LED Headlight Bulbs: Are They Legal to Use on the Road? - NAOEVO (2024)

LED headlights have become a popular choice for many drivers due to their energy efficiency, durability, and brighter light output. However, the legality of LED headlight bulbsis a topic of concern for many drivers. In this article, we will explore the legal requirements for LED headlight bulbs in different regions and provide sometips on how to choose LED headlight bulbs without causing glare light to others.

In California, the regulations governing LED headlight bulbs are similar to the federal regulations, but there are some additional requirements that apply specifically to California.

1. Headlight color:As mentioned, car headlights in California must emit a white or yellow light and cannot have a blue tint. The CCR specifically states that “no vehicle may be equipped with a lamp that emits a blue light” (CCR 25600).

In a word, it they are aftermarket upgrades, they should have a white color temperature ranging between 5000K – 6000K and should not be positioned too high or too low from the ground.

2. Headlight brightness and glare:California has regulations regarding the brightness and glare of headlights to ensure that they do not blind other drivers on the road. The CCR specifies that headlights must be aimed and adjusted so that they do not project a glare that interferes with the vision of drivers of oncoming vehicles (CCR 25610). In addition, the CVCrequires that headlights be used in a manner that does not blind other drivers on the road (CVC 24409).

3. Aftermarket LED headlight bulbs:California requires that all aftermarket LED headlight bulbs be marked “DOT” (Department of Transportation) to indicate that they comply with federal regulations. The CCR specifies that any headlight bulb sold or offered for sale in California must meet the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 108, which sets standards for headlight brightness and beam pattern (CCR 25620).

The market for vehicle sales in India is experiencing a remarkable rate of growth, making it one of the fastest-growing regions globally.Some popular cars in India are Maruti Suzuki, Hyundai, Honda, Toyota, and Tata etc. Therefore, in India, is it legal to use white LED headlight bulbs for cars?

The Central Motor Vehicle Rules(CMVR) set out the regulations for vehicles in India, and they allow for the use of LED headlights provided they meet the following requirements:

1. The LED headlights should comply with the specifications prescribed in the Indian Standards (IS) for automotive lighting.

2. The LED headlights should be fitted with a suitable lens that meets the requirements of the CMVR.

3. The LED headlights should not cause glare or dazzle other road users.

4. The LED headlights should be properly aligned and adjusted to avoid causing discomfort or hindering the vision of other road users.

It’s important to note that failure to comply with these regulations can attract penalties and fines. Therefore, it’s crucial to ensure that the LED headlights used in cars in India meet the requirements set out in the CMVR.

The regulation of LED headlight bulbs in the UK is primarily governed by the Road Vehicles Lighting Regulations 1989. These regulations specify the technical requirements for all lighting equipment fitted to vehicles, including headlight bulbs.

In particular, the regulations require that all headlight bulbs must comply with the British Standard BS AU 256:2002, or an equivalent standard. This standard sets out requirements for the performance, construction, and dimensions of headlamp bulbs, including their photometric characteristics (i.e., the amount and direction of light they emit).

Additionally, the regulations require that all headlight bulbs must be properly aimed and aligned to avoid causing undue glare to other road users. They must also be of a specific color temperature and have a specific beam pattern.

If a vehicle is fitted with LED headlight bulbs, it must comply with the regulations set out in the Road Vehicles Lighting Regulations 1989. If the LED headlight bulbs do not comply with these regulations, they may be deemed illegal and subject to enforcement action by the police.

In the Philippines, the regulation of LED headlight bulbs falls under the jurisdiction of the Land Transportation Office(LTO), which is responsible for ensuring the safety and compliance of all vehicles on the road.

The LTO has issued guidelines that specify the technical requirements for headlights, including LED headlight bulbs. These requirements are based on the Philippine National Standard (PNS) and aim to ensure that headlights are safe, effective, and do not cause any unnecessary glare or discomfort to other road users.

According to the LTO guidelines,usingLED headlight bulbsshould comply with the following characteristics:

1. Color Temperature:The LED headlight bulb should have a color temperature of between 4,000 and 6,000 Kelvin (K). This color range provides good visibility without being too harsh or glaring.

2. Brightness:The LED headlight bulb should not be brighter than 5000 lumens. This limit is to prevent excessive glare that can be distracting and dangerous for other road users.

3. Alignment:The LED headlight bulb should be properly aligned to ensure that the light is focused on the road ahead and not blinding oncoming drivers.

4. Certification:LED headlight bulbs should have the necessary certification from the manufacturer, indicating that they meet the PNS standards.

It’s important to note that failure to comply with the LTO guidelines regarding LED headlight bulbs could result in fines, penalties, or even the confiscation of the vehicle. Therefore, it’s essential to ensure that any LED headlight bulbs installed in your vehicle meet the necessary technical requirements to avoid any legal or safety issues.

Despite their energy efficiency, long lifespan, and bright illumination, LED headlight bulbs can also produce harsh lighting that can dazzle other drivers and pedestrians, making them illegal and dangerous to use on the road. Here are three main features of illegal LED headlight bulbs.

1. Non-standard Colors

The OEM car headlights are either white or yellow. However, some LED headlight bulbs on the market may feature non-standard colors like blue, purple, or green. In many places, these colors are prohibited for use on the public roads, as they are difficult for the human visual systems to process. Thus, they often provoke significantly stronger discomfort reactions. By using high color temperature (like 8000K, 10000K) or non-standard colors will be confusing and distracting to other drivers.

2. Incorrect Beam Pattern

Another feature of illegal LED headlight bulbs is that they often have an incorrect beam pattern. The beam pattern of a headlight bulb is crucial as it determines the direction and intensity of the light being emitted. When the beam pattern is incorrect, the light can be dispersed unevenly, creating bright spots, and dark spots on the road. This can be disorienting for other drivers on the road and cause them to lose their sense of direction. This can lead to accidents as well, making it dangerous to use such bulbs.

3. Incompatible with the Vehicle

This means that the LED headlight bulbs do not perform as well as the halogen bulb in the OEM headlight housing. Some LED headlight bulbs are designed with wide space between the two beads, how is that supposed to mimic the original filament of halogen bulb? Besides, some LED headlight bulbs are designed with the long headlamp and large heat sink, making it a wrong position in the headlight housing, resulting in diffuse light.

Other Factors

Other external factors, such as incorrect alignment of LED headlight bulbs, aging headlights and the reflector/projector design of the headlight housing will also lead to the illegal use of LED bulbs.

There are many LED headlight bulbs on the market claim that they are truly street-legal, however, not all LED headlight bulbs are legal for street use. Selecting a legal LED headlight bulb can be a daunting task. Here are some key factors to help you clarify if the LED headlight bulbs you buy are safe.

1. Brightness

Look for headlight bulbs that provide enough brightness for safe nighttime driving. Make sure the bulbs you choose are not too bright or too dim, as they can affect your visibility or cause discomfort for other drivers.

2. Color Temperature

LED headlights come in different color temperatures measured in Kelvins. The temperature affects the color of the light emitted. A range of 6000K-6500K is recommended as it provides a bright and natural white light that is easy on the eyes.

3. Beam Pattern

Consider the beam pattern of the LED headlight bulbs, including their spread and intensity. You want bulbs that provide a balanced and even beam pattern that illuminates the road ahead without blinding oncoming drivers. So what is a good light beam pattern of the LED headlight bulb? More details will be shown in our previous blog: LED headlight bulb beam pattern – all you need to know.

4. Compatibility

Check if the headlight bulbs you are considering are compatible with your car’s make and model. It’s also better to choose LED headlight bulbs that have the same lighting position and size as halogen.

5. Brand and Price

Choose a reputable brandand be prepared to spend a little more for high-quality, street-legal LED headlights.

To reduce glare and improve safety, it is important to choose high-quality, street-legal LED headlights, to install them correctly, and align them properly. Click here to preview our blog about 7 Tips for Choosing the Optimum LED Light For Car.
