How to Use and Install LED License Plate Lights
If you’re looking to update the look of your vehicle or ensure it meets legal requirements for nighttime visibility, installing LED license plate lights is a straightforward, cost-effective upgrade. These small, powerful lights not only help illuminate your license plate but can also contribute to a crisp, modern appearance for your car, truck, or SUV.
This comprehensive guide breaks down how LED license plate lights work, how to choose and install them, their advantages, common challenges, best practices, and answers to popular questions.
Understanding LED License Plate Lights
What Are LED License Plate Lights?
LED license plate lights are compact lighting fixtures designed to illuminate your vehicle’s rear license plate. They use Light Emitting Diode (LED) technology, which is more energy-efficient, longer-lasting, and typically brighter than traditional halogen bulbs.
Why Upgrade to LED?
- Increased Visibility: LED lights deliver clear, white light, making license plates easy to read at night.
- Modern Look: The crisp illumination adds a clean, upgraded appearance to your vehicle’s rear.
- Energy Efficiency: LEDs use less power, reducing strain on your electrical system.
- Longer Lifespan: Quality LED bulbs can last tens of thousands of hours, outlasting standard bulbs by far.
Step-By-Step: Installing LED License Plate Lights
Replacing your standard bulbs with LED license plate lights is a simple project most DIYers can complete in under 30 minutes. Exact steps can vary by vehicle, but here’s a general process to guide you:
1. Gather Tools and Supplies
- Replacement LED license plate bulbs (check compatibility for your vehicle)
- Basic screwdriver (Phillips or flathead, depending on your car)
- Gloves (optional, to avoid skin oils on new bulbs)
- Clean cloth
2. Access the License Plate Light Housing
- Turn off your vehicle and ensure the lights are off.
- Locate the license plate light housing—usually directly above or beside your rear license plate.
- Using the appropriate screwdriver, carefully remove the cover or lens. Some housings snap out or twist off by hand.
- Set the screws or cover aside (some housings are accessible from inside the trunk or hatch).
3. Remove the Old Bulb
- Gently pull the old bulb from the socket. Most bulbs pull straight out or twist out with a quarter turn.
- If the bulb is stuck, wiggle it slowly; avoid excessive force.
4. Install the LED Bulb
- Insert the new LED bulb into the socket. Confirm it matches the size and shape of the original.
- Before reassembling, test the light by turning on your car’s lights. If the LED does not illuminate, remove and rotate it 180 degrees (LEDs are polarity sensitive).
- Once confirmed, reinstall the housing cover or lens.
5. Repeat and Final Check
- Repeat the process for the second light if your vehicle uses more than one.
- Ensure both lights are working and the license plate is clearly illuminated.
Key Benefits of LED License Plate Lights
- Brighter Illumination: Improves visibility for law enforcement and safety.
- Durability: Resistant to shock and temperature changes.
- Low Maintenance: Fewer replacements, less hassle.
- Customization: Available in different colors (where legal) and styles to match your vehicle’s look.
Common Issues and How to Solve Them
LED Not Lighting Up After Installation
- Polarity Issue: Remove and flip the bulb 180 degrees.
- Socket Corrosion: Clean contacts with electrical cleaner and a cloth.
- Wiring Problems: Check for loose connections; repair as needed.
Flickering or Dim LED Bulbs
- Incompatible Bulb: Use LEDs built for automotive use.
- Canbus Error: Some vehicles detect low power draw as a fault. Add a resistor or choose “Canbus-ready” LED bulbs.
Legal Considerations
- Always install white LEDs unless your local laws specify otherwise.
- Check with your state’s motor vehicle department for specific requirements.
Practical Tips and Best Practices
- Buy the Right Bulb Size: Check your owner’s manual or remove the old bulb to read the size (commonly labeled as T10, 194, 168, etc.).
- Quality Matters: Opt for reputable brands to avoid premature failure. Look for warranties and certifications.
- Installation Caution: Don’t touch bulb surfaces with bare hands; oils can shorten bulb life.
- Clean as You Go: Wipe down the housing and lens before reassembly for maximum brightness.
Cost Considerations and Shipping Advice
- Price Range: LED license plate lights typically range from $5 to $20 per pair for basic models. Premium or OEM-fit housings can cost $25-$50.
- Where to Buy: Auto parts stores and online retailers offer a wide selection. Buying from trusted outlets ensures quality and return policies.
- Shipping Tips:
- Check for free shipping promotions, especially if purchasing multiple bulbs or kits.
- Consider the total cost, including shipping and handling, to avoid surprises.
- For urgent needs, local chain auto parts stores often offer “buy online, pick up in store” options.
- Look for bulk packs or bundles for larger savings if replacing multiple bulbs.
Vehicle-Specific Advice
Many popular vehicle makes like Toyota, Ford, Chevrolet, Honda, and Subaru use similar-sized license plate bulbs, making replacements easy to source. However, some models—especially European or luxury brands—may require specialized “Canbus” or error-free LEDs. Always double-check fitment and compatibility using your vehicle’s year, make, and model as a guide.
Brand and Product Variations
When shopping, you’ll encounter several options:
- Standard replacement bulbs: Just swap out your old glass bulbs for LEDs of the same size.
- Built-in LED housings: Some manufacturers offer an entire housing with integrated LEDs, offering weatherproofing and uniform light.
- Color choices: Stick with white to remain street legal, unless customizing for off-road or show purposes.
Premium brands often offer sealed, plug-and-play units designed for specific vehicles, which may cost more but simplify installation and boost durability.
Care and Maintenance
LED license plate lights require minimal care, but to keep them working optimally:
- Check regularly: Inspect lights for brightness and function, especially before annual inspections or long trips.
- Keep clean: Dirt and grime can dim effectiveness—wipe the lens with a microfiber cloth during car washes.
- Address issues promptly: Flickering or failed bulbs can be a sign of bigger electrical issues.
Frequently Asked Questions (FAQs)
Are LED license plate lights legal?
Yes, in most areas, LED license plate lights are legal as long as they emit white light and meet brightness requirements. Avoid colored LEDs unless specifically allowed by your local law.
How long do LED license plate lights last?
Quality LED bulbs can last 20,000 to 50,000 hours—often many years of regular use—outperforming traditional bulbs by a wide margin.
Do I need any special tools to replace my license plate light bulbs?
Typically, you’ll only need a basic screwdriver and possibly gloves. Some vehicles may require access from inside the trunk or special tools depending on the housing design.
Why is my new LED license plate light not working?
LEDs are polarity-sensitive; if it does not light up, remove the bulb and rotate it 180 degrees in the socket. Also, check for fuses and wiring issues if the problem persists.
Can I install LED license plate lights myself or do I need a professional?
Most people can install these lights easily at home with minimal tools. However, if your vehicle has complex wiring, Canbus systems, or integrated housings, consulting a professional or your dealership is wise.
In Summary
Upgrading to LED license plate lights is a simple, rewarding project that boosts both safety and style. With benefits like brighter light, improved energy efficiency, and sleek design, LEDs are a smart choice for most vehicles. Whether you’re looking to refresh your ride or comply with local regulations, following a few easy steps ensures a hassle-free installation.
