I have one of the hope 4 lights. On recharging I plug it in, LED goes red, then back to green then red…
thinking it’s a connector issue but….
I suppose I could measure voltage across the circuit with the light attached…
any thoughts?

Contact hope, they are usually very good at sorting out issues in my experience.

If its an R4 then it’s not unusual. As above, contact Hope.

Connectors. Mine has been doing this for a while, rectified by charging using the extension lead that comes with it for putting the battery in your backpack, between the charger and the battery. Havent had chance send it back as need the lights all the time at the moment.

Mine is sorted with a wiggle and some patience but I have 3 mates that had to return theirs.

I’ll try using the extension though, cheers.
