Digital "Twist" flashlight skipping modes.

gunlock · Nov 28, 2009

Hey guys,

I tried searching for a solution but couldn't find much. I have a relatively new Fenix L0D Q4 mini flashlight with four modes. It operates by twisting the light on then off to toggle the different modes. What happens is that sometimes I attempt to toggle a mode and instead of going from mode 1 to mode 2 etc, it will skip to mode 3 or mode 4 completely, or briefly flash to mode 3, then go to mode 4. It's annoying. I tried using different batteries but that didn't help.

Any advice?

Thanks guys.

Sounds like a probem with the contact. Try cleaning it and looking for something loose or misaligned. I don't know the Fenix lights, but that seems to be the problem, in general, when that sort of thing happens.

Yeah, clean and re-lubed I say!

Indeed. You need to open the light and clean the parts that make electrical contact with each other. You can do this easily for the battery compartment by pressing it open-end-down onto a cleaning cloth and twisting. The corresponding contact ring inside the head is a little trickier to get at, but a cotton bud may do the trick.

Once cleaned up, you might be pleasantly surprised to find that you actually have five modes: med-low-high-strobe-sos.

I cleaned the terminal with a jewelry polishing cloth and that seemed to help a bit. Can you guys recommend a better/proper way to clean the contacts?

Also, as far as lubing, I have no idea what that entails. Any advice in regards to proper cleaning/lubing technique ya'll can offer would be much appreciated.

Thanks.

Good, glad it's working a bit better.

Best place to start for cleaning and lubing is here:

I just read through a bit of that thread you posted. Thank you. It seems a bit high level though and I was hoping to not have to go out and buy products that I will probably not use again any time soon. I've cleaned my threads and contacts with isopropyl alcohol on a q-tip. As for lubing, can I just use tetra grease, rem-oil, CLP or something like that which I already have laying around?

This is for a Fenix L0d light. I'm not sure what material the O-ring is made from.

Thanks,
