When i started the car and drove it i noticed that speedometer, tachometer, windows turn signals did not work and after 20 min battery run out. before the drive I tried to change knock sensor but unsuccessfully because couldn't unbolt it so just let it be for a day, then i changed headlights for the new aftermarket angel eyes and then I started the trip. All the fuses look fine so don't know what the problem is. Maybe some wires are damaged, maybe alternator( but the day before it was working great and it would't explain the speedometer). if someone had the same problem pleas help 

Recheck your connection that you made and anything disconnected.

Pretty sure it's a maintenance induced fault.  Recheck the fuses as well.  

Could be a grounding issue also.
