The first time I drove my 2006 LS 430 at night, I thought I did not have my headlights properly turned on.
I could not see well enough to drive over 30 mph.
When I called the dealer the technition mentioned that I was the third person that week to make the same complaint so I left it for diagnosis.
Result- "no problem, "everything checked out to specs."
When I pushed the saftey issue, I basically got a shrug and was told that the headlight system takes a while to get used to.
I got caught in a rainstorm on the interstate last night and had to slow down to 35 mph.
I could not see anything but other cars were passing by with no problem.
