There are four curved glass Lucas units on the holden site. They have used the same image for all four. It would appear to be a left hand dip/right hand drive example. I guess they couldn't be bothered to photograph each one individually. As two are labelled LHD, and two are labelled RHD, you would expect that they dip in opposite directions so two of them are right hand dipping for use on the continent or anywhere else they choose to drive on the wrong side of the road. Whether they are referring to right/left hand drive or dip is anybody's guess, but my money's on drive.
