How to put it together
- 1
Put on the black long-sleeve shirt and black pants to create a neutral, dark background.
- 2
Prepare your tunic base, ensuring the armholes and neck opening are wide enough for comfortable movement.
- 3
Attach the three colored circles vertically down the front of the tunic: red at the top, yellow in the middle, and green at the bottom.
- 4
If using LED puck lights, mount them securely to the center of each circle using strong double-sided tape or hook-and-loop fasteners.
- 5
Slip the completed tunic over your head and adjust it so it hangs straight down your torso.
Makeup & hair
Keep hair simple and neat. No specific makeup is required, but you can paint small red, yellow, and green dots on your cheeks for a playful touch.

Traffic Light costume FAQ
- How do you make a DIY traffic light costume light up?
- Use battery-operated LED puck lights or tap lights. Stick them to the center of your colored circles, or mount them behind translucent colored plastic plates.
- What color should the background of the traffic light be?
- While real traffic lights are usually yellow or black, a black background makes the red, yellow, and green circles stand out the most.
