The light is there solely for the purpose of allowing other parties the knowledge that they are being filmed. It is the same on all recording devices (UK anyway) be it your mobile phone or camcorder. Why do you want it disabled unless you like to sneakily film people? I haven't got a problem with the light being on as I'm not hiding in a bush or filming people who dont want to be filmed or not know that they are being filmed. If you need to disable this light then you have to question what exactly is it that you are filming.
