How to Make a Simple Flashlight: 1 Minute to Create Your Own DIY Flashlight

Creating a simple flashlight is a fun and practical project that’s perfect for beginners and DIY enthusiasts alike. All you need are a few basic materials: a small LED bulb or torch bulb, a battery (such as AA or AAA), some electrical tape, and two wires. First, connect one wire from the positive end of the battery to one terminal of the bulb. Then, connect the second wire from the negative end of the battery to the other terminal. When you complete this circuit—either temporarily by touching the wires together, or by adding a switch—the bulb lights up, turning your setup into a functional flashlight.

Tips 1:

As a designer, I always recommend thinking about not just the technical aspects, but also how the flashlight feels in your hand and fits into your environment. To improve usability and style, consider crafting an outer casing from materials like cardboard tubes, recycled bottles, or even custom 3D-printed shells. Personalizing the casing lets you align your DIY flashlight with your home's interior aesthetic and creates a seamless [DIY room decor](https://www.coohom.com/case/diy-room-decor) accessory.
