The harsh glare of LED lights can be particularly problematic for drivers who are already experiencing vision loss or have other visual impairments.
The Rise of LED Lights in Cars
In recent years, the automotive industry has seen a significant shift towards LED lights in vehicles. LED lights are energy-efficient, long-lasting, and offer improved visibility. However, their increased brightness can be a concern for other drivers.
Safety Concerns
The Impact on Drivers with Visual Impairments
Drivers with visual impairments, such as those with macular degeneration or cataracts, may find the harsh glare of LED lights particularly distressing.
By 2020, the use of LED bulbs in daytime running lights had become widespread, with over 90% of new car models featuring LED daytime running lights.
The Rise of LED Daytime Running Lights
The use of LED daytime running lights has become increasingly popular in the automotive industry over the past two decades. This trend can be attributed to several factors, including advancements in technology, environmental concerns, and changing consumer preferences.

Changing Consumer Preferences
LED lights are also more expensive than traditional incandescent bulbs.
The Benefits of LED Lights
LED lights have several advantages over traditional incandescent bulbs. Here are some of the key benefits:
The Impact of Streetlights on Rural Towns
In rural areas, the lack of streetlights can have a significant impact on the quality of life for residents. Unlit roads can lead to increased risk of accidents, as drivers may not be able to see pedestrians, animals, or other vehicles. This can be particularly problematic at night, when visibility is already reduced. The lack of streetlights can also exacerbate the effects of glare, making it difficult for drivers to see the road ahead. In addition, unlit roads can lead to increased wear and tear on vehicles, as drivers may be forced to slow down or stop frequently to navigate through dark areas. Furthermore, the lack of streetlights can also have a negative impact on local businesses, as customers may be deterred from visiting areas with poor lighting.
The Cost of Streetlights in Rural Towns
The cost of installing and maintaining streetlights in rural towns can be prohibitively expensive. Many rural towns have limited budgets, making it difficult for them to afford the upfront costs of installing streetlights. The cost of installing a single streetlight can range from $5,000 to $20,000, depending on the type and quality of the light. Additionally, the cost of maintaining streetlights can be significant, as they require regular cleaning and replacement of bulbs.
The Problem of LED Lights on Uneven Roads
In the United States, the use of LED lights in vehicles has become increasingly popular due to their energy efficiency and long lifespan. However, this trend has also led to a problem that affects road safety: the uneven distribution of light from LED headlights. When an LED light is mounted on a vehicle, it can create a “hot spot” of extremely bright light on the road ahead, particularly on uneven or curved surfaces. This can be a significant hazard for drivers, as it can cause glare and reduce visibility.
How LED Lights Affect Road Safety
The Science Behind the Problem
The problem of LED lights on uneven roads is largely due to the way these lights are designed and mounted. LED headlights are typically mounted at an angle to the road, which can cause the light to be focused onto a specific point on the road. This can create a “hot spot” of extremely bright light, which can be particularly hazardous for drivers.
The Impact of Blue Light on Drivers
Blue light, a high-energy visible (HEV) light with a wavelength of around 400-450 nanometers, has been shown to have a significant impact on drivers. The effects of blue light on the human eye are multifaceted, and its effects on driving are particularly concerning.
The Science Behind Blue Light
Blue light is emitted by digital devices such as smartphones, tablets, and computers, as well as by LED lighting in cars. It is a form of electromagnetic radiation that can penetrate the eye and cause damage to the retina. The retina is a complex structure that contains specialized cells called photoreceptors, which convert light into electrical signals that are transmitted to the brain. The photoreceptors in the retina are sensitive to different wavelengths of light, with the blue-violet end of the spectrum being particularly sensitive to damage. Prolonged exposure to blue light has been shown to cause a range of effects, including:*
- Disruption of the body’s natural circadian rhythms
- Increased risk of macular degeneration
- Digital eye strain and fatigue
- Impaired night vision
The Effects of Blue Light on Driving
The effects of blue light on driving are particularly concerning, as it can impair a driver’s ability to see at night. Blue light can cause the following effects:
Texas Headlight Laws: A State-by-State Approach
Overview of Headlight Laws in Texas
Headlight laws in Texas are governed by the state’s Department of Public Safety (DPS) and are based on the federal standards for headlight brightness. However, some states have started introducing guidelines that differ from the national standards. In Texas, headlights must merely cast a white light and cannot be obscured by a cover or grill.
This lack of compliance led to a number of safety issues, including accidents and fatalities.
The Need for Improved Safety Features
The lack of ADBs in the US market has been a concern for many years. In 2022, the National Highway Traffic Safety Administration (NHTSA) finally approved the use of ADBs in the US. However, the approval came with a condition that the systems must meet specific brightness standards. This condition has led to a number of manufacturers opting to delay the implementation of ADBs in their vehicles.
Benefits of ADBs
The Impact of the Proposed Bill
Rep. Sabadosa’s bill aims to address the lack of ADBs in the US market by requiring all cars sold in the state to have the systems.
However, the federal government has the authority to regulate the safety of headlights.
The Rise of State-Level Regulation
The United States has long been characterized by a federal system of government, where power is divided between the federal government and individual states. However, as the country continues to evolve, it is becoming increasingly clear that this system is no longer sufficient to address the complex challenges facing the nation. One area where this is particularly evident is in the realm of regulation.
The Federal Government’s Inadequate Response
The federal government has struggled to establish and enforce a unified national standard for various industries and sectors. This lack of coordination has led to a patchwork of regulations, with different states imposing their own rules and standards. While this may seem like a minor issue, it has significant implications for businesses, consumers, and the environment. The lack of a unified national standard can lead to confusion and uncertainty for businesses, making it difficult for them to navigate the regulatory landscape. Consumers may also be affected, as different states may have different rules and standards for products and services. Furthermore, the lack of a unified national standard can hinder efforts to address environmental and public health concerns.
The Rise of State-Level Regulation
As the federal government continues to struggle to address these challenges, individual states are taking matters into their own hands. Soon, states will begin to establish their own standards and regulations, a move that is likely to have significant implications for businesses, consumers, and the environment.
