Legal height for focus of head lights

Question

What is the legal height that your cars head lights should be focused at, and over what distance is this? As on both my cars, headlights one points up and the other points way down. This is not only dangerous for me and my family but to on coming traffic. When my vehicles go for services I have requested the mechanics to do this for me, to no avail. I have tried to google this information with no success. Please help.

Answer

Your dips may not "strike the road" more than 45m ahead of the car. Your brights must strike the road a minimum of 100m ahead. If your mechanic can't help you, perhaps ask a local roadworthiness testing station - they have equipment to test whether headlights are in spec or not and they might be able to advise on adjustment.
