Head and Tail Lights
The head and tail lights of the 2001 E39 have received a new look, utilizing optical wave
guide technology. The wave guides are an innovation that are not only aesthetically
pleasing, but also enhance safety.
Head Lights
The front headlights have been completely redesigned, however they fit into the existing
body without any sheet metal changes. The high and low beam headlights are free-form
reflectors and no longer use the glass lenses. The turn signal has been given its own
circular lens next to the low beam.

The parking light and side marker use the optical wave guide technology. Clear rings
surround the high and low beam reflectors. The rings are illuminated by a light source
module similar to the ones used in the Visual Entry Aid system. Output voltage for the light
source module comes from the parking lamp final stage of the LCM III. There is one light
source module located at the back of the head light housing between the high and low
beam headlights. The side marker for US models also has an additional wave guide con-
ductor for illumination.
Third generation Xenon headlights manufactured by Hella are standard equipment on V-8
powered cars and available as an option on the 6 cylinder models. All xenon equipped
vehicles also use LWR automatic headlight adjustment to maintain the vertical adjustment
of the headlights at any vehicle load. (
