Unplug it from the wall to get rid of the FF. This is the only thing I find annoying with my favorite ever heating pad used daily.

Mine only heats if you have heavy cover on it & then in spots. Some spots are cold.

Unplug from wall socket, the check to make sure the button and the control isn't sticking. Plug it back in if still blinking call mfg..

It needs to be plugged all the way till it clicks. I had the same problem. It will also flash if there are too many things plugged into the outlet. Good luck

I have had it for few months and it works fine all colors flash as expected . my guess would be a possible malfunction , probably good idea to call them for replacement .

My vipertek is fully charged and it only fire off on one side. I don't think that it is a defect. I'll get my husband to look at it.

I think you may have defective product. I just plugged mine in and worked right away. Just contact amazon and get replacement sent

Have you considered that it may be just broken ? It should light up right when you plug it in. Play with the sensitivity ... If still nothing them obviously it's broken.

First, make sure BOTH plugs are plugged in. Mine won't work with only one. The only other thing I can think of would be to restart with it connected. Unless you're running Linux. If so you probably have to mount it.

Sounds like a loose wire. I did have another brand of led side marker light that did that. After I tried everything I reversed polarity and it worked. Just a though if you haven't found the cause.

It is probably broken or your GFI outlet has been tripped. Does it make any noise and still light up? Use your warranty to get a new one.

OK just bought these and had the same problem. The simple fix for me was the 3 position color switch on the side was set to the middle position - which equals off. Once I slide the switch to either blue or green, they both worked fine. Hope this helps.

There should be a little red light that turns on and it flashes until it goes solid that means its ready. If the light doesn't turn on and it doesn't get hot then it doesn't work. I would send it back for a new one. There should be a warrenty.

I have two different Streamlights and each one was different . Try putting the battery in each way till it works and charges Sorry I can't be more positive.

I don't have a clue why but my first one sparked when I plugged in an aux source and didn't work. It was RMA'd and the new one worked and is still working great. Besides the bummer of having to wait for a working one I also had to pay for th ereturn mail. Still, the one that's working is really great. Get an RMA and send it back for a new one.
