987 Litronics

[mixster986]

Saw a 987 with litronics tonight. The low beam seems to be "chopped off" at the top...a very flat line between light and dark; and the whole beam seemed to be somewhat low. High beams seemed to project normally. Anyone with a 987 have any insight into low beam litronics?

Are you asking if this is peculiar to 987s only? Factory fit Xenons or Litronics do have a very distinct cut-off line - its every credit to the designers of the optical projectors. They are designed to give the projection of as much light as possible to the low beam 'pool' but not to let it escape elswhere - to prevent dazzle of oncoming motorists or yourself (with reflection of roadsigns).

To attain 'e' approval in Europe, all manufacturers that factory fit xenon discharge headlights have to have self leveling and a headlamp wash facility fitted, to keep that cut-off as clear as you mentioned.

I have lits on my '02S, and those do not have the abrupt "cut off" at the top. I was just curious if the new headlamp design of the 987 was the reason for the chopped off top.
