This speaker comes equipped with a set of party LED lights that, by default, blink, scan, and pulsate in all sorts of colors to the beat of whatever you play on the speaker. But now and then, you may not wish to have a party atmosphere in your room, like when you want to play the speaker while drifting off to sleep or during the day in a bright area, where you can’t see the lights anyhow. So we give here the Sony SRS XB33 Turn OFF Lights procedure to use, for just these situations.
To turn off the lights, you need to find the LIGHT-BATT button. We find this control on the back of the speaker, inside the ports compartment, as we see in the next picture.

Sony SRS XB33 Turn Off Lights, Step by Step
These lamps, which light the interior of the two speakers on the front of the unit as well as others that illuminate the left and right edges are set to display their party show by default. They work either when fresh out of the box, or after a factory reset. You can turn them off as follows…
- Open the port compartment cap at the back of the speaker with a nickel or dull butter knife. Avoid using sharp objects here.
- Turn them off by pressing the LIGHT-BATT button for three seconds. Doing so may save a bit of battery power, especially when you don’t really need to waste any on running these lamps. E.g. Like when playing the speaker in daylight or in a bright room where the lights would be harder to see anyway. In the next picture, we show what the XB33 looks like with its lights OFF.

Then when you want to turn them back on again, simply repeat what you did above. I.e. Press and hold in the LIGHT-BATT button for three seconds. Then the party lamps will go back to their usual pulsing and fading color changes.
