Quick Answer
Replacing the license plate lights on a 2018 Toyota RAV4 requires a non-marring trim tool and 168 (or 194/T10) bulbs. You simply pry the lens housing from the exterior, twist the socket counterclockwise to remove the old bulb, and insert the new one. Always test the lights before snapping the housing back into place.
Replacing the license plate lights on your Toyota RAV4 is a quick DIY job. You need a non-marring tool, type 168 bulbs, and a pair of gloves. You will pry the exterior lens, swap the bulb, and snap it back. Below you find the full walkthrough, tips on avoiding mistakes, and advice for keeping your lights working long-term.
Key Takeaways
- Pry the lens housing carefully from the exterior liftgate trim using a non-marring tool.
- The correct replacement bulb is a 168 (often sold as 194 or T10).
- Wear gloves when handling new bulbs to prevent skin oils from causing premature failure.
- Test the lights before you snap the housing back into the vehicle body.
- Dispose of old bulbs according to local recycling regulations.
Why License Plate Lights Matter
License plate lights keep your plate readable for other drivers and law enforcement at night. Most states require functioning plate lights by law. Driving without them often leads to a traffic ticket or a fix-it citation.
Your 2018 Toyota RAV4 uses two type 168 bulbs for this purpose. Replacing a burnt bulb immediately keeps you road-legal and maintains the look of your vehicle.
Essential Tools for the Job
You only need a few items for this task. Gather these before you start to make the process efficient.
- Non-marring tool: Use this to pry the lens cover without scratching the paint.
- 168 bulbs: These are standard and interchangeable with 194 or T10 sizes.
- Gloves: These keep skin oils off the glass surface.
Keep your workspace clean to avoid losing small parts. Oils from your skin create hot spots on the glass and significantly shorten the bulb lifespan.

Step-by-Step Instructions
Ensure the vehicle is off and the lights are switched off before you begin. For extra safety, you may disconnect the negative battery terminal, though it is not required.
Find the license plate light lens on the underside of your liftgate. Insert your non-marring tool into the edge of the lens and gently pry it outward.
Once the housing pops out, twist the bulb socket a quarter turn counterclockwise. Pull the socket out to reach the old bulb.
Remove the old bulb by pulling it straight out of the socket. Insert the new 168 bulb firmly.
Put the socket back into the housing and twist it clockwise to lock it. Snap the entire assembly back into the liftgate. Always test the light before you finish the job.
Proper Bulb Handling and Disposal
Wear gloves when you pull out the old bulb. This protects your fingers from sharp edges on the housing.
Dispose of used bulbs responsibly. Old bulbs contain materials that can be hazardous. Check if your area has recycling programs through your local waste management service. Many auto parts stores also accept used bulbs for recycling.
Always consult a qualified professional if you feel unsure about your vehicle’s electrical components.
Choosing the Correct 168 Bulb
Picking the right bulb is vital for visibility. These bulbs are typically rated at 5 watts and provide enough light to keep your plate visible from 50 feet away.
Always check your owner’s manual to confirm the specific bulb size for your model year. The 168 is a standard fitment that is interchangeable with 194 or T10 types. Quality bulbs from reputable brands generally last longer and perform better under vibration.

Installing the New Bulb
Ensure you have the correct 168 bulb before starting. Insert the new bulb into the socket until it clicks. If it feels loose, the bulb could rattle free while you drive.
Slide the socket back into the housing. Turn it a quarter turn to the right to lock it. Give the lens a gentle push to ensure it sits flush with the liftgate trim.
If the light fails to turn on, remove the bulb and verify that the contact points are clean. Sometimes, the bulb simply needs a slight adjustment to sit properly in the socket.
Common Mistakes to Avoid
Avoid these errors to keep your installation smooth:
- Using a metal screwdriver will likely scratch or crack your plastic lens covers.
- Skipping the test step means you might have to pry the housing out twice.
- Handling new bulbs with bare skin leaves oils that cause early burnouts.
Always lock the housing securely. A loose housing allows moisture to enter, which causes corrosion over time. Do not over-tighten, as the plastic tabs can break easily.
Testing the New Lights
Turn on your vehicle lights. Walk to the back of the car to verify both bulbs glow steadily.
If a bulb does not light, check the fuse box. A blown fuse for the license plate light circuit often causes both bulbs to fail at once. Use a multimeter to test for voltage at the socket if you cannot find a blown fuse.
LED vs. Incandescent Bulbs
You can choose between stock incandescent bulbs and LED upgrades. Incandescent bulbs are cheap but have a shorter lifespan.
LED replacements in the 168/194/T10 size cost more but last for thousands of hours. They also produce a crisp, white light that modernizes the look of your RAV4. Ensure your LED bulb is “CAN bus ready” if you want to avoid dashboard warning lights or flickering.
Long-Term Maintenance Tips
License plate lights are easy to ignore until they fail. Check them every few months for dimming or flickering.
Clean the lens covers during your routine car wash to remove road grime. Keeping the lens clean ensures the light stays bright and visible. Keep a spare pair of 168 bulbs in your glove box for emergencies.
