I have heard faulty grounds blamed for this problem
I believe, also, that if there is sufficient difference in resistance between the two bulbs on either side of a set, this can happen. (they need to match).
I think this thing works like a Ground Fault Circuit Interrupter (GFCI)in a home circuit. If there is an imbalance of current returning from one side of a particular circuit the thing is activated. So, just for kicks, get a new set of bulbs. (Do all three and be a big shot.) Then check your grounds for poor connections that may cause higher resistance on one side.
