Blue light means its charging a device. Red light means it no longer holds a charge, and you need to re-charge the battery.(Although my device has a red light when plugged in to re-charge) Not sure about how to keep it from wasting battery? I guess do not plug it into device until you need to recharge.

The red flashing light means the water is below water sensor -&gt; add more water. When the red light is constantly on, that means the diffuser has power and has enough water. If it doesn't turn on, 98% of the time, it's just low water. You need to fill above the metal sensor.

The Blinking red lights normally means that it is charging or need to be charged. When finished with charging the red light should disappear.

If you know what you are looking for, you can see the red, but I have had numerous people tell me that the lights are "burnt out" or not working. They didn't know that they were IR lights.

The warning lights are red. There are three white LEDs that can be used as a flashlight.

Hi Kathie,I believe the red light just means it's in standby mode. I have mine wired to my sound bar and when my sound bar is off, the light turns red. But when I turn the sound bar on, the subwoofer light turns to blue and it starts producing sound. Hope this helps!

This product does not contain a red light. It has two white light brightness levels, high and low. Hope this helps.

I wondered too and the answer is not in the manual which is just a paragraph or two. My guess is that the red light indicates the power is on and is recharging the battery. That makes most sense.

There are 2 lights. the red one indicates that the unit is plugged in. When it is charged, an additional red light comes on. I also must say that I love the speed and ease of using this charger. Keep it away from magnetic recording materials (credit cards, disk drives.) It is a ridiculously good deal, and I wish my ipad had a similar charger!

It means the battery is already charged. When the battery is charging, the light is red.

It is a very bright white light that casts light forward of the headlamp. There is peripheral red light that is noticeable, however does not cast any light forward. Personally, I seldom notice it when looking forward into the white light. If this bothers Tyler, simple wrap a piece of black friction tape or other opaque tape around the red ring. Guaranteed, you won't be bothered by the red light anymore.

UV light is not visible to the human eye so you shouldn't expect to 'see' anything. The red light means that it should be working, and as others have mentioned if you do have green water you should see noticeable results within a few days.

it means that your battery is running low and that it will be shutting off soon. I was on a night bike ride and I had the light setting on high then it was from green light to a red blinking light after 5 minutes it shut off.

It would seem the red light would be on when the lights are on. But, mine as yours, the red is in stand by or off and green when lights are turned on.
