They’ve improved those LED faucet lights to indicate whether the water is hot or cold. Or specifically, whether it’s warmer or cooler than 89 degrees.
I wonder if anyone makes one that’s continuously variable. This could be a good visual gauge of water temp, especially when preparing a bath for a small child.
There are shower heads that display total water volume and temperature as they change, on a screen,
and the colour of the screen (in the head) changes from blue to purple to red/orange with temperature.
Off the shelf from your local giant hardware store.
Are you a spammer ?
I think we have seen this guy before…spammer yes
I made an LED piss light… still going strong on its original set of batteries after two years. It’s one of the best/most used lights I ever did.
