In Reply to: Xenon Upgrade posted by Denik on January 07, 1999 at 19:55:02:

: I noticed that Xenon only cost $500 more on the '99 5 series. I have a '98 5-series and have been considering an upgrade to Xenon. Does anyone know if the dealer does it? I went to D2Technik and they quoted me a price of $1500 for the upgrade!

For your info.

The following was taken from the Hella site (

Hella makes the current lights for BMW, and this design will be close to the BMW OEM product - but as I understand it, BMW have their own specifications regarding the operating software - especially the auto aiming system.

This does give some indication of how long they expect an installation to take - probably assumes the person has done it before.

I have no further details - you will have to contact Hella.

Xenon headlamps now available for retro-fitting

Hella can supply retro-fitting package for BMW 5-series and Mercedes-Benz E-series

Hella can now supply headlamps with xenon light for retro-fitting to the current BMW 5-series and
the Mercedes-Benz E-series models. In addition to the headlamps themselves, the package also
includes an automatic headlamp-range adjustment system and, if it is not already fitted to the
car, a headlamp cleaning system. These components are mandatory under ECE Regulation R98 of April
1996 for xenon headlamp systems.

The automatic headlamp-range adjustment system ensures that the xenon headlamps are always aligned correctly, regardless of the load the car is carrying. An axle sensor developed by Hella with an integral control unit is mounted on the rear axle, from where it can measure the degree to which the vehicle is being pressed down on its suspension. Changes are communicated to an actuator attached to the headlamps which makes sure that the xenon light is always aligned correctly and does not dazzle.

When the driver operates the windscreen-washing system when the headlamps are switched on, they
are also cleaned at the same time. The headlamp cleaning system works on the water-jet principle;
a rotary pump generates the necessary water pressure, and the kinetic effect of the drops of
water, directed through special swirl-chamber nozzles, forces the particles of dirt off the
headlamp and rinses them away. Clean headlamps are best for lighting up the road and prevent the
dazzle that might be caused by stray light reflected from the particles of dirt. It is estimated that installing the whole package will require about 5 man-hours, or 3 man-hours without the headlamp cleaning system.
