I've also noticed something I did not expect. Before installing the chip I could not turn the lights on or off. I asked the shop that sold the bike and they told me: "Yea, we know and there is nothing we can do about it".
It's a standard Bosch dealer laptop thing to activate the lights with their laptop/software thing.
If they are a Bosch servicer and can't do that then you need a new store and pronto.
