Underglow neon lights can add a touch of personality and style to your car. However, when they start to flicker, it can be frustrating and take away from the intended effect. Don’t worry, though. In many cases, fixing flickering neon lights under your car is a manageable DIY project. This comprehensive guide will walk you through the common causes and provide you with step-by-step instructions on how to troubleshoot and repair the issue.
Understanding Why Your Car Neon Lights are Flickering
Before diving into the repair process, it’s essential to understand what might be causing your car neon lights to flicker. Here are the most common culprits:
- Loose or corroded wiring: Over time, vibrations and exposure to the elements can loosen wire connections or lead to corrosion. This can disrupt the flow of electricity, causing flickering.
- Faulty ground connection: A poor ground connection can also cause flickering lights. The ground wire provides a path for the electricity to return to the battery, and if it’s not properly connected, the lights may not receive a consistent current.
- Failing inverter: Neon lights require an inverter to convert the car’s DC power to AC power. If the inverter is faulty, it can cause the lights to flicker or fail entirely.
- Damaged neon tubes: While less common, the neon tubes themselves can sometimes develop cracks or leaks, leading to flickering or dim lighting.
- Dying battery: Although rare, a dying battery struggling to provide sufficient power can also manifest as flickering lights.
Troubleshooting Steps: From Simple Checks to Advanced Fixes
Now that you have a better understanding of the potential causes, let’s move on to troubleshooting the issue.
1. Check the Fuse
Before diving into more complex repairs, start with the simplest solution: checking the fuse. Locate your car’s fuse box (refer to your owner’s manual if needed) and find the fuse associated with your neon lights. Inspect the fuse for any signs of damage or a blown filament. If the fuse is blown, replace it with a new one of the same amperage.
2. Inspect the Wiring
Carefully examine all the wiring connections for your neon lights, including the positive and negative wires connected to the battery and the wires leading to the lights themselves. Look for any loose connections, frayed wires, or signs of corrosion. If you find any loose connections, tighten them securely. For corroded wires, use a wire brush to clean the contacts. In case of frayed wires, it’s best to replace the damaged section with new wiring.
3. Verify the Ground Connection
A poor ground connection is a common culprit for flickering lights. Ensure that the ground wire for your neon lights is securely connected to a clean, unpainted metal surface on your car’s chassis. If you find any paint or rust on the grounding point, scrape it away to ensure good contact. Tighten the ground wire connection firmly.
4. Test the Inverter
The inverter is a vital component in your neon light system, converting DC power to AC power. If the inverter is faulty, it can cause the lights to flicker. To test the inverter, you can use a multimeter. Disconnect the inverter from the power source and connect the multimeter leads to the input and output terminals of the inverter. If the multimeter doesn’t show the expected voltage conversion, the inverter is likely faulty and needs replacement.
5. Examine the Neon Tubes
While less common, the neon tubes themselves can be the source of the problem. Carefully inspect the tubes for any cracks, breaks, or dark spots. If you find any damage, the neon tubes will need to be replaced. When handling neon tubes, wear gloves to prevent leaving fingerprints on the glass, which can affect their lifespan.
When to Seek Professional Help
If you’ve gone through all the troubleshooting steps and your neon lights are still flickering, it might be time to seek professional assistance. A qualified auto electrician will have the expertise and tools to diagnose and repair more complex electrical issues. Additionally, consider professional help if you’re uncomfortable working with electrical components or are unsure about any part of the repair process.
Conclusion
Flickering neon lights under your car can be a frustrating problem, but with a little patience and the right approach, you can often fix the issue yourself. Remember to prioritize safety by disconnecting the battery before working on any electrical components and following the instructions carefully. By systematically troubleshooting the problem and understanding the common causes, you can get your neon lights shining brightly again, enhancing your car’s visual appeal.
FAQ
Q: Can I use LED lights instead of neon lights for underglow?
A: Yes, LED lights are a popular alternative to neon lights for underglow. They are brighter, more energy-efficient, and have a longer lifespan compared to neon lights.
Q: What gauge wire should I use for my car neon lights?
A: The recommended wire gauge for car neon lights depends on the wattage of the lights and the length of the wire run. Consult the manufacturer’s instructions or seek advice from an auto electrician for the appropriate wire gauge.
Q: Are neon lights legal for use on public roads?
A: The legality of neon lights on vehicles varies depending on your location and local regulations. Check your local laws and regulations regarding the use of underglow lights before installing them on your car.
Q: Can I install neon lights myself, or do I need professional installation?
A: While installing neon lights is achievable for DIY enthusiasts, it involves working with electrical components. If you’re unsure about any part of the installation process, it’s always recommended to seek professional installation to ensure safety and proper functionality.
Q: How do I choose the right inverter for my neon lights?
A: The inverter you choose should match the wattage of your neon lights. Ensure the inverter has enough capacity to power your lights without overheating.
