These rubber gaskets protect the headlights from water. Remove the rubber gasket by simply pulling it off. Proceed to the next step once you are finished.

Step 2: Pull the wiring harness connected to the headlight

Inside the rubber gasket is the wiring harness. Pull these wiring harnesses connected to the headlight. Next, look for the little clip on the housing and lift it off. Now, remove the old bulb out of the headlight. Make sure, though, that you don’t touch the bulb.

Step 3: Mount your LED headlights

Now, mount one of your LED headlights in the housing where the old bulb used to be in place. You need to twist the collar ring out of the LED headlight and place it in the housing to do this.

Secure the collar by pushing back the little metal clip. Gently position the LED headlight to the socket. Twist it clockwise so that it will lock into place. Don’t forget to connect the plug.

Make sure that you line up the tab part of the locking ring against the locking grooves of the housing. Press the LED bulb while turning it clockwise. The flat sides of the LED bulb must be in the 3 o’clock and 9 o’clock positions.

As much as possible, turn the LED bulb gently since its locking ring is thin. Exerting too much force can damage it.

LED lights are becoming more popular in the automotive industry. It is because they provide brighter lights than halogens. Aside from that, they use less energy and have a longer lifespan than other headlights. When using LED headlights, you will also notice less fuel consumption.

The bright light of LEDs helps to see the markings and warning signs while driving on the road. Also, LED light can give you a broader coverage at night, making you see more of your surroundings.

In contrast, halogen light’s range is limited, only making you see what is in front of your car.

However, replacing your LED headlights can be more expensive than halogen replacement. Before replacing your headlight with LEDs, you must also make sure that it is legal in your country.

Some countries prohibit using LEDs as headlights because they tend to cause accidents. The bright light makes it difficult for the drivers of the passing cars to see the path.

Also, LED strips help add unique designs to the exterior and interior of your car. If you always drive at night, LED lights are a must-have!
