[New, Unused] Koito Manufacturing Co., Ltd. Small Vessel Type 2 Red Light "MLE-3A1" "MLE-3B1"

This is a set of four signal lights for small vessels manufactured by Koito Manufacturing Co., Ltd. (KOITO): three Model MLE-3A1 and one Model MLE-3B.
The MLE-3A1 and MLE-3B have the same external dimensions and size, with the only difference being the bulb wattage (12V 30W for MLE-3A1 and 24V 10W for MLE-3B).
(The MLE-3B has been modified by replacing the 24V 10W bulb with a 12V 30W bulb to match the MLE-3A specification.)

This product is a legally mandated navigation light to be displayed at night when a vessel becomes disabled or restricted in its ability to maneuver. It emits a red light visible in all directions (360 degrees). These lights are typically required in pairs for vessels 12 meters or longer.

The connectors used appear to be equivalent to Yazaki Corporation's 250-type CN(A) 2-pin coupler. If so, they are available on Amazon for approximately ¥180 per set of terminals. Please verify the specifications before purchasing.
