Hi, thank you for your question. Our 2-Packs of Pico LEDs include one 1:2 adapter. So you could buy a 2-pack of Pico LEDs in the color you needed, and you'll get a 1:2 adapter included. If you need to light a small model, you might also look at our Headlight Kit, which can be used with any small setup. It includes a battery pack, two warm white Pico LEDs, and a 1:4 adapter. We've had many people use this for small buildings and other things besides just vehicles.
