What tool do I need to tighten fog lights?

Flippant answers are useless.

My '06 OEM foglights use a T-15 (torx) bit to access the bulb, a T-20 bit to tighten the fastener for one axis and another oddball bit with hole in it to fit around a post in the fastener for another axis and a 13 mm wrench for the nut that holds the light assembly to the bumper. Typically I have only had to use the T-15 bit and the 13mm wrench.
 
First time I ever ran into a torx security head. Was able to use a small straight slot screwdriver. I believe a torx 35 would been the right bit.

Thanks for the answeres. Even the one about wrench.
