License plate lights burn out and need replacing just like any other bulb on your vehicle

Your license plate light is a small bulb mounted above or below your plate that illuminates when your headlights are on. It burns out over time, and when it does, you have a burned-out light that a police officer can cite you for during a traffic stop. Replacing it is a straightforward task you can do yourself in most vehicles, though the exact steps depend on your car's make and model.

The whole job typically takes 5 to 15 minutes and costs between $5 and $20 for the bulb itself. You do not need special tools for most vehicles — just the correct replacement bulb and sometimes a screwdriver or plastic trim tool. If you are not comfortable doing it yourself, any auto parts store or mechanic can do it for you, usually for $20 to $50 in labor.

Key Takeaways

  • A burned-out license plate light is a traffic violation in all 50 states and can result in a ticket during a stop.
  • You need to know your vehicle's year, make, and model to buy the correct bulb — the wrong size will not fit or work.
  • Most license plate lights are accessed by removing a lens cover or trim piece held by screws or clips, then twisting out the old bulb and inserting a new one.
  • If you do not want to replace it yourself, any auto parts store or quick-lube shop can do it for $20 to $50 in labor.

Finding the correct bulb for your vehicle

The first step is identifying which bulb your vehicle uses. License plate lights come in several standard sizes, most commonly 194, 168, 2825, or 501. Your owner's manual lists the correct bulb type, or you can take your vehicle to an auto parts store and an employee can look it up by your year, make, and model.

When you buy the bulb, you have two main options: standard incandescent bulbs (the cheapest, usually $3 to $8) or LED bulbs (more expensive at $10 to $20, but they last much longer and use less power). Both types work fine for license plate lights. Some people prefer LED because the bulb will outlast the vehicle, but incandescent bulbs are perfectly adequate and cost less upfront.

Accessing the license plate light assembly

The location and access method varies by vehicle. On most cars, the light assembly is mounted directly above the license plate on the trunk or hatch. On some trucks and SUVs, it may be mounted on the bumper or tailgate. Look at the back of your vehicle and you should see a small rectangular lens or cover near the plate.

To access the bulb, you typically need to remove this lens cover. Most are held in place by one or two Phillips-head screws, though some newer vehicles use plastic clips or tabs that you pry gently with a flathead screwdriver or plastic trim tool. Once the cover is off, you will see the bulb socket — a plastic or metal piece that holds the bulb. Consult your owner's manual for the exact location and removal method for your specific vehicle, as the process can differ significantly between manufacturers.

Removing the old bulb and installing the new one

Once you have access to the socket, removing the bulb is straightforward. Most license plate light bulbs are held in by a twist-and-release mechanism: push the bulb in slightly and turn it counterclockwise about a quarter turn, then pull it straight out. Some bulbs pull straight out without twisting. Do not force it — if it does not come out easily, you may be twisting the wrong direction or pulling at an angle.

Before you install the new bulb, check that your hands are clean and dry. Oils from your skin can damage some bulbs and shorten their life. Insert the new bulb straight into the socket and either push and turn clockwise (for twist-in bulbs) or push straight in (for push-fit bulbs) until you feel it seat firmly. Do not overtighten — just snug enough that it will not fall out if the vehicle bounces.

Reinstall the lens cover by reversing the removal process: align it with the mounting holes or clips and either screw it back in or snap it into place. Turn on your headlights to confirm the new bulb lights up. If it does not, turn off the headlights, remove the cover again, and check that the bulb is fully seated in the socket.

When to have a professional do the work

Some vehicles have license plate lights that are difficult to access without removing trim pieces, bumpers, or other components. If your vehicle requires removing the bumper or extensive disassembly to reach the light, or if you are uncomfortable working on your vehicle, take it to a mechanic or auto parts store instead.

Most national auto parts chains (AutoZone, O'Reilly, NAPA, Advance Auto Parts) offer free bulb installation if you purchase the bulb from them. Some locations will also install it for free even if you bring your own bulb, though policies vary by store and location. Call ahead to confirm. A quick-lube shop or independent mechanic will typically charge $20 to $50 in labor to replace the bulb, which is reasonable if you do not want to do it yourself.

Why this matters for traffic stops and vehicle inspections

A burned-out license plate light is a moving violation in all 50 states. An officer can pull you over for it, and you can receive a ticket. The fine varies by state, typically ranging from $20 to $100, though some states treat it as a minor infraction with no fine, just a warning. In states that conduct vehicle inspections, a burned-out license plate light will cause your vehicle to fail inspection.

The violation is straightforward to fix and inexpensive, so it is worth addressing as soon as you notice the light is out. If you get a ticket for a burned-out light, you can usually show proof that you have since replaced it (a receipt from an auto parts store or a photo of the working light) and ask the court to dismiss or reduce the ticket, though this depends on your state and local court policies.

Checking both sides if your vehicle has two lights

Some vehicles have license plate lights on both sides of the plate, while others have just one. If your vehicle has two lights, check both of them when you notice one is out. It is common for both to burn out around the same time since they are the same age and get the same use. Replacing both at once saves you from having to do the job again in a few weeks.

If you are unsure whether your vehicle has one or two lights, look at the back of your vehicle in daylight and count the lens covers above or below the plate. Then turn on your headlights at dusk or in a dark garage and confirm which ones light up. This takes 30 seconds and tells you exactly what you need to replace.

Frequently Asked Questions

Can I drive with a burned-out license plate light?

Technically you can, but you should not. It is a traffic violation and an officer can pull you over and issue a ticket. The fix is quick and cheap, so replace it as soon as you notice it is out.

What if I buy the wrong bulb size?

It will not fit into the socket, or it will fit but not make proper contact and will not light up. Take it back to the auto parts store with your receipt and exchange it for the correct size. This is why confirming your vehicle's year, make, and model before you buy is important.

Do I need to remove the license plate to access the light?

Usually not. Most license plate lights are accessible from behind without removing the plate itself. Check your owner's manual for your specific vehicle, but in most cases you only need to remove the lens cover or trim piece.

Will an LED bulb work in my vehicle's license plate light?

Yes, LED bulbs work in standard license plate light sockets. They cost more upfront but last much longer and use less power. Some older vehicles have wiring that does not work well with certain LED bulbs, so if the LED does not light up, switch back to an incandescent bulb.

What if the bulb keeps burning out after I replace it?

If a new bulb burns out within a few weeks, you may have a wiring problem or a socket that is not making good contact. Have a mechanic inspect the light assembly to check for loose connections or corrosion in the socket. This is not common, but it can happen on older vehicles.
