Failure warning

Hello everyone, my car is a 2007 model 207 and has xenon headlights on the front. However, when I press the brakes and give the signal, it keeps giving the warnings of log lamp, brake lamp, fault indicator, fault. I installed all the new lights, and they are all active. I couldn't solve it. Please help me.

There might be a problem with the sockets, brother. Check the sockets one by one. Their feet, etc., are oxidized. There's a short circuit somewhere.
