Like most modern combined headlight units they're not adjustable separately.
The headlight reflectors are probably buggered, the metalising was done on the cheap, they left out a vital process which protects from overheating. This problem is made worse by the fitment of higher wattage bulbs! Mind you the MGF lights aren't all that great at the best of times.
However there are solutions, you can get the reflectors remetalised, you will need to remove the reflectors (very bloddy carefully, like all modern plastic rubbish they are easily broken) and take/send them to the metalisers. Once done I recommend fitting Osram Night Breaker
( Laser next generation)
55watt bulbs, these are probably the best bulbs on the market ATM.
Or fit some driving lights.
I don't know anyone in QLD that does metalising. I used
