I do not have South African lamps.  I bought a rectangular headlamp that replaced the rectangular one I removed.  Neither one had an opening through which a bulb could be installed.  They look like sealed beam headlamps to me.  Others say that is not correct, but I sure did what I did.  It is out there in my garage right now.  I am not going to remove the grill to look right now.  But there it is.

My other vehicles use halogen bulbs inserted into the headlamp assembly, so I know how that works.  mcneely
