I was part of a “focus group” just some random people that my friend and his team asked questions to about some humidifier or something, I genuinely don’t remember and he was shocked when I said I didn’t want ANY LED lights on the product and he’s like “how will you know it’s on??” On a product that would absolutely make noise while running. We compromised and I told him a completely hidden LED under the product, as long as it had no light leaks would be acceptable.
