There are LEDs and then there are Build Upons LEDs. Each Build Upons PTH LED in this 10 pack are brick shaped in the same form of your favorite construction block! These LEDs can be easily used as novelty indicator lights, or ground effects for your existing brick sets as the tops of each LED is compatible with LEGO® bricks.

The Build Upons pack contains two diffused PTH LEDs of red, blue, yellow, green, and white. Each LED (minus the leads) are the exact same size as a LEGO® 1x1 brick. Only the tops of the Build Upons LEDs are stackable, not on the bottom due to protruding through-hole leads like any other PTH LED.
