Abstract
End of train marker light equipment (10) has been designed with a battery compartment (13) which can receive either a lead/acid battery (100), a Ni/Cd battery pack (250) or a pair of lantern batteries (350 and 352). In a first configuration, the lead/acid battery (100) mates with an electrical connector (30) positioned on the back wall (20) of the battery compartment (13). In a second configuration, an adapter (200) is fitted into the battery compartment (13) to receive a Ni/Cd battery pack (250). The adapter (200) includes an electrical connector (218) which is copmlimentary to the electrical connector (30). In a third configuration, a pair of lantern batteries (350 and 352) are fitted in the battery compartment (13) to contact a contact pattern (300) positioned on the back wall (20). One of the batteries (350) is fitted into the battery compartment (13) on its side while the other battery (352) is fitted into the battery compartment (13) at an angle with its edges cooperating with grooves (26 and 28) in the sidewalls (16 and 18).
