These R/C servo extension cables have Futaba style 3-pin connectors with standard gauge servo wire. They can be used with Hitec/JR style cables if the plug's plastic tongue is trimmed off with a pocket knife.

 

They can be used in a wide variety of applications, including camera hookups. For example, cut them in two and you end up with some very nice pigtails for your custom projects.
