2006 S60R bi-Xenon headlight response

I don't know what country you live in, but in Canada, on my '04 XC70, the movement takes about 1 second. I had to get the dealership to manually adjust the low beams, so maybe they can tinker with the apparent delay, if it's greater than 1 second.

Here's a short synopsis on my experience with bi-xenon head lights:

There seems to be a motor that simply moves the reflector to achieve high beams. In Canada we have daytime running lights (essentially low beam) but on my XC70, if I keep the light switch in the leftmost "off" position, then only the round daytime running lights stay on, saving my bi-xenon bulbs. If I leave the switch in this position, the highs will not activate. Also, there is a sensor on the centre console, just below the radio, that automatically switches the daytime lights to low beam bi-xenon when it gets dark outside (something not covered in the owner's manual). I initially found that the bi-xenons where staying on all of the time. The dealership said that the "twilight sensor" was blocked. Not knowing where to look, neither did the dealership, we discovered that a map was covering the sensor.

Good luck.... Cam

Not much to cope with. Mine shifts from low to high reasonably quickly, although not as fast as traditional lighting systems.

Far more problematic is the dim road lighting while on high beam. The light pattern is so dispersed to the side that objects other than highly reflecftive street signs remain un-illuminated. The lack of long distance coverage borders on dangerous in poorly lit roads. Bi-xenon lights on USA volvos also have a very sharp cutoff resulting in a total lack of road visibility on hilly roads. It is truly a poor design.

When I compare the "reach" of high beams on my S80 to the bi xenon's on the V70 the difference is striking.
