoid confusion among drivers; as a responsible citizen, every driver is bound to make way for emergency vehicles.
Changing headlight colors is not practical. People choose to change the headlight color for aesthetics only. But it’s illegal and can lead to profound implications like fines and vehicle impoundment. Ensure that your car headlight’s color temperature is between 2500 to 6000 kelvins and emits white or amber light.
Headlight tinting to change the color is also prohibited because it reduces brightness levels, which affects visibility. In some US states, the laws on headlight tinting are flexible, but you still need to comply with FMVSS 108 standards. Any tint above 5% will affect the brightness level and decrease visibility.
Things to Consider When Buying Vehicle Headlights
