I have e60 530i 272hp 2009 bmw and I saw today that there is 2 h8 bulbs that connected to harness does ant one knows how can I use them or for what they are?
just u to know my main lights low or high are xenon gas!

 

Do you mean inside the headlights? They can either be the flash to pass which turn on when you pull the lights stalk towards you however they are actually H7 the other option is you found the angel eyes bulb which I believe are in fact H8s
Ps. Some pictures could've been helpful
