A few weeks ago, I repalced the stock headlights with KC HiLite LED lheadlights (you can search for it). Below, I describe what I saw when I held the assembly in my hands.
I did not change how the headlights point. First, I pointed the lights at the back wall in my garage to compare the height of KC HiLite's beam vs stock. Then I went for a drive. Even with the very bright KC HiLite LED headlights, oncoming traffic did not flash their lights at me.
THE ASSEMBLY
The headlights are mounted to a an assembly that looks very similar to the attached picture (it is not a Roxor headlight mount).
The two rings are held apart by two springs and an adjustment screw. You can see the springs in the attached picture.
The inner ring has the bolts to mount the assembly to the Roxor.
The headlights are mounted to the outer ring.
Standing in front of your Roxor, looking at the headlights, one spring is at the 3 o'clock, one at the 9 o'clock (under the headlight bezel). The nuts for these adjustment screws are on the inside of the grill under rubber caps. (DAMcar's picture at the start of this thread shows a nut without the rubber cap).
The adjustment bolt is at 12 o'clock. Inside the grill, on top of the headlight is a plastic assembly. This is where the adjustment bolt is located (Bister's & General's post)
UP - DOWN ADJUSTMENT
As the adjustment screw turns, the outer ring pivots on the springs towards or away from the base.
LEFT - RIGHT ADJUSTMENT
Looking at the assembly, I think you may have to remove the bezel.
Before you pull off the bezel, remove the rubber caps and turn the screws at 9 o'clock or 3 o'clock. This may work.
Turning the nuts may turn the screw, too.
If so, you would need to remove the bezel and access the heads of the screws from the front. (Takes less than 10 minutes)
There is a nice YouTube video that shows how to remove the headlight assembly.
