Thanks for the LED light info.
Unfortunately, the LED light option suggested is quite a lot smaller than the original design.
I quite like the original size and design - they are very robust, much better than anything else we’ve seen elsewhere - it’s just that ours are brass and we want chrome or stainless steel.
Incidentally, “Calibra” are the UK distributors of the originals. Cabin Marine of Denmark are the manufacturers. Thanks again.
