Hey Jonny;
You don't need a picture they should mount so that the water drainage hole in the lense is at the bottom so that if any water gets into them it will drain out.

*note*
I have noticed that some vendors are selling the bracket and light assembly for one side only so the bracket may have to be drilled and the light assembly bezel may have to be punched on the opposite side in order for the water drainage hole to be in the correct position.
You may or may not run into this problem depending on the vendor.
