Yes and no. I do ride frequently on roads without streetlight. I notice that the main light from my previous bike only helped with lighting up traffic signs and other road signs. I did not get the good view that I expected. This is even more true for the Tenere head light.

I have seen that auxillary lights (think Touratech) are a big difference. I could switch to Xenon, but I do prefer the auxillary lights. The more lights one have, the higher chance that at least one is burning (in case of problems). I am saving some money for the TT stuff because they are expensive.
