It was a cermony where you have a large arrow, made from wood, like a 2x4, with seven candles. With a little more skill you could make it look more like the real ARROW of light, and add the arch/sun. You start in a almost dark room with ONLY the spirit candle burning, and read the explanation of the arrow of light, and the meaning of each of the seven rays.

I then would present an arrow to each webelos, with a attached feather that would have his name, and the date of the ceremony. The badge would go to his mom, to present to the scout, and the card to his dad, to present to the scout.

I recently saw an electric version of the arrow, with electric candles that we lit by some remote "magic".

I might add that you may be able to get some help from you local Order of the Arrow chapter to help present the arrows. It adds a nice touch to have the arrows presented by a scout in indian dress. Our chapter used to have a cermony all prepared.
