lights = drop in idle

Hey guys,

I have a 2001 nb and as the title says I turned on my lights just before and only put them to the parkers and my idle dropped and stumbled but soon picked up again. When I turned on my lights fully after that my idle dropped and stumbled again!

Any ideas appreciated!
