NOTE: After you align and envelope the lights and rectangle, set the rectangle's outline to none.

Advance the frames until you come to the front view of the truck.

Create a rectangle the same size as the front of the truck as shown. Add two yellow headlights.

Group the rectangle and headlights and copy them to the clipboard.

Repeat the steps for reducing the width and applying the Mould > Default Perspective Envelope until all the front ends of the truck are covered.
