Better H7 pears for Spacetourer + Dachreling

Hello all, there are not so many threats to the new space tourer. I have only had my 180HDI EAT8 for a few days, therefore the 2 questions: – the standard light the ST is not exactly intoxicating. It is a GE H7 L bulb. Does someone already have experience with other, lighter (and approved) pears? – Is there a roof rail (in the longitudinal direction) that hides the ugly welded metal flaps on the roof? Best regards Superpiet
