How do you replace the license plate light?
Replace the license plate light by removing the lens or cover, swapping in a new bulb of the correct type, and testing the light.
In most cars, the license plate light sits above the plate or in the rear bumper area. The bulb type varies by manufacturer, so always verify the right replacement before you begin. The steps are generally similar across models, but some vehicles use LED modules that may require a whole new housing.
What you’ll need
Before you start, gather these tools and parts to ensure a smooth replacement.
- Replacement bulb of the correct type (common options include W5W/194 or 168 for incandescent bulbs; some cars use dedicated LED modules or sealed units).
- Flat-head and/or Phillips screwdriver (if screws hold the lens or housing).
- Trim tool or a plastic card to gently pry the lens without damage.
- Gloves or a lint-free cloth to handle bulbs (prevents oils from your skin from shortening bulb life).
- Clean rag and contact cleaner (optional, for corrosion).
- Owner’s manual or a quick model-specific reference (to confirm bulb type and access method).
With the tools assembled, you’re ready to access the lamp housing and replace the bulb securely.
Bulb types and compatibility
License plate lights use a few common bulb types, and some cars use LED assemblies. Check your vehicle’s manual or inspect the current bulb or housing to confirm the correct part.
- Incandescent wedge bulbs such as W5W/194 or 168 (these are common in many older or mid-range models).
- LED license plate modules (integrated LEDs; often you replace the entire assembly rather than a single bulb).
- CAN-bus or model-specific bulbs (some vehicles require a particular type to avoid warning lights).
Using the correct bulb avoids poor brightness or fit issues and prevents electrical problems.
Steps to replace the license plate light
Follow these steps in order to replace the bulb safely and correctly.
- Turn off the ignition and lights. Optional: disconnect the negative battery terminal to prevent shorts.
- Gain access to the light housing by removing the license plate or popping off the lens cover, depending on your model.
- Carefully remove the old bulb from its socket. For twist-in bulbs, rotate counterclockwise; for plug-in styles, gently pull straight out.
- Identify the replacement bulb type and install the new bulb, avoiding contact with the glass with bare fingers (wear gloves or use a cloth).
- Reconnect the socket and reseat the lens or plate. Reattach any screws or clips securely.
- Test the light by turning on the headlights or manually activating the license plate light to confirm it works.
After completing the steps, ensure the lens is seated properly and the plate remains secure against the bumper or trunk edge.
Testing and maintenance tips
After installation, test the light in darkness to verify brightness and coverage. If the light does not illuminate, recheck bulb orientation, fuse, and wiring connections, as well as the seal around the housing. For LED assemblies, if the light fails, you may need to replace the entire unit or the LED board, which can require professional service.
Summary
Replacing a license plate light follows a simple sequence: access the lamp, remove the old bulb, install a new one of the correct type, reassemble, and test. Always verify bulb type for your vehicle, handle bulbs with care, and consult a professional if LED assemblies or electrical issues arise.
