1:18 scale deck lights?

Hi everyone. I’ve just bought one of the basic Hot Wheels 1:18 Ecto-1 models. I would have loved the Elite but couldn’t justify the cost. I can easily add some paint details to improve the logo, tail-lights etc, but I hadn’t realised that the four deck lights were completely absent (http://www.gbfans.com/equipment/ectomobile/unity-deck-lights/).

Does anyone have any suggestions for a mod to add them? Any spare model kit or Diecast model parts I could cannibalise?

Thank you!

Try policecarmodels.com, they have all sorts of lights and light bars in various scales!
