Ha you beat me to it! You could go smart arse and see if you can drill the centre out and drop a nice little led in there! If it's local and it's free then I know I'd be able to make something of it
Yeah just Wang it in there any I picked one up before, an old useless mare of mine managed to covert it to spring back (it's the only thing he's ever done that's impressed me!) And it still actually works! It's my horn
The switch already has illumination when on so surely you don't need led?. I used my front switch for the rear and although I haven't passed my mot yet, I didn't get any cautions. Maybe that was luck.
Mines a front fog switch just with a led so i know it's on and don't forget about it as I couldn't figure out how to illuminate it passed an mot with it
