The most important aspect of driving safely at night is having clear vision. When driving at night, you always feel that the road ahead is dark and you can’t see clearly. Many problems arise because the factory headlights are not clear enough. Car headlights not only help you see the road clearly but also enable other vehicles to notice your situation. Once the headlights break down, driving becomes very dangerous. Now, CoolLamp uses the simplest method to teach you how to check, repair and maintain car headlights.
1. Why don’t the car headlights work?
Answer:
-
The headlights’ bulbs have reached their lifespan: The bulbs have been used for too long and have reached their expiration date, or they were purchased with inferior quality bulbs, which caused the headlights to burn out.
-
The fuse has blown: The current inside the car suddenly increased or there was a short circuit, causing the fuse to burn out.
-
Lighting circuit problem: It might be that the connector of the headlights is loose, rusty, or the internal wires have broken.
1.2. How to solve these problems?
Answer:
-
Replace the bulb: Remove the damaged bulb and replace it with an original factory model or an LED bulb.
-
Replacing the fuse: If you are confident enough, you can directly refer to the repair manual and purchase the parts yourself to replace it. The safest option is to go to a repair shop for the repair.
-
Check for wiring issues: Check if the wire terminals are loose. If no problem is found, please go to the repair shop for inspection.
2. What could be the problem if the headlights of the car are dim on one side and bright on the other?
Answer:
-
The bulb has exceeded its service life: Bulbs have a lifespan. Once they are used for a long time, their brightness will decrease and they will appear dim.
-
Problem with the position of the headlights: It might be that they were repaired before, and during the reinstallation process, the angle of the headlights was not aligned properly, resulting in the light not shining correctly in the front.
-
The lamp cover of the headlights is yellowish or covered with dust: The lamp cover of the headlights has been exposed to wind and rain for a long time, resulting in it turning yellow or becoming unclear and dusty over time.
2.1. How to solve these problems?
Answer:
-
Replace the bulb: If you think this bulb has been used for too long or the original one doesn’t shine bright enough, simply replace it with a new one or use a brighter LED bulb.
-
Adjust the position of the headlights: Refer to the original car manual, and use a screwdriver to tighten the headlights back to their original position.
-
Replace the new lampshade: If it’s just dusty, just clean it. If the lampshade has turned yellow due to prolonged use, simply purchase a new one and replace it.
3. The inside of the headlights always gets foggy and there’s moisture. What should I do?
Answer: The sealing strip is damaged or the lights themselves do not have adequate sealing.
3.1. How to solve it?
Answer: Replace the new sealing strip to maintain the seal. If it’s a problem with the headlights themselves, replace them with ones with better sealing performance.
4. The car has been fitted with new LED headlights. What should we do if the dashboard keeps showing the malfunction indicator light?
Answer: Since the replaced headlights have been upgraded, they are no longer fully compatible with the original factory specifications. A decoder is required. Nowadays, many headlights come equipped with a decoder. If the decoder is not provided with the purchased headlights, please ask the merchant for it. Do not purchase randomly online as different headlights may not be compatible with the decoder.
5. Can the headlights purchased online be installed by oneself? Is the installation process convenient?
Answer: As long as you purchase the installation kit for the model of your car, the installation process will be very convenient. The current headlights are all designed according to the original factory specifications, meaning they can be plugged in and used directly. All you need to do is open the engine compartment, unscrew the dust cover, remove the old one, plug in the new one, and you’ll be able to see. However, during the operation, you must wear gloves and just don’t pull the wire ends forcefully.
6. Now there are so many online sellers of headlights. If I want to purchase in large quantities or make a bulk purchase, how can I determine whether the manufacturer is reliable or not?
Answer: Don’t just listen to the merchants telling you how great their headlights are. You should check if they can offer you a genuine warranty, if they can provide these certifications, and if there won’t be any disputes during the after-sales service.
CoolLamp Headlight Manufacturer offers a one-year warranty, provides US DOT and EU E-mark certifications, and responds within 24 hours for after-sales support.
Summary
When purchasing car headlights, make sure to choose the ones that match your vehicle model. The specifications will not be compatible. Try not to be tempted by cheap prices and buy cheap headlights as there is no guarantee. After all, when driving at night, seeing the road clearly is more important than anything else. When buying headlights, please keep in mind: the heat dissipation must be good, the light pattern should not be dazzling, and the built-in decoding must not give errors.
