500pcs Assorted 5mm LED Kit – White, Red, Blue, Green & Yellow

LEDs are some of the most essential components in any maker’s toolkit. From simple Blink sketches to more complex circuits, this 500-piece kit equips your workspace with the most commonly used 5mm through-hole LEDs. Inside, you’ll find 100 LEDs of each colour: red, green, yellow, blue and white – all with a diffused lens for even, soft light distribution.

5mm through-hole LEDs are widely used in prototyping and DIY electronics. These LEDs fit easily into breadboards, can be soldered to veroboard, wired directly to GPIO pins, or panel-mounted as indicator lights in enclosures.

The assortment of five colours gives flexibility for signalling, feedback, lighting effects and more. Each LED operates reliably between 2.5–3V and works best at a current of 16–18mA, with a maximum rating of 20mA.

When using LEDs, it’s important to remember they are polarised components. The shorter leg is the cathode (GND/negative), and a current-limiting resistor should always be used in series to prevent damage. Our Ohm’s Law guide can help with choosing the right resistor for your voltage source.

This kit is a great way to stay stocked up for your next round of prototyping or creative builds. Whether you’re new to electronics or building your tenth custom PCB, these LEDs are ready to light the way.
