They are all handed. In the UK they dip to the left, on the continent they dip to the right. on the round headlamps of the type the OP had, the dip is built into the lens
OP, you may be able to buy an insert for the existing shell, they are just a round healamp held in with wire clips so in theory any round H4 insert of the correct diameter should fit. I think they might be 7" but check that.
Hella make 7" inserts. ____________________ “Rule one: Always stick around for one more drink. That's when things happen. That's when you find out everything you want to know.”

The beam pattern is cast into the glass if the lens. Turning it upside down, altering the bulb angle, keeping it at all costs or anything else you could think of isn't going to make a LH dip headlamp of this type dip to the right with an acceptable beam pattern.
You can tape over part of the lens which will probably get it through an MOT but it does nothing for light output.
The only proper way to make a traditional sealed beam headlamp dip to the opposite side is to fit a different headlamp unit.
So as before, you can buy a good quality H4 sealed beam insert for about £30. Cibie and Hella are good makes. Actually, the lucas ones are surprisingly acceptable too given their reputation. ____________________ “Rule one: Always stick around for one more drink. That's when things happen.

See the roughly triangular-shaped section in the lens at the 3 o' clock position on the european insert and the 9 o' clock position on the UK insert? That's the part of the lens that kicks the dip down to the side of the road. If you use a right hand drive one while driving on the left, it'll kick the "dip" right into the eyes of oncoming traffic. Just so people can see the issue we're dealing with.
If you cover that area with black tape (neatly, all the bit in that section) it should be ok. It would pass an MOT like that and you're really supposed to do it if you take your vehicle into a country that drives on the opposite side of the road.

Interesting.
So if you rotate the UK one 180 degrees (by removing the headlight unit from the mounts and fitting it upside down) you get this:

Which is close, but no cigar, as it now kicks to the right and up. |

I'm surprised so many people never knew this.
According to Wikipaedia:
1962 Manufacture of the MZ ES 125/ES 150 begins. This was the first motorcycle with an asymmetric low beam headlight pattern.
Not sure if that's true or not.  ____________________ CBT: 12/06/10, Theory: 22/09/10, Module 1: 09/11/10, Module 2: 19/01/11
