Precautions and Preparations

Whenever installing any automotive accessory installation you always want to be sure to have the correct protective gear and equipment. Please wear goggles or other eye protection while installing any aftermarket parts. It is also advisable to wear heavy duty work gloves where appropriate.

It is also recommended to spread out a tarp or mat on the floor adjacent to the vehicle to use as a staging area for your removal and installation. This is to prevent damage or scuffing to the delicate finish of the OEM or replacement aftermarket headlights.
