I ordered these bulbs because I had problems with my rule with original bulbs even at twilight in combination. Here, perhaps, it should be noted that I an old Fiat Bravo Year 1997 drive. The illumination of the previously installed pear was rather modest. An indication of other Bravos I can not do because I do not know what these bulbs in the headlights. The light itself is no longer dark yellowish special white and bright! I've read through a few reviews and thought at first that that was usually exaggerated. Anyway, I can say that these reviews quite truthful. The light cone is slightly wider and further. Now you see more in the critical zone at the edge of the road (see wild animals). One sees at night now super. Previously I had installed no other lamps, so I give "only" four stars. Nevertheless, I would recommend these lamps with a clear conscience!
It should be noted is perhaps something to the content. It's not just the H1 in the scope of supply also included two parking light bulbs! These are also colored blue.
So accesses, are you doing here absolutely nothing wrong. :-)
