Headlight bulb/fog problem

[nik patel]

Hope someone can help

I have a seperate bulbs for main lights and fogs(located in headlight).

When the main lights are on and i flash or put the fogs on, the nsr headlight turns off and the fog comes on but only a third of its full power. I have check the bulbs and connections and they are fine.

Any ideas?
