I had long been looking for a set of daytime running lights (DRL); but never was able to really decide because I wanted to integrate as possible with the front end of my Zafira A. The Daylight4 (with holders) fit into the height right between the ribs of the lower grille. I had to remove only on either side of a vertical plastic brace with a small hacksaw. The stability of the grill is not affected. The complete installation incl. Remove the ribs, lay the connecting lines and electrical connection was completed in about 2.5 hours. The quality and the pack contents (even cable ties are plentiful here) is actually outstanding. The TFL with plenty of long cables can be connected via connectors to a small black box. After only three cable (Plus, mass & control cable) to connect to the enclosed instructions. So I can just recommend Daylight4 !!!
