Since the clocks went back I have been riding home in the dark using either an old Dinotte 5W or a Cateye HL-El320 or both. I got my system with two sets of AAs going for the Dinotte
Both of these are perfectly ok lights. For example the other day I had the Dinotte angled a bit high and a car flashed me presumably due to it's blinding laser properties
But the IQ Fly is in another league. I can really see the potholes and road mess before I get to it.
I feel much safer and comfortable with this proper light. And there is no problem with fading lights due to failing batteries
