How to replace light part in Kenmore Vacuum 11625915507 Telescoping Wand?

Purchased the replacement part from Sears and there is no directions in manual or with part. The light comes attached to what appears like a large circuit board and I have no idea how this large piece fits into the narrow wand. I assumed it would just be a quick replacement of the bulbs but obviously way more complicated than that. Have no idea where to begin to disassemble.
