I put the batteries in but the lights never worked...any tricks to that?

I had several issues with this item, so I returned it. I know that doesn't respond to your question exactly, but that's all I can tell you.

Unscrew the small end. you will have to test it to see which way the batteries have to be turned but if you try both ways and you still have no light the bulb may be bad. Mine worked fine.

I would make sure those batteries are recommended for the light. I would also make sure they are installed properly. Some batteries are also required to charge a certain amount of time before you can use them. The batteries could be defective. I would take them somewhere like Batteries Plus and have them test the batteries. Hope this helps.

Not to start off sounding like a smart a** but make sure it's plugged in to a working outlet. Second push the button on top once. If you can't tell if it's working turn the lights off. You should see a faint bluish glow in the dark.

I would return it if it is not even lighting up. Mine works well with the batteries. It sounds like something might be wrong with the unit. It has to light up to work. Good Luck!but

It must be broken - if you put new batteries in, should work. Contact seller.

When I first put in the batteries, it did not work. I realized that I put the battery holder in the wrong way. Turned it around and it worked. Hope it's that simple!

Either the batteries are not in the right direction or the lamp is defective. Make sure the flat side of the battery is the one in contact with the springs, there are 2 up and 1 down. The cartridge that holds the batteries has arrows on the side (not easy to see). Make sure that's the direction you introduce it in the lamp. The tip (of the arrow) enters first and then just screw (the bottom cap).It emits enough blue light that you'll know if it works or not.

I see no way to put batteries in, but the lights are fading. I have had it for a couple of months

I bought them too. The batteries are probably dead. A similar thing happened to me. Mine lasted a couple of weeks with occasional use. Because they are "wireless", the system is always active even though the lights aren't on, looking for a signal to come on. Had I known of the short battery life BEFORE I purchased them, I wouldn't have bought them. Good luck to you.

My light never worked from day 1. It takes two AAA's. One of them sort of balances in there held in place by the spring, any movement of the whole thing shakes the battery loose.But even when I held the batteries in place the light never worked.

It never worked for me, I tried all I could think of but nothing. No lights ever came on, it was dead on arrival. Hope that helps.

Try with the switch on the light assembly in all positions, if still not working recheck the wiring connections. After that I would probably follow procedures for returning a defective unit.

If you have access to a multimeter check to make sure your batteries are actually charged. If not maybe someone you know can help you or perhaps visit a local electrical supply store, Radio Shack, etc. If the batteries are fully charged, do make sure you have then installed correctly. I can't tell you how many times I've installed batteries incorrectly even though I absolutely know to check which way they go before I put them in. If your batteries are charged and they're installed correctly, then I can only assume it has something to do with the circuitry of your headlight.....could be a lot of things. Sorry to tell you that my headlight did not last long and its problem was poor quality circuitry....the circuit board in the battery compartment self-destructed. It fried itself one day while I was wearing it. If your light is now garbage, try this one: Weiita H807 Starlight LED Headlamp, 300 Lumen, available on Amazon. It's similar but much better IMO, plus the company is great to deal with. Hope this helps.

Make sure your batteries are correctly installed and then plug it into the provided charger. I charged mine when I received it. Also check all battery compartment connections. I had a slightly bent connector. If it fails to work after that I would defiantly as to exchange it. They really are great headlamps. Despite some of the minor issues.

At the Batteries Store. These little lights are not dependable and only about half of them work. Good Luck.
