I've been using black diamond headlamps. In recent years they replaced their battery indicator LEDs to some really strong blue ones. I use the red light a lot, and when I turn it off, the battery indicator LEDs will light up the entire room. I have covered mine with electrical tape, but the blue light shines through the plastic so it doesn't really work and my headlamp looks ugly. I don't know why they would do this. The first headlamp I got from them had red, yellow and green battery indicator LEDs, now they have 3 blue ones. It's really annoying. I should probably write them an email and ask them to fix it.
