How Light Up T-shirts Work


Our LED light up shirts use a thin ” Electroluminescent” or “EL” Panel that is attached to the t-shirt. The El panel connects to a battery pack that sits in a special pocket in the shirt. The sound activated shirts, can light up in response to music or any noise, and the auto shirts can light up automatically in different patterns.

  • Thin and Flexible Panel

    El panels are thin, flexible and water resistant. They are incredibly lightweight as the material is thinner than a credit card.

  • Design Is Always Visible

    You can always see the design that is printed on the panel. The technology works through backlighting where it will illuminate the colors in the design when the battery pack is turned on. When it is turned off you can still see the design printed it just won’t light up.

  • Connecting Plug

    This is where the battery pack plugs into the panel. You can also plug the connection in the other way and it will light up in the opposite direction

  • Fabric Sleeve

    This sleeve made of soft cotton material covers the thin wire from the battery pack so you don’t feel it on your skin

  • Battery Pack Pocket

    This pocket is hidden inside the shirt. You can also take the battery pack out of the pocket and clip it to your pants belt buckle or in your own pocket of your pants

Panel Attachment

Sewn On

(Recommended)

We typically recommend sewn on panels to the shirt because they look more professional and don't stick out like the velcro option. These are handwash only or dry cleanable once you remove the battery pack. 

Velcro-ed

The other option is to velcro the panel onto the shirt. Velcro does tend to stick out more than the sewn on ones because you have the added layer of velcro in between the panel. These are machine washable. Carefully unplug the connection from the panel and take out the battery pack and peel off the velcro-ed panel and you can throw the shirt in the machine wash.
