German native speaker here with lots of assumptions. For the first word, "spitze" can be "peak", but also the pattern/cloth as seen when you google doily. In this context, that's probably what he means. That means the "s" belongs together with the "parken", making it the English "spark". "sparken" could be "making sparks" For the second word "Blinklicht" ist "blinking light", "Blinklichtchen" would be the diminutive, it's probably written "Blinkelichtzen" to make it look ever more German. He appears to be kind of an unpleasant person.
