Easy installation in general goes like 1-2-3-done as described below. 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. On the wire is a supplied adjustable tight rubber waterproof grommet to be fitted into the hole. Next, the HID-Xenon D2S/R bulb is fitted into the headlamp's base and locked into position via the factory locking device. No cutting of wiring is required on the installation.
	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 remo ved the headlamp during the upgrade which sometimes can be avoided (model and side dependant). It takes about 1-2hours to complete the installation. No special tools are required. Normal handtools only.
