While you can adjust them up/down + left/right this will NEVER fix the problem you have which is the RHD beam pattern. If you adjust them as much as you can to not blind oncoming traffic the light output on the road for your use is next to nothing.
You'll have to acquire a LHD beam pattern insert off ebay (or somewhere else but I found mine there) and take apart the headlights to install it.
It's a time consuming process but not hard if you have all the tools. I used a heat gun instead of baking them because I didn't want to risk ruining my expensive headlights.
Once the piece is installed into the projector housing you reverse the process and then plug them up with a lightwerkz wiring unit and you're done.
You'll be much happier with the light output and all other drivers on the road will thank you for not blinding them.
