Im trying to find the following items, but RadioShack nor homedepot has any of them. Does anyone know where I can find these products?

An in-line outlet that pulses electrical output. In other words, I need a plug that will plug into an outlet and I can plug one of my lights into it. The plug will then automatically turn on and off the electricity continuously so that my light will continually turn off then on, off then on,... I already own one of these but I don't know where to get more/ different frequencies.

A non-shatterable regular light bulbs with a very very dim light. Only a few
Watts. Nice flickering bulbs would also work if they looked realistic (not those stupid flame flickering ones).

Does anyone sell other electrical lighting options for professional haunted houses?

Thanks
Nathan
