How Do I Know if My License Plate Light Is Out?

These lamps are attached above the plate’s rear frame and illuminate it in a downward direction. Yet, since this is placed in the rear of the car you’re driving, it’s highly possible that you simply won’t know if the problem exists until a police officer pulls you over. Nowadays, many trucks, cars, and SUVs have several sensors, computers, and monitoring devices that relay the potential issues to the person driving a vehicle. This technology, unfortunately, doesn’t include license plate lamps. Still, there are ways to check them. To avoid road rage from other drivers or driving anxiety, be sure to inspect these lamps before jumping into your vehicle.

If the Light Is Flickering Off and On, You Need to Replace It

These lamps should activate when you activate the headlights, including the parking ones as well. Remember that they are solid lights that could be either on or off. In many cases, however, they can start flickering. Such a situation can commonly happen due to a loose cable or connection. Flickering lamps can be highly dangerous and distracting to other drivers on the road. Not to mention that you’ll be attracting the police officer’s attention and most likely get a ticket.

To avoid driving stress and a situation such as this one, you should walk around your car once every week. Do this before a night drive. Just turn on your headlights, walk around your vehicle, and make sure these rear lamps are solidly illuminated. If you see flickers, go to a local mechanic or keep reading this article and find out how to change license plate light yourself.

If Your Rear Bulb Seems Foggy

Another signal of a potential issue is when the illumination appears foggy. Such a situation is most likely caused by water or condensation trapped within the light’s lens cap. Water can be leaking from the vehicle’s trunk lid inside the light’s lens when it is cracked. This is causing foggy illumination. As with the flickering, fogginess can lead to distraction on the road, and thus, you should replace the lightbulb and the light lens. Also, make sure that condensation or water is removed before it causes a short circuit because it can damage other systems inside the vehicle. With all other routine maintenance costs, you’ll be good without that particular one.

If Lamps Are Not On When the Headlights Are Turned On

The most obvious indicator of something being wrong is when the lamp is not lit when the headlights are on. This indicates that there’s either a problem with a loose connection, relay switch, or that the lamp has simply burnt out and had to be replaced. As we mentioned earlier, you should remove it and go to an auto parts store to get the right one and replace it.

Replacement license plate light bulb.

Replace Both Lamps at the Same Time

You should remove both tag lamps at the same time. If one has burnt out, the same will happen with the other one soon, regardless of maintenance. Firstly, be sure to check what kind of a lamp is available for your model and look up if your local auto supply store has it. As we mentioned, it’s suggested to obtain LED instead of incandescent lightbulbs. They usually cost around $2 to $3.

The Screws on the Vehicle’s Light’s Covers Should Be Loosened

The lamps are located above the license plate, close to the latch which opens your vehicle’s trunk. Look for screws that are holding the covers to your car and use a turnscrew to spin them counterclockwise. When you loose the screws, you’ll see the lightbulbs underneath the covers. During this process, it’s important to remember that the covers could also have attached rubber gaskets. They must stay attached to covers. Otherwise, water could leak into the lightbulbs and cause it to short out.

If the Lights’ Bases Are Attached to the Bumper, Rotate It From Underneath

All lamps attached to the back bumper typically don’t have screws. That is why you will have to go underneath your car and search for the black wires that will lead to circular ports on the bumper back. Rotate wires bases counterclockwise in every one of the ports and pull them out to access the lightbulbs. Remember to prepare a flashlight and use it to find the wires.

Pull the Lightbulbs Straight Out

The next step is to pull the lightbulbs gently in order not to break them. Grab them straight out from the bases. If the lamps aren’t coming out, you should search for metal or plastic tabs that are holding them in place. For the lightbulbs to come loose, press down on the tabs. It is crucial to remove the lightbulbs while your car is not running. Otherwise, you could get shocked.

New Tag Lights Should Be Pushed Into the Slots

Wearing cotton gloves while handling the new tag lights is extremely important. That way, you won’t damage or smudge them. Align them, so the prongs on the bottom are lined up with the holes in the bases. After that, you should push the lightbulbs into every base until they are securely placed. Remember not to force the whole process, or else you’ll shatter them.

Turn Your Car On and Check if the Lamps Are Working

Before you start placing the covers back on and securing the bases, start your car and turn on the headlights, and then check if the tag lights are lit. That way, you’ll be sure if the repairs worked. If they turn on, be sure to turn off your car so that you can keep on working. If they are not lit up, there might be an issue with your car’s wiring. In such cases, find a mechanic.

Secure the Lamps by Reattaching the Covers

Place the covers back above the lightbulbs so that the screw holes are lined up. Turn the screwdriver clockwise and tighten the screws back towards the covers. Once you attach the covers, the repair is done. In case you had to get out the bases from the car’s bumper, slide the bases back and turn them clockwise in order to secure them. And now your question — How do you fix a license plate light? — has been answered.

Maintaining small details like bulbs helps ensure a smooth and legal driving experience wherever you go.

How Can I Tell If My License Plate Bulb Needs Replacing?

You can tell your license plate bulb needs replacing if it flickers, dims, or stops working entirely. Inspect it at night or in a dim garage to confirm the issue. Sometimes, a dirty or corroded socket can cause the light to malfunction. Cleaning the area before replacing the bulb often solves minor issues. It’s smart to check all your exterior lights before a move or long trip. Keeping your car’s lighting system in good shape prevents unnecessary stops or repair delays.

What Tools Do I Need to Change a License Plate Bulb?

To change a license plate bulb, you typically need a screwdriver, replacement bulb, and gloves. Most bulb housings are secured with small screws or plastic clips. Gloves protect your hands and keep oils off the new bulb, which helps it last longer. Check your owner’s manual to confirm the correct bulb type. Having the right tools on hand ensures a quick, clean job. This simple maintenance step is worth doing before any road trip or relocation to keep your vehicle inspection-ready.

How Do I Change the License Plate Bulb Step by Step?

To change your license plate bulb, first turn off your car and locate the light housing above or beside the plate. Remove the screws or clips holding the cover and carefully pull out the old bulb. Insert the new one without touching the glass surface, as oils from your fingers can reduce its lifespan. Test the light before reassembling the housing. Secure everything tightly to prevent moisture from entering. Following these steps ensures a bright, functional light whether you’re driving locally or moving cross-country.

Can I Replace a License Plate Bulb Myself or Should I Visit a Mechanic?

Replacing a license plate bulb is an easy DIY task for most drivers. The process typically takes just a few minutes and requires minimal tools. However, if the light housing is corroded, damaged, or hard to access, a mechanic can help. Doing it yourself saves time and money, especially when preparing for a move or state inspection. Checking all your vehicle lights before relocating helps avoid issues with registration or shipping. A quick replacement ensures safety and compliance on the road.

What Type of Bulb Should I Use for My License Plate Light?

The type of bulb you should use depends on your car’s make and model. Common options include halogen, LED, or incandescent bulbs. LED bulbs are longer-lasting, energy-efficient, and provide brighter illumination. Always check your owner’s manual or existing bulb markings to ensure compatibility. Using the wrong bulb type can lead to electrical or fitment issues. Upgrading to LEDs before a move or long trip is a smart way to enhance visibility and reduce maintenance needs.

What Are the Signs of a Bad License Plate Light Socket?

A bad license plate light socket may cause flickering, intermittent lighting, or complete failure even after changing the bulb. Corrosion, dirt, or moisture buildup are common culprits. Check for rust or bent contacts inside the socket. Cleaning it with electrical contact cleaner can sometimes restore function. If the socket is too damaged, replacement may be necessary. Addressing this issue before a move ensures your vehicle passes inspection and remains road-legal.

Can Weather Conditions Affect License Plate Bulbs?

Yes, extreme weather conditions can affect license plate bulbs over time. Moisture and temperature fluctuations can cause corrosion or burn out the bulb faster. Cars exposed to snow, rain, or coastal air may experience more frequent light failures. Sealing the housing and using quality bulbs can prevent these problems. Before moving to a new climate, it’s smart to inspect and replace your bulbs. Adapting to local weather conditions ensures consistent performance and safety.

Why Should I Check My License Plate Bulbs Before Moving to Another State?

Checking your license plate bulbs before moving to another state ensures your car meets inspection and registration requirements. Many states require fully functioning exterior lights for vehicle approval. Replacing the bulbs beforehand helps you avoid delays at DMV or inspection stations. It also keeps you from getting ticketed during the relocation drive. Clean, working lights improve visibility during long-distance travel. Preparing your vehicle’s lighting system is an easy way to stay compliant and safe while moving.

How Can I Prevent License Plate Bulbs From Burning Out Quickly?

To prevent your license plate bulbs from burning out quickly, use high-quality replacements and avoid touching the glass during installation. Check for moisture leaks or cracked housing that could expose the bulb to water. Regularly clean the light covers to prevent dirt buildup. LED bulbs are a durable option that lasts significantly longer than standard halogen ones. Before a move or car shipment, inspect the light assembly for any wear or corrosion. A few minutes of maintenance can extend the lifespan of your bulbs and keep your car shining bright.
