Fiat Panda Electric Farm

Hello, I have a Fiat Panda of 2012, and sometimes the lights go out and then turn on again, this circulates scare and is dangerous, but in the workshop they tell me that they know it can be, you can help me?.
thank you

Check the command to see if it does not make good contact when lighting the lights, measuring continuity in the corresponding poles, also check the reverse of these as well as the wiring that activates the relief (if it comes current and if it is activated), the good contact of the fuse and the mass of the lights. It is a matter of discarding failures. In the workshop this should know how to do it, if not ... go workshop !! ... greetings !!
