Pokryshkin P-39N

[fovcollector]

Looking through books I see some P-39 have 3 identification lights only under the right wing. They are red, blue-green and amber running front to back. I have never seen Pokryshkin P-39 drawings with these lights, did his plane have them but people just don't draw them or if they do they don't seem to add color they just look like 3 small circles. I want to be accurate so I need to know whether or not I should add these 3 colored lights.
Thanks.
