The power light does change colors but I don't know what the colors indicate? Charging/battery status?

It only changes color when you are running out of battery. You can check out some reviews of the speaker: http://www.techwalls.com/logitech-x300-wireless-stereo-speaker-review-beautiful-sound/ http://www.cnet.com/products/logitech-x300-mobile-wireless-stereo-speaker/

If the light comes on red then you have the right contacts, if it is plugged into the wall it will charge but there is no indicator aside from the red light. It will change to blue when it is charged.

There should be two positive/negative contact markings on the battery. Make sure those line up with the contacts on the charger. The light should turn purple once an uncharged battery is put in correctly. When not charging a battery the light will be blue. Here's a picture: http://imgur.com/uYFAktx . It's upside down in that photo to accomodate my other plugs, but you can see how the battery is oriented.

Mine doesn't appear to change colors. I let it charge over night and noticed in the morning there is no. the red light went out not replaced by a green. The charge seems to last a few days.

On the charging plug to the electrical outlet there is an LED light that turns orange when charging and then green when charged.

When its fully charged it turns blue. Otherwise the light is supposed to be pink

Hi Tom, when charging, the recriver light show red, and if full charged, it will turn to blue.

I think it's when you turn the power on and the light is red instead of green. Just happened to me. I changed the batteries and the light turned green.

Red light just shows that power is on. When the light is blinking it is charging. It will be steady green when it's fully charged.

The indicator light does change to show that the battery is fully charged. I haven't used my charger in a couple months. So, I don't recall exactly what the light does. If memory serves me well, it actually blinks red when charging, and shows solid green when it is done charging.

When you plug it in with a dead battery, the light should be red., When it is done charging, the light will be green. If your charger does not do this, you have a bad charger. I had bought a lower priced model, and it did not work. So be sure to get a quality charger.

the light on the charger turns a different color other than what it is when you hook it up. either red to green or green to red.

Try using a multimeter to verify the power... if that is not an option look at the wiring in the light you removed/are replacing. Check the 12v breaker box and see if you can determine the the color pattern used for wiring.

There is an LED light. It's green when they are ready to provide charging, orange (hard to see it different than red) when the batteries are low, and red when the batteries don't have enough charge to charge something. It stops charging the batteries when they are full. The light also says when the batteries are done charging. It blinks when they are charging. What the light says is printed in the bottom of the unit.

Either you connected it wrong, or you have a dead battery. The two lights should be indicating a problem with charging.

It should only be blue when it's plugged in with no battery. It should turn red/purple when it's charging and then red/blue when it's charged. I use more almost every day and mine works fine. Maybe contract anker about a replacement?
