How to put it together

1
Put on the black hoodie and sweatpants to map out where the LED strips will go.
2
Lay the clothing flat on a table and plan the routing of the LED strips along the limbs, torso, and hood to create a stick-figure outline.
3
Secure the LED strips to the fabric using heavy-duty clear tape, safety pins, or hook-and-loop strips, ensuring the wires point toward your pockets.
4
Thread the power cables through the pocket openings or small, discreet slits cut into the inside of the hoodie and pants.
5
Connect the LED USB cables to the portable power bank and place the power bank securely inside your pocket.
6
Put on the clothing carefully to avoid pulling or straining the light strip connections.
7
Put on the LED glasses, turn on the battery packs, and select your favorite color or flashing mode.

Makeup & hair

Keep hair pulled back or tucked into the hoodie. If desired, use UV-reactive neon face paint that glows under blacklight to complement the LED theme.

LED Light-Up for couples, groups, kids & more

couples: One person wears blue LEDs and the other wears pink or red LEDs for a glowing neon duo.

Tips

Test your LED strips and battery packs before attaching them to the clothing to ensure all connections work.
Bring spare AA batteries or a backup fully-charged USB power bank so your costume doesn't go dark mid-event.
Avoid bending the LED strips at sharp 90-degree angles; loop them gently at the joints (elbows and knees) to prevent breaking the internal circuitry.
Wear comfortable sneakers, as this costume is highly popular for dancing and walking around at night.
