Did not get an instruction sheet for this 18650 headlamp. What does "red light on battery pack flashing every few seconds" mean?

I didn't know what it was for either until one day the light fell off my head in a dark crawl space and I had to go looking for it in the dark. Then I was very thankful for the red blinking light. Also, I think it is to let you know that the battery is not dead.

I didn't get instructions with my light. The blinking red light seems to mean it has a charged battery ready for use. I take the battery out when I'm not using or charging the it. I use mine for work the battery lasts 2 to 3 hours of steady on. Longer if use is intermediate.

It is a safety feature, it is used so the person walking behind you does not get lost either in the woods or in a cave. for me I go walking early in the morning in a nearby road I want that drivers can see me by the red blinking light or by the bright front one.

It flashes even with the lamp off. I always assumed it just showed the lamp was powered and good to go. I know it is solid red when charging and turns green when charged. I personally use my head lamp when I work in dark spots not for rock climbing or biking.

Probably the battery. I have had issues with it after purchasing the lamp. You should call the company. They have shown they have an outstanding customer service. They replaced the entire head when I contacted them.

I would suggest you make your own battery pack or buy a different light. My battery pack was dead on arrival. I haven't opened mine up, I started to pull the rubber stand off to get to the batt pack but it's glued on. It'll be damaged if I can't find another way. It's probably got 3 AA cells wired in series to give 7.2V. If I can't hack this to use AA or AAA 'Eneloop' batteries I will dispose of it.

i get the red light all the time it just indicates that the battery is way way too discharged

The instruction booklet states there will be a lag time between entering your code & the door unlocking when the battery is getting low. That's supposed to be your sign to change the battery. I didn't see anything about a red flashing light, but I could have skipped over that. It's a pretty short manual, tho! lol

Mine was defective and returned. Sounds like yours is too, so return it if within the 30-day Amazon window (very easy and FREE). Then go to your local "HD" hardware store and spend your $13 on the "Rayovac DIYHPHL-B Indestructible 100 Lumen Headlight with Batteries." It's a FAR better lamp with none of the many problems of this no-name rechargeable lamp. It uses standard alkaline batteries, but will take rechargeables too (3xAAA). Amazon stopped carrying this model due to mis-packaging, but the HD store has no such problem. This lamp is VERY powerful, and the narrow beam goes out 100 yards (perfect for night biking). Also has a low beam for closer work. Go get one! Mine was defective and returned. Sounds like yours is too, so return it if within the 30-day Amazon window (very easy and FREE).

Hi Eugene, have bought the same unit, no problem so far. The blue light glows whilst it is charging. I would suggest checking you do not have a faulty battery first, all the battery polarities are correct otherwise it sounds like a fault in the lamp controller. Good luck! Apart from being a little heavy and not particularly pretty this is a great bike lamp, actually lights up the road.

If you look on the label at the end of the charger, you will find in the upper right corner (in very small print) a graphic description of the various light conditions that indicate the state of charge, delay, bad battery, etc. The length of the lines indicates the relative time the light is on. If this is missing or unreadable, I suggest you search online for the user manual or whatever. Dewalt should have something on their site to help, also. Hope this helps.

Perhaps they have changed something but ours does not have a red light. Perhaps the flashing red means it is heating. Does it heat up? Did you try a different setting rather than on high? I'd try to leave it on a couple hours to see what happens. If it does not go off, then malfunction.

On my unit the light is red, and it starts flashing red when I place a drained battery into it for charging. Once the battery is charged it turns green and stays green until I remove the battery to use it.

Ben, it is probably the type of battery. I had the same problem with a flashlight,and had to get batteries from Hong Kong to get the light to work.

It seems 'Not'. But when the battery pack is being charged the lights are on - blinking. After push the round button you will see the some of 4 lights on and know how much power left in the battery pack.

I would first take it apart and check the circuit to see if the problem is due to a false connection or other, as it is often with these products. Other than that, go to Kaidomain.com and order the: 9 LED series 5 mode low voltage protection circuit for $20.38 SKU# S020909.You will have a much brighter flashlight with this driver, good luck, hope this helps.

The battery is an 18650. They are like giant AA batteries. You can usually pick up a couple of them and a charger for about $10 online. Initially it may seem like a lot but since they are rechargeable they will pay for themselves. The reason they use these batteries is because they are rated for 3.7 volts (instead of your typical 1.5volts). This means the led can put out more light!!

1. Test the "new" batteries individually to make sure they are OK. 2. Confirm that each battery is installed correctly into the holder - the flat (-) end of each battery should be towards the spring in the holder. 3. Confirm that the battery holder is installed correctly into the flashlight - the holder goes in "bump" end first. If your flashlight still isn't working, then either the on/off switch or the LEDs have failed, and these are not user-replaceable.

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.

Mine has a red yellow and green light across the top and in the shape of a small battery. This is to ley you know you know the condition of the battery. Red is needing charge,yellow is to let you know caution and the green is full charge. And none should be lit unless you press the check battery button. I hope this helps answer your question!!!!
