Installing LED headlights into your Volkswagen Passat is an excellent idea, as LED headlights provide brighter lights and last a lot longer than their halogen counterparts. Installing the LED headlight wire connector to your Passat is essentially the same as installing a traditional halogen headlight wire connector. The connection is made in the engine compartment and can be easily accessed. In fact, the wire installation is so simple that it should not take any more than five minutes to complete.
Tools Used: Tools, Socket wrench
