First take out the globe - unscrew the single screw at the bottom of the light housing, and gently pry up the bottom edge of the chrome light-surround. If it's the globe type, good lights are easy. A sealed beam has the filaments 'exposed' in the center of the reflector, where a globe will be obvious if you have that type. To check this, have a look through the glass. For these reasons you might get some unusual answers from US folks. Rob responded with a description of Australian headlights: US lighting laws are different to those in Australia, and their 12-volt Beetles usually have sealed beams, where we usually kept the globe-and-reflector type as were fitted to the older 6v beetles (now updated to 12v of course). Also, he wanted to know when the headlights are focused properly. He wondered if he increased the wattage of the bulbs would this melt the wires. Someone in Australia wrote asking about how to increase his headlight power, as his headlights seemed very dim.

Taillights - Off with the Ignition Off.

I have a coloured wiring diagram, and I took some photos of the wiring mess before I pulled it out, but it's definitely the most daunting task of resurrecting my 1970 Bug.My mechanic friend can't get me the large rubber grommet where the wiring comes through into the luggage compartment - just not obtainable anywhere. I found out that this was apparently true on the earliest VWs (6-volt maybe?) but on later models the main loom comes through from the engine on the left side behind the rear seat side panel, down to the floor (where the regulator sits on Generator models) and forward along a groove in the left door sill at floor level, then up through the sill (two holes) and up on the inside of the left front footwell (behind the carpet) to a hole through into the front luggage area.It'll be fun that's for sure. I always understood that the wiring traveled up/over the door jamb - past the interior light.

For Americans who express wire sizes in gauges, see this.This article includes the following subtopics. WiringNote: You will find excellent wiring diagrams for all makes, years and models of VWs at.Also Note: Wire sizes on these and most other wiring diagrams are printed on the wire in mm 2.
