I pulled up next to an Acura TSX today at a stoplight, and was comparing the headlights between our cars. The Acura's xenon's had a flat beam pattern (just a flat top line), but my car's xenon's had a V shaped pattern (horizontal on the left, but with an upwards incline of about 30 degrees on the right side, on both headlamps). I wanted to check if that was a problem with my lights, or if it was the beam pattern that Volvo chose to use on our cars.

So chime in. If you have xenon's on your S80, does your car have a beam pattern like #1, or #2

Yours is probably more like #2 since you cranked them so high up...
Wait, yours looks like #1?

And doesn't the tilting turn the entire headlamp housing upwards? So the beam pattern shouldn't change with height adjustment. At least that's what I think.
Am I wrong?

Vivek, the beam pattern rising up on the right side is most definitely intentional, and is there to illuminate road signs and other objects on the side of the road. I first encountered this lighting pattern when I installed Cibie 7" round headlights to replace the tungsten headlamps on my car back in 1980, so that beam pattern idea has been in use for at least 30 years, and probably longer. And don't call be a geezer! Not yet anyway!

Oh, and to answer your question, yes I have the same beam pattern on my S80 and LS430 as you do.

Re: Xenon Beam Pattern (MAC1LSR)

By the way, I should mention that I have raised the beam pattern on my S80 by turning the 6mm adjustment screws 2 1/2 turns counterclockwise. Like many cars with Xenons, they are adjusted from the factory to point down too much, so that the distance they illuminate is very short. I've had to do the same on my LS430. The drawback of doing this is much poorer performance in foggy conditions. And it probably is more bothersome to oncoming drivers, although I have never had anyone flash their highbeams to me while driving my S80, LS430, or V70R (on which I've also raised the beams). You have to be careful not to raise them too high, or headlight performance drops.

2.5 turns. That's what mine needed too.

Lol. I have no idea how many turns I did. Probably 3 ish or more. The world may never know.


But I feel better knowing that my lights aren't messed up. It just was a bit awkward when I saw that the Acura's had a completely 100% flat beam.

And MAC - thanks for the responses! Very helpful. You mentioned you had an LS430. I thought I remember seeing one of those too, and if I recall, it also had a flat beam. But you would know better since you have the car itself.


Side note - I saw a LS460HL today, and boy, that car looked nice. Probably just because it was so expensive! http://********************/smile/emthup.gif
