Step 2: Modify your pumpkin (be it art or actual) to fit the tip of the 5 MM LEDs.
As a ballpark idea, the size of the LED tip that you will need to install inside your source you'd like to light up is slightly smaller than the diameter of a pencil.
So, if a pencil can fit inside, you can easily mount / stick the LED in and mount it (be it with sealant or glue, but let's not get ahead of ourselves!)
I used a handy metal instrument to insert into the source and pry a proper opening that allowed the LED to fit snugly, in the next step we'll group together the 12V Prewired RGB LED wires (simply ground and power) & then install and mount the LEDs.
It's that easy! Next, let's group the wiring together and mount them inside the art-work / pumpkins!
Oznium has already done all of the wiring of the RGB controller, resistor & polarity protection inside the wiring!
