Driving without headlights is extremely dangerous. If you notice that your lights have gone out, act quickly.
In this article, we will introduce in detail what to do first and how to deal with it when you are in a state of "I can't turn on my headlights!".
Causes of no headlights
What causes a car's headlights to go out? First of all, let's know the cause.
running out of balls
If you are using halogen lights for your headlights, in most cases the lights will not turn on due to blown bulbs.
headlights are
" Low beam " that can illuminate a range of 10m to 40m ahead
" High beam " that can illuminate a range of 30m to 100m ahead
These two types are used.
The high beam, which can illuminate a wide area, is characterized by the fact that it wears out quickly, but the low beam, which is used more frequently, burns out faster.
The brightness of the low beam is specified by the number of K (Kelvin), and the higher the number of Kelvin, the higher the heat generation and the faster the consumption.
If only one of the headlights does not turn on, please determine that the bulb is out.
blown fuse
Fuses are attached to electric wires used in automobiles, and are used to prevent current from flowing when a current higher than the standard flows.
Once the fuse blows, it cannot be used again.
If both headlights do not light up, determine that the fuse has blown, and replace the light and fuse.
Poor contact of relays and switches
If both headlights do not turn on even though the fuse is normal, there may be a "relay" or "switch contact failure".
If you can identify the location where the poor contact is occurring, you may be able to restore the condition by yourself using a contact restorer, but there is a risk that other locations will also malfunction.
Do not try to fix it by yourself, but ask for repair at a dealer or repair shop as soon as possible.
failure of the light itself
If your headlights don't come on and you're having trouble switching to high beams, the lights themselves may be faulty.
Ask your dealer or repair shop to inspect and replace the light.
Steps to take if headlights go out
If you find that your headlights have gone out, let's take steps to deal with it.
1. Check if the manufacturer's warranty is valid
First, check to see if the manufacturer's warranty is valid. If it's within the warranty period, you may be able to get a replacement for free.
2. If possible, keep the type of light down
There are about 3 types of lights used for headlights, and there are differences in replacement costs.
- Halogen bulb: about 5000 yen
- HID light: about 20000 yen
- For LED lights: about 20,000 yen
will incur a replacement cost.
3. Replace the light
If the type of lamp used for the headlight is a halogen bulb or HID light, it is possible to replace the headlight yourself.
However, trying to deal with it on your own can make things worse.
The safest and most accurate way to get your lights replaced is at a garage or dealer. Even if it costs money, you can't change safety. Please give top priority to safety.
The cause of failure differs depending on the type of headlight
There are actually three types of headlights on a car.
If you understand the features of each light, you can take measures for each type of light even if you suddenly encounter an accident where the light does not work, so let's grasp it here.
Halogen lamp
Halogen lamps are one of the most popular lamps. This type of light bulb emits light from a filament, and is characterized by its pale luminous color .
Since halogen lamps consume a lot of power and have a relatively short life of about 3 years, it is reasonable to conclude that the lamp has reached the end of its life when it suddenly stops working .
HID light
It is one of the types of lights that have been used since the 1990s and emits an arc discharge. It is a characteristic light that takes some time to reach its maximum brightness.
Unlike halogen bulbs, there is no need to worry about bulb burnout, but HID bulbs generally have a lifespan of less than 5 years.
If you have HID lights, it's reasonable to assume that they've reached the end of their life when the lights suddenly stop working.
LED light
It is a light that has become mainstream in recent years. It is also a major feature that it can be obtained at a relatively inexpensive price range and that it lasts considerably longer than other lights because the estimated life span is 15 years.
The maximum amount of light is reached at the moment the power is turned on, and the brightness is considerably brighter than other lights, but if it breaks down, it cannot be dealt with on its own.
If the LED light is installed, if the light suddenly disappears, it should be determined that some kind of problem has occurred, and immediately contact a repair shop or dealer .
Replace your headlights as soon as they stop working!
Driving a car without headlights is extremely dangerous.
There are street lights when driving in the city, and it is relatively bright, so you might think that it is okay even if you don't turn on the lights. may reach.
If your headlights no longer work, replace them immediately.
How to replace the headlight
Let's review how to replace the headlights of the car again.
For LED lights
Replacing the lights yourself is very difficult. Please ask a professional such as a dealer or a repair shop.
For halogen bulbs and HID lights
First, open the hood, remove the connector on the back of the light, remove the rubber cover and spring attached to the bulb, and remove the bulb.
Replace with a new bulb and attach the removed one.
There's nothing you can't do on your own, but even if you try to fix it forcibly, it may cause more damage, so it's best to ask a professional even for halogen bulbs and HID lights.
