Pull the light out from the INSIDE corner. Then pull straight out.
It takes a little more than lossening that "vertical' adjustment bolt. It actually is a bolt that secures the light from behind and really does nothing to "adjust" the aim of the light.
Check those lights you got. There is no means to adjust them. Mine came with the left light hunting for ducks and the right one with a big ass thumb print on the lense. They are now off my truck and back in the box in the garage.
The bulbs that come with them are weak as my factory foglights gave more light. Look to upgrade soon if you keep them.
I gotta tell ya, the stock lights are twice as bright and give a better pattern when using upgraded bulbs.
But those HALO lights are pretty cool as dusk...
