2 way switch with indicator?

[Harnser]

I have 2 light switches for my garage lights: one inside the garage by the door, the other in the kitchen. This lights are regularly, accidentally, left on for hours, because people forget to turn it off in the kitchen, and when the fire door is shut you can't see any light.

I want to add a visual reminder that the light's on, but cannot find a 2-way switch with a built-in indicator. I bought one of the glow panels to fit behind the lightswitch, but the instructions warn that it must light up only when the light is off (the opposite of what I need). I also bought one of the 20A appliance switches but can't figure out a way to convert it to be 2-way.

Is this impossible to do with 2-way wiring?

Do you have a neutral at the switch you want the indictor at, if not then you are a stuck. Its not the type of indictor thats the problem, its having the neutral there, if you had a neutral, then you could use the switch locactor surround you bought.

I got the switch off today, this is what's behind:

The blue's the neutral right?

No neutral there, if you want a neon indicator you are looking at trying to replace the twin and earth from the fitting to the switch with 3c and earth.

Okay thanks. I've got to take the garage ceiling down sometime to insulate the floor of the bathroom above so will save this task for then.

Interesting it looks like this has already been replaced once in the past (why?) due to the switch drop being in harmonsided colours (brown and blue) and the 3c+e for the strappers being in old colours (red, yellow, blue). Unless the job was done around 2004 with an old stock of 3c and E (by someone who did not belive in sleeving lives, either....)

The room the switch is in was built 15-16 years ago, so that fits with the old stock. Much of the building work was done by the previous owner, and who knows who he got in to do the electrics...
