Fog Light adjustment

Hi please assist i have a mazda 3 facelift with the full fog lights fitted, the problem is that they are focussed very badly and despite being able to get behind them i am unable to see how to focus them, the older fog lights had a focus screw behind the plastic bezel but as this does not have the bezeli do not know how to focus the light, perhaps you could point me in the right direction to get a full mechanics manual for the car that could assist, your assistance is greatly appreciated.
i have attached a picture of the front of the car so you can see what i mean by the full fog light.
