Truck lights are essential for making trucks visible, especially in poor weather or low-light conditions. They mark the truck’s presence, helping other road users notice the vehicle’s size and location.?Navigating such large vehicles is no easy task for OTR truck drivers, and good lighting is crucial for their safety and the safety of others. This is why investing in high-quality lights, like LED marker lights, fog lights, and headlights, is so important—they not only enhance visibility but also ensure smoother driving experiences in various conditions. However, purchasing lights for your truck involves more than just picking out powerful bulbs. Federal and state regulations govern the types of light used on trucks, meaning not all lights are legally permissible.?
If you equip your vehicle with non-compliant truck lights, you could face penalties such as fines or being forced to remove them. For instance, while some aftermarket lights might be visually appealing or offer extra brightness, they might need to meet the legal requirements for trucks on public roads.
To avoid these costly mistakes, it's essential to research relevant regulations before investing in any lighting upgrades. Doing this homework ensures that your truck lights will serve their functional purpose and comply with laws, saving you from potential trouble down the line.?
In the next section, we’ll discuss what you need to know about these regulations and provide expert advice on selecting the best lights that meet your needs and legal standards. This way, you can make an informed decision while keeping your rig safe and compliant.
Federal guidelines for truck lights
Truck lighting is governed by two major federal agencies: the National Highway Traffic Safety Administration (NHTSA) and the Federal Motor Carrier Safety Administration (FMCSA).
For newly manufactured trucks, NHTSA regulations are outlined in section 571.108 of the Federal Motor Vehicle Safety Standards (FMVSS). FMCSA regulations, found in section 393.11, focus on trucks already in service. Both sets of rules are closely related, with the FMCSA requiring tow trucks to maintain compliance with the FMVSS standards that were in place when the vehicle was built.
The basic lighting requirements for trucks include headlights, brake lights, turn signals, backup lights, and side and clearance lights. Reflectors must be installed at the vehicle's corners to enhance visibility. Some lights, such as headlights, can serve multiple purposes, including acting as clearance lights.
For trucks over 30 feet long, additional side marker lights and reflectors are required near the midpoint. Trucks wider than 80 inches must have three identification marker lights on the front and back to signal their larger size.
State guidelines for truck lights
In addition to federal laws, truck operators must comply with their state’s specific lighting regulations, which can vary. You can check the rules in your state through local law enforcement agencies.
Several aspects are commonly regulated by states, including:
Staying informed on federal and state lighting regulations is crucial to ensuring compliance, preventing fines, and guaranteeing road safety.
9 types of truck lights and their functions
Each type of light serves a unique purpose, enhancing the truck’s presence and functionality in different driving conditions. Here is a breakdown of the most important truck lights and how they work.
Tail lights are located at the truck's rear and ensure the vehicle’s visibility to other drivers. They automatically turn on when the headlights are activated and prevent rear-end collisions. Tail lights generally include:
Headlights are critical for providing visibility in low-light conditions, such as at night, during fog, or when it’s raining.
Marker lights are smaller lights positioned along the truck’s sides, front, and rear. Their primary role is to improve the truck’s visibility, especially in dark or poor weather conditions. Marker lights make it easier for other drivers to see the truck's full size, preventing potential collisions.
Fog lights are located lower on the front bumper and help the driver see the road during fog, rain, or snow. Their placement reduces glare and helps maintain visibility in conditions where regular headlights may not be as effective.?

Spotlights and floodlights provide additional lighting for specific tasks, such as loading or unloading at night.
Daytime running lights are low-power lights that remain on during the day to increase the truck’s visibility. These lights are particularly useful during bright daylight or in cloudy weather, reducing the risk of accidents by making the truck more noticeable.
Auxiliary lights are additional lights that can be installed on a truck for specific purposes like off-roading or working at night. These include driving lights, off-road lights, and work lights, offering extra visibility in unique driving conditions or for nighttime tasks.
Interior truck lights are used to illuminate the cabin and are helpful for nighttime driving. They allow drivers to read maps, check gauges, or locate items without straining their eyes in the dark.
Underbody glow lights are typically used for decorative purposes. They illuminate the area beneath the truck, adding a visual appeal, especially during night drives, though they do not serve any functional purpose for driving safety.
LED vs. halogen lights: which is better?
When comparing LED and halogen truck lights, both options offer distinct advantages and disadvantages depending on cost, efficiency, and intended use.?
LED lights are more energy-efficient, offer better brightness, and tend to last longer than halogen lights. Their superior illumination makes them ideal for night driving or bad weather, though they are more expensive and may require specific installations.
On the other hand, halogen lights are a more budget-friendly choice and are easy to replace. They’re widely available and simple to install, but they don’t last as long and aren’t as energy-efficient as LEDs. Moreover, halogen bulbs provide less intense light, which can reduce visibility in darker conditions.
For truckers who frequently drive in low-light conditions, investing in LED lights can offer increased safety and longevity despite the higher initial cost. Halogens, while more affordable, might not be the best choice for drivers needing enhanced nighttime visibility.
Customizing your truck lights
Many truckers personalize their vehicles with unique lighting to improve their style. Though customization is exciting, truckers must follow local regulations regarding lighting, as some colors, like red and blue, are restricted to emergency vehicles in certain regions. Therefore, it's crucial to balance personal style with legal compliance when modifying truck lights.
On a budget? Consider these costs?
The initial investment can seem significant when upgrading your truck lights, especially if you opt for modern lighting technologies like LEDs. These lights often cost more upfront than traditional halogen or xenon bulbs.?
However, while the immediate expense may be more significant, the long-term financial benefits far outweigh the initial cost. One of the biggest advantages of LED lights is their energy efficiency. LED truck lights consume much less power than halogen lights, which reduces strain on the vehicle’s electrical system and leads to fuel savings over time. This can be especially important for truck drivers who spend long hours on the road, as lower power consumption reduces overall operational costs.
LED lights are also far more durable than their halogen counterparts. Traditional lights tend to burn out quickly, particularly in harsh weather conditions or after long periods of use. Frequent replacements and repairs of halogen bulbs can add up to a considerable expense over time. LEDs, by contrast, are designed to last much longer, with lifespans extending to tens of thousands of hours of use. This long-lasting performance reduces the frequency of replacements, saving money on parts and labor. This durability for truckers or fleet operators translates into fewer disruptions and a lower long-term maintenance budget.
While LED lights require specialized installation in some cases, which can increase the initial cost, the energy, maintenance, and safety savings make the investment worthwhile over the long term. Truckers committed to improving their vehicle’s efficiency and longevity will find that upgrading to LED lights is not only a smart decision but also a financially prudent one. The initial expense is easily offset by the benefits they provide, making LED lighting systems an essential consideration for anyone looking to enhance their truck's aesthetics and functionality.
