Northern Lights used this pocket guide as a great information piece. It is a technical date booklet that is power packed with information on all the generators and engines manufactured by Northern Lights. This pocket guide is a multi-paged document. It has a full color cover, and a two color inside in order to keep production cost down. It's sized perfectly to fit in to a back pocket.

A new pocket guide is produced twice a year. The red represented the summer printing, blue was the winter printing. The inside information was continually changing and being updated.
