Jim Coleman light problem

So my circular fluorescent light on my Jim Coleman vacuum was burnt out and the ballast was broken. So what should I do? Well, what about installing 2 compact fluorescent lights? I thought it was a good idea.  My only problem after I installed the lights was that the lights staying on all the time and when the vacuum is turned on the lights go off, any ideas?
