I have recently changed front signal light bulbs at the shop. After that I constantly have the light failure bulb on instrument cluster lightening when I turn on the headlights at night. I am sure they messed up with turn signal bulbs although they work fine. Otherwise there is no failure in any bulbs and everything is working fine.

Does anyone now what kind of bulbs are used in front turn signal lights (the ones bellow bumper)?

Thanks,
