The asset is supplied as a set of 7 blocks parented to a collection empty. Each block consists of 6 objects: a chrome plastic frame, screws, internal LED fittings (+ 2 point lamps), and the coloured plastic. The plastic frames and colour plastic make use of the mirror modifier when possible. The point lamps are contained in their own collection so you can easily turn on or off the light with a single click (disable the collection). You can use the cable hook empties to adjust the power cable as required for your scene. 

Please note that if you wish to replace the materials you will need to UV unwrap the meshes.
