 if( digitalRead( myButtonPin == LOW ) {  // button wired so LOW = PRESSED..
      myTimer = millis() ;
	  digitalWrite( myLedPin, HIGH ) ;  // LED wired so HIGH = ON
   }
   if ( digitalRead( myLedPin ) == HIGH && millis() - myTimer > 5000 ) {
      digitalWrite( myLedPin, LOW ) ;
   }

Thank you very much for this. I will test it tomorrow it is very late where I Live. I will keep you updated
