The Best Underhood Work Lights For 2023

You might need to go under the hood of your vehicle to change the serpentine belt, replace spark plugs, and perform other operations. What makes it even more challenging is the low-quality light.

Whether you are a professional mechanic working at an automobile repair shop or a car owner, chances are you are going to need high-quality underhood work lights to repair the motor or fix some regular issues. Sometimes, it gets nearly impossible to illuminate the engine and other tricky areas that are almost invisible to our eyes.

That’s why many mechanics and car owners store an underhood work light to illuminate the hard to reach or invisible spots in their vehicle.

Despite being smaller in size, the underhood lights produce a considerable amount of light, which is enough to have a clear picture of the car parts.

They are especially recommended for mechanics who work in poorly-lit garages.

What is Underhood Work Light?

Underhood lights are not only for the mechanics and automobile repair specialists. In fact, this light is a great tool for those who need to repair the hard-to-access parts in their vehicle (mostly the motor and parts located underneath your car). Now, the best feature of these lights is their portability. Not only does it make it easier for the car owner to store and carry them, but their compact design enables you to fit these lights anywhere you want.

Underhood work lights are mainly needed in emergencies, such as blackouts. Overall, these lights are extremely useful to illuminate the hard-to-reach parts. As mentioned before, underhood work lights might be small and compact but they deliver a sufficient amount of light. One safety tip to consider when using these lights is to avoid touching them. Just like how you never touch the bulbs in your home, the underhood work light is no different. Furthermore, make sure you attach the light securely to the car. There is a good chance the bulb will break if it falls.

Double-check the magnets, hook, and extendible arms to ensure that the light is fixed firmly. Now, different types of underhood work lights are available on the market. Before you pick the best one, consider a few important factors such as the run time, brightness, build quality and materials, weight, and more. We will discuss these features later in this post.

Factors To Consider When Shopping For Underhood Work Light

Even if you work in a well-lit garage, you are going to face some issues when working under the hood. Inadequate light can result in damages and costly mistakes. Well, no need to worry. The underhood work lights can help you illuminate almost every space.

Each work light comes with a different price. Some offer a better run time than others. Likewise, some lights are more portable than their counterparts. With plenty of options available on the market, the decision of buying the best work light can be quite overwhelming for mechanics. To help you make the best decision, here we have listed a few important features you must take into consideration when shopping for underhood work light.

Build Quality

The first and most important factor is the build quality or construction. This includes the quality of the bulb as well as the material that houses the LED. The construction needs to be strong enough to resist wear and tear. LED light that features low-quality plastic will not last long. Moreover, poor quality materials mean the bulb is prone to damage if it slips from your hand.


Obviously, you can hold the handheld light for as long as you want. However, you will need someone to hold the light for you so that you can focus on repairing the damaged parts. If you need these lights for hours, then you need to fit it somewhere. Choose the lights that can be mounted easily. The best lights are the ones that feature a strong magnetic base, which enables you to attach them to the side of your car or underneath the vehicle securely.

Some underhood work lights feature mounting hooks. Hooks are a great option for those who need to use the work lights for regular repairs.

Run Time

Not all underhood work lights are portable and compact. The corded lights can be super annoying. Remember that you are buying underhood work light to access the areas that are almost invisible. This means you might need to fit the light underneath your car to access the motor, battery cable, control wire, and other parts. The run time of a bulb depends on lumens. The brighter the bulb, the more battery it will drain. Some bulbs come with a battery that lasts for up to 6 hours.

Cordless work lights are extremely convenient. You can fix them anywhere you want without having to deal with the annoying cords. However, cordless lights do not have a good run time. A corded underhood light can work infinitely. But, that is not possible with a cordless light. So, it is important to check and compare the run time, size of the batteries, convenience, and portability before making a purchase.


The main purpose of buying an underhood light is to get adequate light so that you can replace the damaged part or make necessary repairs in poorly-lit areas. A high-quality bulb will deliver sufficient light – no matter where you use them. As much as a bright work light is important, the light should not be too bright to strain your eyes. A light that illuminates the hidden car parts will do. No need to go for extraordinarily bright lights.

The brightness of an LED or bulb is determined by its lumen count. The higher the lumen count, the brighter the light is. If you are looking for a bulb with an average brightness, then 350 lumens is the best option. You will also find the bulbs that deliver up to 1000 lumens. It is best to consider your workstation and choose a normal and adequate level of brightness

Battery Level Indicator

The batteries that need to be charged must also feature a battery level indicator. This tells you the remaining battery percentage and how long you need to charge the bulb. Make sure that the product you choose features a battery level indicator so that you know when the LED needs to be charged.

Waterproof and Dustproof

Nowadays, manufacturers have started designing water-proof and dust-proof lights. Considering the fact that water and dust happen to be the two major causes of most of the issues in electrical appliances, it is best to purchase a waterproof and dustproof bulb. The IP65 lights are waterproof. The IP67 lights, on the other hand, offer full security against water and dust. Even if it is submerged in the water, it will stay unharmed.

Waterproof and dustproof bulbs tend to last longer than standard lights. They are especially needed if you are working in a garage.


Last but not least, the budget is an important factor to consider when investing in underhood work lights. Remember that the price of a work light depends on the quality of materials used for its construction. So, the better the quality of the product, the higher its price will be. It doesn’t mean you should buy the most expensive work lights. Set your budget and find a light that matches your preference. But, don’t stick to your budget. If you need to spend a few more bucks for a high-quality work light, go for it.


The underhood work lights can come handy at any time. You might need to use them in the middle of the highway or in a garage. That being said, you need to consider the weight of the light before making a purchase. The bulb needs to be portable enough to be carried around. However, portability doesn’t mean you should go for an extremely lightweight bulb that is made of poor quality components.

Lighting Modes

Now, the good news is that the underhood work lights have three lighting modes. These are designed keeping in mind the varying requirements of mechanics and automotive specialists. As mentioned before, car owners may need to use the underhood work lights in different places. Depending on the light in the area, you can set low, medium, and high lighting mode.

Some lights feature SOS lights and other light modes, which are designed for emergency purposes. Some bulbs come with extra lighting modes. If you think you are going to need the underhood work light frequently, then we recommend the bulbs with extra lighting modes.

Bottom Line

If you are working in an automotive repair company, then the underhood work lights can be your long-term investment. It will make it easier for you to access any car part. You can choose the underhood work light depending on what you need the lights for and your preference. The budget is also an important factor to consider. Like other car accessories, these lights are available at a different price.

Even car owners need to have an underhood work light. You never know when you are going to need one. It is better to store them in your car so that they are handy when needed. Try to buy a handheld light so that you can adjust it according to your requirements.


  1. Which is the best mounting option for work lights?

    The answer depends on where you want to use these lights. If you want to illuminate the entire engine, then underhood work lights featuring extendible arms will be your ideal option. If you want the bulb to illuminate a specific car part, then work lights with hooks will work wonders. These bulbs can be hung almost anywhere.
    The last option is the lights with a magnetic base. They are recommended for those who need to attach the light to the side of the car or bumper for a clear view. So, which one works best for your car depends on your preference and the work environment.

  2. Can the brightness of the underhood work light be adjusted?

    Yes, some work lights feature an adjustable lighting mode. You can set the lighting mode to high in a poorly-lit area. Likewise, you can switch to low and medium modes. However, not all underhood work lights feature an adjustable lighting mode. It is best to read the manufacturer’s description or contact the vendor before making a purchase.

  3. Can underhood work lights be used for other applications?

    Underhood work lights are specifically designed for vehicles. They help illuminate the poorly-lit areas, allowing you to access your car parts. But, these lights can also be used for other applications. As long as you choose the cordless and portable underhood work light, you can carry it anywhere you want. If you are willing to use these lights for home applications and other purposes, then try to find a portable and pocket-sized light that is easy to carry around.

  4. Can underhood work lights strain your eyes?

    First things first, underhood work lights are not the standard bulbs. They are brighter than a usual bulb or flashlight. There is no denying that some bulbs can strain your eyes and can bring on sudden dizziness and fatigue. But, that only happens when you stare at the bulb for too long. Just make sure you don’t stare at the lights. You only need them to deliver adequate light underneath your car and other parts. If you are concerned about your eyes and overall safety, we recommend the underhood work lights with a low level of lumens.

  5. Can underhood work lights cause a fire?

    Overheating is the primary cause of a fire in bulbs and LEDs. Fortunately, an LED cannot catch fire because they do not overheat. They might be brighter than regular lights, but they produce light at a relatively lower temperature than typical bulbs. It might still be pretty hot to touch (we highly recommend you avoid touching or starting at the light). But, it is better than halogen and CFL bulbs.
