PTT 3-light in-transit Kit, landing gear indicator lights, with in-transit light $195
PTT 2-light Kit, landing gear indicator lights $130
PTT Stall Kit, stall warning indicator light $65
PTT Fuel Kit, electric fuel pump indicator light $65

Notes: These kits do not have FAA approval; however they are manufactured from properly-marked MS22759/16 wire and MIL-SPEC indicators which are far superior to what Piper specified, as they should have installed originally. I have an approved 337, but not for duplication, which I include with each kit; maybe it will make your IA feel warm and fuzzy.
