Know about the Tool and Other Specifications for Installing LED headlight bulbs

There are multiple light housing models such as H7, H4, etc. and different vehicles take different headlight housing.

Selecting the LED headlight beam

There are two types of LED headlight bulbs i.e., single beam headlight and the other one is diode headlight beam. If you want a high beam and low beam LED headlight beam, then a diode LED bulb would be the right choice.

Selecting the headlight beam pattern is important as it is the deciding factor in choosing one of the best headlights. In case you want to read more about LED headlight beam patterns, read our previous article on the beam pattern of the headlight to know more.

Prepare for LED headlight bulb Installation

Before you start to install car LED headlight bulbs, you should first mark the light beam pattern of the LED headlight bulbs so that you can set the new ones at the same angle. It is recommended to park your vehicle at about 20 feet distance from the garage or at any parking space where the distance between the car and the point of reference for making the light beam pattern is 20 feet.

Open your headlights, get a market or tape and find the center of focus of the LED beam pattern of the headlight. Once you have marked the points of beam patterns, the next step is to start the uninstallation of the already (previously) installed light housing system.

Pro tip: Securing the ballasts and wiring is important as you might need them again. We suggest you take two-sided tapes for securing the wiring and ballasts.

Ballasts and Wiring

As we have mentioned before, here is to bring more attention to the internal wiring of ballasts and wiring. Talking about ballast, it has two ends. One end of the ballast is inserted into the original wiring harness whereas the second end of the ballast wiring will be attached with the installation of newly LED headlight bulbs for your car.

Ballasts are exposed to moisture and extreme weather aligns with vibration. Therefore, to keep them protected, you can place them at the back of the headlight housing. Please note that this will be the last point of installing LED headlight bulbs.

Removal of Old Headlight Bulbs

To uninstall, the old led headlight bulbs, pop out the hood of the car light housing. Make sure that you carry out this process gently as you do not want to damage the hood and headlights inside. At the back of the headlight, there is a wiring connector that is attached to it. You can easily remove it with a flat screwdriver.

Now turn the headlight bulb connector very carefully to unplug it. If there is a metal base on the headlight assembly, that is fastened by a tension wired then all you have to do is to press down on the end of the wire to unlock it. after you have done it, just slide down the headlight out of the car kit housing.

Pro tip: before you start to install car LED headlight bulbs, make sure that you are wearing gloves and do LED headlights to get no fingerprints on them.

Connect the driver

For installing new LED headlight bulbs for your car, connect the driver once you have reinstalled the old headlight bulbs.

In the driver, there will be two (2) ends. Connect one of the connectors of the diver to the bulb and the other end of the driver with the wiring of your car.

Once it has been done, make sure that the placement of both sides is correct and workable.

Secure the Driver of the LED Headlight bulb

For securing the driver from any mishap or damage, you will need to place the driver on a gloat location toward the inner fender.

The second step is to mark the mounting holes with a sharpie, drill the pilot hole, and finally secure them with metal screws. There is another alternative for this process is using self-tapping screws or two-sided tapes for better safety.

If you do not want to use the driller for your car, then two-sided tapes would be the right choice. However, we recommend cleaning the surface with alcohol first and letting it dry. Then apply the tape.

Prop tip” do not use the zip ties as they lose when they vibrate and can lead to damage to LED headlight bulbs.

Time to Test Your Newly Installed LED Headlight Bulbs

Now, that you have put all the screws, ballasts, wiring, and LED headlight bulbs in their place, it’s time to switch the car on.

Start the engine of the car and test the headlights to see if the brightness and lighting direction of LED headlight bulbs is fine.

To check the headlight beam pattern, make sure that your car is parked at the distance where it was when you installed the headlight bulbs. Check the marking point of your LED headlight beam pattern for the old headlights and see if the beam pattern of the new headlights is in the same direction and point.

Also, check the following points after connecting and installing the new LED headlight bulbs:

  • LED headlight beam pattern
  • Even light distribution
  • No glaring or dark spots
  • The angle of the headlight beam pattern

If you find anything unsettling, reconnect it to make sure it works fine for the next time.
