This is a very basic motorized kit.The body is a bit oversized and the headlights are a bit small and are fixed in opened position.
Light bulbs for the headlights, very wide wheels, fancy decals and a big Mabuchi motor make this kit more of a toy than an accurate Rx-7 model.
Light bulbs and Mabuchi motor are included in the kit.
The kit was released several times, here's a picture of a different box top.
