Flickering Light.

[ballargan]

Hi All would really appreciate a little advice on a problem I've just noticed. With my van on hook up when I turn on the water heater, the light is very faint and flickers a little. If I turn on the heating switch that light is bright and stable. Any ideas?

Thanks in advance Ballargan

If you mean the 230v switch don't worry about it.
It will be a neon 'bulb'
The waterproof light switch in my garage has done it for the last 20 years at least.

Best to tell us the heater(s) you have got and give a photo of the switches. That way people which one to comment on, as there are several makes and types available.
