Good work, and that's an interesting solution to the colour.
I can't help thinking it would be easier to use an LED which lights up in a colour that is close to the original. LEDs are available in a wide spectrum of colours now, so there's bound to be one out there that's close.
A blue silicone boot won't make an incandescent bulb shine pure blue anyway, as there's too much red content in incandescent light, so finding a correctly coloured LED would produce a better colour than original.
Yeah I totally agree matey. It seems there are a few ways to skin this cat. The fleebay seller I used does offer a variety of colours so for anyone who may be interested I bought mine from “thestockroom101” and I can say I’ve used 5/6 of them so far and they all work fine, although I’ve not done any long term testing yet so can’t vouch for durability yet.
Also I think Nodge is right about blue, it simply acts as a light reducer without changing the colour.
I was also thinking if anyone doesn’t fancy taking their switch apart then I’ll will send out working refurbished replacements for free to anyone who is willing to post me their broken one so I have new ones to refurbish as it’ll save me doing more breakers runs for bits.
Cheers folks
