Can you change the number plate light?

Yes. In most places you can replace the number plate light bulb or the entire light assembly, and you can upgrade to LEDs, as long as the replacement complies with local regulations and the plate remains clearly illuminated in white. It’s typically a straightforward maintenance task, but regulations vary by country and testing standards matter for roadworthiness.

What you can change

Number plate lighting is a required safety feature, and most vehicles allow you to update or upgrade the lighting without specialist equipment. The common options are described below.

• Bulb replacement: Replacing the existing bulb with the same type (base and wattage) is usually inexpensive and quick.


• Full light assembly replacement: If the lens, housing, or seal is damaged, you can replace the entire unit to restore proper illumination.


• LED upgrade: Some owners opt for LED bulbs or modules to improve brightness and longevity, while keeping the same housing.

When choosing an option, consider fitment, weather sealing, and whether the change will affect vehicle electronics or warnings. While replacements are common, use parts that fit your model and are road-legal in your jurisdiction.

How to replace

Follow these general steps to swap a number plate light bulb or unit. If you’re unsure, consult your owner’s manual or a professional.

1. Park on a level surface, switch off the engine, and engage the parking brake.


2. Access the light housing from the inside of the trunk/luggage area or from behind the bumper, depending on your car’s design.


3. Remove the lens cover or the protective trim to reach the bulb or module. Some housings require screws or clips.


4. If replacing a bulb, remove the old bulb, insert the new one of the correct base type, and re-seat the connector.


5. If swapping the entire unit, disconnect the wiring harness, detach the old unit, and install the new one with the same mounting points. Reconnect the harness.


6. Test the light by turning on the parking lights and verifying the plate is evenly illuminated from a distance. If you installed LED components, check for any warning indicators.

A quick reminder: ensure the protective seal is reassembled to keep out water and road grime, and dispose of old bulbs properly.

LED upgrades and electrical considerations

Upgrading to LEDs can offer brighter, longer-lasting illumination, but it may require attention to vehicle electrics and legal standards. Some cars monitor bulb status and can trigger warnings if non-original parts are detected.

Before you proceed, consider the following:

• Choose the correct LED type and base that fits your housing and works with your vehicle’s electrical system.


• Check for CAN BUS compatibility or install a resistor/load equalizer if your car alerts to a “bulb out” condition.


• Ensure the LEDs emit a true white light and illuminate the plate evenly; avoid kits with tinted or colored lenses that could fail regulation.


• Verify that heat dissipation and moisture protection are adequate to prevent premature failure.

LED upgrades are popular, but ensure the parts are road-legal and certified for use in your country to avoid fines or MOT/inspection issues.

Regulatory considerations

Lighting rules for license plates vary by country, region, and testing authority. In general, the plate must be clearly legible at night and in daylight, and the light should be white and unobtrusive.

Key points to keep in mind before you replace:

• Color: White light only; red, blue, or tinted lighting is typically prohibited for number plate illumination.


• Brightness and alignment: The plate must be evenly lit with no bright hotspots or dark areas, and the light should not glare into other drivers’ eyes.


• Certification: Use parts that are approved or certified for road use in your jurisdiction (ECE/CE markings or equivalent where required).


• Compliance checks: Some regions require a vehicle inspection or MOT to verify that the plate remains legible and the lighting complies with standards.

Because rules change and differ by location, always confirm with your local vehicle authority, inspector, or service manual before performing an upgrade or replacement.

Tips and common pitfalls

To help ensure a smooth, legal replacement, consider these practical tips:

• Keep a spare bulb or module of the correct type in your tool kit for quick future maintenance.


• Avoid cheap non-OEM LED kits that may produce uneven lighting or short lifespans.


• After installation, verify the plate is clearly illuminated from the recommended distance in your jurisdiction’s guidelines (often around 20 meters).


• If you notice flickering, color inconsistency, or warning messages, revisit the installation or consult a professional.

Proper maintenance of the number plate light helps ensure safety and compliance, reducing the risk of fines or failed inspections.

Summary

You can change the number plate light by replacing the bulb or the entire housing, and you can upgrade to LED options with careful attention to compatibility and legality. Always verify color, brightness, and certification requirements for your locale, and consider professional help if you’re uncertain about wiring or compliance. Keeping the license plate lit clearly and in white light is essential for road safety and passing inspections.

Can I get pulled over for a license plate light out?

Most states categorize equipment violations as non-moving. One of the most common non-moving violations has to do with the light for your license plate. You may not think much of this light, but you can actually receive a ticket for it if it burns out.

How do you change your license plate lights?

To change a license plate light, locate the light housing above the license plate, use a screwdriver to release the screws or pry the cover, remove the old bulb by twisting the socket or pulling it straight out, insert a new bulb (handling it carefully to avoid touching the glass), and then reassemble the housing.
 
1. Prepare for the change

• Gather supplies: Get a replacement bulb that is compatible with your vehicle. You may also need a flathead or Phillips head screwdriver.
• Safety first: Park your car, engage the emergency brake, and turn the ignition to the accessory position. 

2. Access the bulb

• Locate the housing: Find the light fixture(s) directly above the license plate. 
• Remove the cover: 
  • Screws: Use a screwdriver to remove the screws holding the cover in place. 
  • Pry-off covers: If there are no screws, use a flathead screwdriver to gently pry the cover off, or push in a notch to release it. 
  • Twist-off housing: Some assemblies twist to the side to release. You may need to twist the housing counterclockwise to detach it from the vehicle.

3. Replace the bulb 

• Remove the old bulb: 
  • Pull the bulb straight out of its socket. 
  • If it's a twist-in socket, rotate it counterclockwise and then pull the bulb out. 
• Install the new bulb: 
  • Handle carefully: Do not touch the glass of the new bulb with your bare hands, as the oils can cause it to burn out faster. Use a glove or a cloth if possible. 
  • Insert firmly: Push the new bulb straight into the socket until it is securely in place. 
  • Twist into place: If the socket twists, rotate it clockwise until it locks or clicks into the housing.

4. Finish up

• Reassemble: Put the light cover or housing back on and secure any screws you removed. 
• Test the light: Turn on your headlights to ensure the new bulb is working properly. 

Is it legal to change the color of your license plate lights?

If the new lighting obstructs the plate number visibility, this can violate state regulations. Most states allow white license plate lights only. Using other colors or styles, especially red lights, blue lights, or flashing lights, is unlawful.

Is it easy to change number plate light?

To remove the bulbs, simply pull gently. Try not to pull too hard, and if they don't come out straight away, be patient. Now you should be able to insert the replacement bulbs. As with all bulbs, take care to handle them gently as the glass of the bulb is often quite thin and delicate, and therefore easily damaged.
