Rotation problem

[MrMan]

I'm trying to set up a rotating light, but i can't get it right. Basically i have a block, with a light attached to either side...i've tied the block to a func_rotating and the lights are parented to that entity...it works, just not how i want. Instead of rotating on the spot (i.e. turning round)..it goes for a little trip in a circle (see attached image)...how can i fix it to rotate/turn on the spot?

have you moved the origin/pivot points to the right place for it to rotate correctly?
