Mounting 1/10th 959 Dakar Lights tip

Here is a quick tip for mounting the light bowls to your 1/10th Rothmans Porsche 959 Dakar shell that is quick, avoids messy glue, and works great.
When you cut the black vinyl to attach the reflector to the light bowl leave 10mm extra around the mating edge. Radially cut this to create a fan of vinyl strips, which will then fix the light assembly in the body. Hopefully the pics will explain where I have failed.
