How do you change the headlights in a car? How to replace your car s headlights steps

Replacing headlight bulbs does not necessarily require the purchase of so-called original parts, as long as the bulbs meet the relevant annual inspection regulations, we can choose some products produced by large manufacturers that can improve the night lighting effect. The key is to confirm what kind of plug your car bulb is, for example, the Chevrolet Cruze we used this time is an H4 socket, then you must buy a bulb with the corresponding socket. After completing the replacement of the bulb, we also need to adjust the light height by ourselves to ensure that it meets the qualification standards of the annual inspection.

Installation: Before replacing the headlight bulb, in order to avoid being burned by the components in the engine compartment when replacing the bulb, we need to confirm that the vehicle has been turned off and that it is in the cool state, and open the hood. Gloves should be worn when changing, which can not only protect your hands, but also facilitate handling.

Step 1: Unplug the bulb's power socket. Step 2:

After unplugging the power connector, remove the waterproof cover on the back of the bulb. Step 3: Remove the bulb from the reflector.

Bulbs are generally held in place by wire circlips, and some models also have a plastic base. Step 4: Put the new bulb into the reflector, align it with the fixed position of the bulb, pinch the wire circlips on both sides and push it in, and fix the new bulb in the reflector.

Step 5: Re-close the waterproof cover, plug in the bulb power, and the replacement operation is complete.

The specific operation steps for replacing the headlights of the car are as follows.

1. Plug in the power supply of the bulb.

When unplugging the bulb power socket, the strength should be moderate to avoid loosening the socket wiring or damaging the bulb plug.

Second, after unplugging the power interface, remove the waterproof cover behind the bulb, the material of the waterproof cover of the lamp is mostly soft rubber, and there is no difference between the waterproof cover of soft plastic material and some models, just a little force, you can see the waterproof cover broken.

3. Take the bulb out of the reflector, when taking out the bulb, you need to pinch the wire circlip on both sides with your fingers, and then pull out the bulb after the bulb is released.

Fourth, put the new bulb into the reflector, align the fixed clamping position of the bulb, and there are a number of fixed clamping positions on the base of the bulb. When installing, follow the steps to remove the old bulb and reverse the operation: pinch the wire circlip and insert the bulb into the reflector, align the installation position and release the circlip to fix the bulb.

5. When covering the waterproof cover, make sure that the edge of the waterproof cover and the fixed position are completely fitted. Finally, connect the headlight power socket and the replacement of the lamp is complete.

OK. First, it is related to the model:

If it is a Japanese car such as Nissan, Toyota, Honda, etc., the installation of the lights is very simple, basically you can change the calendar by yourself, that is, remove the halogen bulb of the original car, and then replace the LED on it. It can be disassembled and installed.

1.Open the engine compartment cover, observe the layout of the car parts on the back of the headlights, if the space is insufficient, then go to a professional "4S" shop to replace. Determine the headlight model of your car, and pay attention to the headlight identification model under the outer glass of the headlight.

2.Unscrew the headlight cover, noting that there will be slight differences in the method of removing the headlight cover depending on the model.

3.Forcefully unplug the lamp holder with the power cord, and pay attention to holding the lamp with your hand to avoid damage when unplugging.

4.Loosen the lampholder circlip to remove the lamp and replace it with a new bulb. The process of assembly and recovery is in reverse order of disassembly, which will not be repeated here. Be careful to reinstall the dust cap when you screw it on to avoid rain and dust infestation on the headlights.

Let's talk about the key point first, I only change the light source, that is, the bulb, whether it is LED or xenon bulb, it will not be easy to use, because the fit has no lens, the light is very scattered, and it is the same as not turning on on a rainy day.

It is best to go to a professional car shop to modify, remove the entire headlight assembly, and install lenses and xenon lamps to effectively improve.

Change the color temperature of the lamp not to be high, within 5000k.

If you want to be high, the lumens will be brighter.

The headlights of the big car can be replaced, and the replacement requires the replacement of the requirements of the vehicle, the brightness requirements, or the police uncle will be fined if you don't go on the road.

Car headlights can be retrofitted, halogen bulbs can be replaced with xenon bulbs, LED headlights or bifocal lenses. Whether the car sells the headlight modification can pass the annual inspection, according to whether the lamp of the filial piety meets the requirements of the car inspection, the relevant laws and regulations stipulate that the high beam of the lamp can not be less than 1450 lumens of early picoming, and the low beam can not be less than 1050 lumens, if it does not meet the requirements it cannot pass the annual inspection.

There are four key ways to modify car headlights, namely1. Replace high-power halogen lamps; the second is to install headlight brighteners; 3. Replace xenon bulbs; Fourth, replace the hydrogliding headlight assembly.

Car headlights can be modified in the following ways:

1.Replace high-power halogen lamps;

Replace the original 55W halogen bulb with a 100W high-power halogen bulb and do not make any changes elsewhere. This is the easiest and most convenient way to retrofit.

2.installation of headlight brighteners;

If the headlight brightness enhancement line is installed in the headlights and battery of the car, the voltage loss of the line will be reduced. It is expected that the voltage of the headlamp will be basically the same as that of the battery, and the brightness will be obtained, which will meet the objective requirements of the original halogen lamp.

3.Replace xenon bulbs;

Lensless halogen lamp: directly replaced with the corresponding model of xenon lamp, but due to the use of the reflector bowl of the original halogen lamp, the lighting can not be used reasonably, the lighting effect is limited, and other travelers must have.

Halogen lamp or xenon lamp with lens: The effect will be quite clear after replacing the xenon lamp, because the original car already has a lens, and the spotlight will be better. How much the specific effect can be improved depends on the quality of the bulb used and the lens of the original car, which meets the requirements of objective conditions.

The budget is not large, and the requirements for automotive lighting are not very high.

4.Replace the headlamp assembly.

Simply replacing the bulb is not very effective and carries the necessary risks, so the whole retrofit scheme is feasible. Some manufacturers have produced assemblies for some popular models, including xenon headlight assemblies and LE D headlight assemblies, which can directly replace the original car assembly. There are a variety of decorative lights to choose from in the package, which is easy and cool to install, and the lighting effect is greatly improved.

However, the quality of accessories, bulbs, stabilizers, lenses, decorative lights, etc. in the assembly basically accounts for the majority, which is suitable for small partners who do not want to destroy the original car assembly, have a high budget, and are not picky about the effect.

The following are the steps to replace the headlights: 1. Unplug the power socket of the bulb. 2. Unplug the power connector and remove the waterproof cover behind the bulb.

3. Remove the bulb from the reflector. Bulbs are generally held in place by wire circlips, and some models also have a plastic base. 4. Put the new bulb into the reflector, align it with the fixed clamp position of the bulb, pinch the wire circlips on both sides, and push it in, so as to fix the new bulb in the reflector.

5. Re-close the waterproof cover, plug in the power supply of the bulb, and the replacement operation has been completed.
