    • 1994, Stephen Fry, The Hippopotamus, chapter 2:
      At the very moment he cried out, David realised that what he had run into was only the Christmas tree. Disgusted with himself at such cowardice, he spat a needle from his mouth, stepped back from the tree and listened. There were no sounds of any movement upstairs: no shouts, no sleepy grumbles, only a gentle tinkle from the decorations as the tree had recovered from the collision.
  2. (racing) A pole with lights, similar to a traffic signal, used for signalling the start of an automobile race.
    • 1990 January, Popular Mechanics, volume 167, number 1, page 96:
      Then, after a smoky-burnout to warm up the tires, you're lined up next to another competitor and the Christmas tree lights blink down... yellow, yellow, yellow, green!

      Wellheads, which support downhole tubing, casing, and other components, are connected at the top of wells to Christmas trees, which control production rates and fluid flows out of the well and may also direct fluids and equipment into the well
  4. (bodybuilding) A pattern of muscles visible in the lower back, resembling in outline the shape of a conifer.
