thanks for the replies...yea, i got the car about 2 weeks ago..no owners manual included! anyway, i registered on lexus.com to get a manual sent to me. in addition, a lexus tech is coming to the house next week to program the key...i'll bring up the "problem" then. as far as if new bulbs were replaced? im pretty sure theyre both stock. i can actually see at night when im parked on the driveway that the driver's side headlight is positioned higher than the passenger side. thanks for your help!
