Tail Light Issues

[cjhs23sg]

ok when i bought my 92 190E 2.6 all lights worked fine then all of sudden one day my tail lights were all out of wack - my brake lights work but they light up in different spots then they should (left is a white light - right is yellow) and blinkers do all work is there any reasoning behind it or does any1 know somethin i dont - because if a light burnt out why does the other come on wrong any help would be greatly appreciated
