In this tutorial, we will show how to make a traffic signal model for school science projects or exhibitions by using waste material available at home.
Traffic lights are located at road crossings and other locations to control the traffic. Traffic lights contain three colored lights.
- ( Red: to stop )
- ( Yellow: be ready to be )
- ( Green: allows traffic to flow )
You will need the following essential supplies to make your traffic signal model.
- 7v Battery
- LED bulb(red, green, yellow)
- Electric wire
- Waste cardboard
- white chart paper
- Sketch pens
- Colour paint/brushes
- Hot glue gun
Steps To Make A Traffic Signal Model
Step 1: Take one cardboard of size 250×220 cm and 4 small-sized cardboard of size 110× 8.5 cm.
Step 2: Attach a small Cardboard in the corner and cut them by making a circle at the center, painting paint/brushes, and painting them green.
Cut out a circle in the center
Step 3: Using Fevicol, stick black paper in the center and edges to make a road( as shown in the picture).
Stick black paper
Step 4: Add some buildings, plants, and white strips to the road for decoration.
Step 5: Now, for the traffic signal, take a small rectangular shaped cardboard and paste brown paper in it and stick red, yellow, and green circles in it.

Step 6: Now add small colored led to colored circles respectively and add wire ( as shown in picture).
Making wire connections
Step 7: Attach a small Cardboard of the size of LED cardboard to make a closed box.
Step 8: Attach a straw to the box to make a stand and paste it in the center of the road using a glue gun. And in one of the areas, attach a battery and a small switch and Connect a wire to it. Now, the traffic signal science model is ready for exhibition.
Traffic Signal Model
It is essential to understand traffic signals and the meaning of every color. It helps us to avoid unnecessary accidents.
This topic helps students learn how traffic signals and their rules work and help demonstrate how to make traffic signal models by using LEDs at home.
Things To Remember
- Working slowly and carefully during the cutover.
- Put a self-healing mat to save your base.
- Learn all you can about the materials and techniques you’re using.
- Work carefully during wire attachment.
- You should keep away materials ( Box cutter, in case you’re using a glue gun ) children out of their sight and reach.
