1. You must remove two clips inside each front-side tire-well.
2. Unscrew and remove the 10mm screw inside the tire-well with a 10mm socket. Do this for each front-side tire-well. The location of the three screws can be seen below.
However, you do not need to remove the "Upper Mud-Guard" from the car for this installation. Only the Lower Mudguard needs to be removed. 3. There still is one more screw hidden behind the upper mud-guard in the tire-well. Fold the upper mud-guard back to reveal this 8mm screw that is in between the lining of your car s fender and bumper. *Turn the tire away from you, so that you can create an easier accessing and free up workable space.
4. Please note that this step can be accomplished without removing the upper mud guard. However, Photo B shows the upper mud guard removed in order to show a better view of removing the clip that is conjoining the bumper to the fender. After you have removed the screw from Step 4, you must pull the pins off of the metal clip first before attempting to remove it. There is one metal clip on each front-side tire-well. Photo B 5. Unplug/disconnect bulbs and adapters from front bumper side markers and fog lights on each side before removing the bumper. Photo below shows side marker bulb and fog light adapter already unplugged do this for both driver and passenger side.
Photo below shows the inward side of the bumper where the bulb and adapter will be disconnected from.
6. There will be a Gear/Bolt that you will need to loosen before attempting to remove the bumper. The Gear/Bolt is located behind the upper mud guard and below the fender & headlight. 7. Photo below shows the Gear/Bolt exposed with the bumper removed. However, this is just an example to show what you are looking for behind the upper mud guard. You must loosen this Gear/Bolt before attempting to remove the bumper.
8. Next, you will need to remove two clips underneath your car s bumper as shown below. Once you have done this, you should be able to remove your car s bumper. Slowly and carefully, from one fender-end of your bumper to the other, pull the bumper off of your car s frame. 9. Remove two 8mm screws on top of the Headlight by unscrewing them with an 8mm socket
10. With all the Headlight mounting screws removed from the photo above, you will be able to remove your Headlight from your car. When removing your Headlights, please be mindful of where the adapters are and unplug them as you pull your Headlights out of your car s frame (as shown in Photo I below).
11. Before plugging in the main adapter for your headlights (as shown in the photo below) please check to see if the pins on the "female" end of the adapter are upright and aligned. In the case they are not upright or aligned, please do not try to connect the adapter. Connecting the adapter in this instance will further damage the pins and will adversely affect the headlight's performance. After you have checked to see if the pins are straight, connect the adapter securely by hearing/feeling the clip on the male end of the adapter "click" when latching on to the headlight.
* Step 12 & 13 applies only for Xenon HID Headlights. These two steps only apply if you have bought the optional Xenon HID version. If you did not purchase the optional Xenon HID version then please skip to step 14. * 12. Once you have secured your newly purchased Headlights onto its mounting bracket, you must prep to secure your HID Ballast also (shown in the example to the right). You must locate the HID Ballast mounting bracket (as shown in the example below), which was originally found from your recently purchased Headlight box. After you have located the HID Ballast mounting bracket you must secure it by screwing in all the necessary screws on it. 13. After you secure by screwing in all the necessary screws on the HID Ballast mounting bracket, you must loop a Zip- Tie through the HID Ballast mounting bracket so that you may secure it to your car. The HID Ballast must be seated on a metal surface not plastic. This is because the HID Ballast will get hot whenever the Headlights are in use. The HID Ballast mounting bracket should be seated on the tire-well s inward metal frame. Once you have correctly seated the HID Ballast mounting bracket, you must Zip-Tie the HID Ballast mounting bracket to the nearest metal hinge (be careful not to zip-tie the mounting bracket to any wiring or hosing of the engine compartment). After you have completed securing your HID Ballast mounting bracket, you may cut any excess Zip-Tie that is protruding out of the engine compartment. Repeat Step 10 for both sets of HID Ballast mounting bracket on each side. =====================END of Xenon HID Part of Installation=====================
14. Once you have removed your Headlights, you may back-track Steps 10 to Step 1 for the reinstallation of your newly purchased Headlights. 15. Once you have properly secured your newly purchased Headlights & HID Ballast mounting bracket to your car, you may now test your Headlights. If you have set the Headlight dial to any other setting than Position 0 (between Auto & Parking lights), switch it to Position 0. Your headlights should be off. Next, switch it to Position 1, also known as Parking lights, to see if your day-time running lights should be visible (it is the light nearest to the car s grille). Lastly, switch the dial to Position 2 to see if your low beam light is functioning. 16. Enjoy your newly installed Headlights!
