[edited to be slightly more international] There exist any number of air fresheners which plug into wall outlets, but none which fit into light bulb sockets.
This one would. Furthermore, it would either have a lamp socket in it (just as some plug in fresheners have outlets in them), or have a light built into it, so you wouldn't be deprived of your light due to the desire for fresh scent.-- goldbb, May 07 2009 //But light bulbs on the ceiling don't have edison screw fittings\\ In that particular part of the world where I live ofcourse it might be different for other parts of the world and I wouldn't want to come of all (insert name of country) centered// - they have normal BC fittings. ES fittings are for special purpose uses.\\-- zeno, May 08 2009 Over here, light bulbs on the ceiling have edison screw fittings, and the only light bulbs I've ever seen with anything resembling a BC fitting were in a car.
Sounds like the air freshener company may have to develop multiple product lines in order to work with different standardized lightings in various parts of the world.-- ye_river_xiv, May 08 2009 I bet the desire for fresh scent varies in intensity according to cultural background and geographic location.-- bungston, May 08 2009 random, halfbakery
