Tail & brake light bulb, front blinker light bulb

[ZR468]

I am confused. Does anyone know the model numbers of the subject light bulbs? I looked in the Kawasaki repair manual and the owners manual, they don't really say. Will a pair of P21/5W replace the tail light?
Are the tail light bulb and the front blinker light bulb interchangeable? Here in Canada, the front blinker lights stays lite when the bike is on, then it blinks when the driver turn on the turn signal.
Thank you in advance, Kenny
Ps , it is for a 1992 ZR750C

According to the online part list European Zephyr 750 tail light bulb is 21/5W, while 27/8W bulbs are indicated for Canadian tail lights and 23/8W for turn lights. But all these bulbs look similar: same dimensions, same bases, same contacts. So yes, they are interchangeable.
