Lights Flickering

i have two 14500 lights -- a C3 and S10 -- and both (especially the C3) have an intermittent flickering issue. it's a high-speed flicker and shaking or tapping the light usually fixes it. i think something may be loose inside, but i have no clue as to the inner workings of these things. any ideas or suggestions?

make sure all contacts are clean and it is all screwed together properly   try tightening the switch i have had a few lights with similar faults and it is usually somthing not tightened properly

Sometimes it´s the contact between the clicky and the spring to battery -.

I had this problem on Eastward YJ J08.

The spring is soldered separately and contact is only 100%, if this 2 parts pressed togehter.

If tailcap was screwed out (only a little, little bit) contact can be interrupted.

The C3 is primarily dependent upon the body biting into two solder blobs on the head - they can give trouble.

The numbers from my light tests are always to be found here.

Tail first .. I have a small victorionox knife with small sicissors on my key chain and i use them spread out to hit each hole and crank the tail cap tighter .in my experiance that is 85% of it right there... if it's loose at all  then it's the cure .. the heads more of a pain  one  thing is the reflector mashing / over mashing the emitter .. some lights want it to happen some lights no,as it short out the emitter , solder blobs of course as was stated by don ..  try the tail first  try jumping around the tail with a paperclip or a wire to make sure .. to isolate the problem ...OR  Buy 20 more  lights ...  < most widly used  method on BLF
