not sure about lhs. but generally now, the head light comes out from the back of the light itself by turning the piece that the light goes into... if it is not possible to figure it out, the next time you go into get the oil changed, generally the service tech can do it. the type of blub should be on the bulb itself but if it isn't go into a parts store and ask for the correct bulb. the adjustment is generally fixed in the newer autos, if there are holes or indentations around the housing in the front outside of the auto, there could be adjustment screws located there. do not screw any more than 1/2 a turn at a time. out on the bottom means up and in on the top means up. in on the left means it moves to the left and out on the right means the same thing. reverse the turns to go the other directions
