Installation 1-5

Step 1: After disconnecting power to the two headlamps and after removing the bulb access covers of the low beam, high beam or both bulb access covers, drill a small hole in the removed cover. The HID-Xenon bulb wire is passed through this hole for your headlamp upgrade.

Step 2: Reinstall the access panel and close it. Secure the small ballast to a convenient location in the motorbay.

Step 3: Finally attach power to the headlamp in the normal manner and the upgrade is completed. Headlamp realignment is recommended but only required if you have removed the headlamp during the upgrade which sometimes can be avoided (model and side dependant).

Step 4: Make sure that the ballast is installed in a safety place ,and ues the pads and ties to fix it

step 5: ， please try it several times, before using the ARL-HID.

It takes about 30 minutes to complete the installation. No special tools are required. Normal hand tools only.
