Seriously, it’s the first time I haven’t backed off the speed due to lack of light.
for me when I first found trailtech HIDs and headmounted one was the first time I really felt I didn’t have to back off riding DH tracks at well known (to me) places like inners etc., IIRC they are around 500lumens (someone clever will no doubt confirm/correct) that must’ve been 10 years back and to this day I’m happy with that output on my head.
I know my local roads very well, there’s less to crash into and I’d still not even contemplate going for a ride without lights (and it’s nowt to do with fear of being run over!).
Funny you use that example, there’s one road climb on my local rural road route I nearly always switch my front light off for, I prob can’t explain exactly why, it just feels much nicer and makes me happy. you can see car headlights for miles so I’ll switch back to low setting if anything’s coming.
but to say that people don’t need lights at all if you know your trails is just daft IMO
don’t believe I suggested whether anyone else should or not. 😕 you do have a rather bad habit of making up stuff I haven’t actually said and then arguing with me about it tho.
