If it’s going to be your only light (on your helmet) I would look for something that doesn’t give a tight beam as you won’t see much if you turn your head.
For £50 you could probably get a couple of cheap Chinese lights linked in that link up there ^ and have one on bars/one on helmet. Just running one light on either is a bit of a compromise IMO.
I’ve managed to get a used exposure maxx d main light of a mate. So just looking for a helmet light good enough to start. I appreciate the links and response
As Stevie says, a couple of the cheapo chinese ones (i use 4X Cree XML T6) will do just dandy. I think mine were £32 for the pair. You can butcher the headstrap to make it work as a helmet mount too.
Compared to some of the lights you see on here they seem feeble but in reality, they work a treat and give plenty of light. They don’t turn night into day like some do, but i don’t really want that on a night ride, i just want to see where i’m going. I found setting the bar mounted light to medium and pointing it a few metres from the front wheel and the head one on full whammo pointing up the trail a bit give a very usable and even corridor of light to play in.
