rear running(marker) lights not working

[Makedon]

Hello . I'm in a process of restoring a 2009 GZ250. One of the problems that I have is the rear running(marker) lights. I have tail and brake light( the red one), also I have turn signals left and right , but they are not On as a running(marker) lights. I check all the fuses under the seat(all good), clean bunch electrical connectors and plugs , but I can figure what is the problem. Also my front running(marker) lights and turn signals are working fine. Any and all suggestion and ideas are welcome. Thank you very much. Vlad aka Makedon. Ride safe.
