Unfortunately, the plastic on *some* of these LEDs is backwards, and we didn’t catch it before they shipped. I apologize for this; we probably should have noticed and included an erratum with the kit about it.
The correct solution is to install the LED as instructed, with the long lead into the square hole. However, the plastic may be backwards from how it is pictured.
