Question: How many AAA batteries required in this product, 2 or 3???
Document: That these are lights, WITH ADJUSTABLE SETTINGS, is top notch!There is additional cost involved, in that one must buy AAA batteries for the headlight and AAs for the taillight.The ONE negative is that there are NO instructions of any kind included with the product. So, it took additional time to become fully acquainted with the product components.All in all, it is a good purchase.
There are a number of sellers with the Sodial head and tail light combination at surprising price variations. I got mine from &#34;Digital Center,&#34; for only 3.82 and that included shipping, 6AAA batteries and no sales tax! It's not the highest quality looking product, but it works fine and that's all I need. WalMart wants 7.96 for the same item.
I am not sure yet.. The tail lights are powered by TWO AA batteries not the smaller AAA batteries which most lights now use. Due to the bigger batteries they may last longer and the cost is the same..
I bought 4 of those sets and so far after 2 months all of the rear ones work. Those have many different blinking modes so every time you want to turn it off , you have to keep pressing the button until it's off. No really big deal but kind of annoying.The front light ... well, 2 of them stopped working within first 5 minutes of being on. Other 2 lasted for about a month and just stopped working.Reason for 2 stars is that rear light actually performs well.
The front light worked for about 30 seconds. Then wouldn't stay on. After 2 minutes, it wouldn't work at all. Save your 3 bucks and change. You get what you pay for.
Ok first it took almost 3 months to get the item. But thats ok  i understand that somethings can happen that would delay the shipping but come on. I was so excited. I turned tested the head light and it barely lasted 1 minute until it died on me. Light wouldn't stay on after you press the button. After so many press it wouldn't even turn on. I would of given 1 star if it weren't for the fact they gave me three sets for the shipping inconvenience.
What the heck is up with this seller?I needed this 3 1/2 weeks ago. It gets darker sooner in Oct. What a waste of time and money. I need a bike light. I need one now. I will purchase one from a bricks and mortar shop in town. Amazon.... what are doing about this?
These lights are very bright and have many alternative flashing modes. Will be easy to attach to the bike. product is lightweight and inexpensive but will do the job.
Actually I bought it from ebay for 6 bucks. The mount broke in the first ride which was OK because I have super glue. But the 3 out of 5 leds died after 2nd ride. Now all leds died. Spend a few more bucks for the Bell headlight. Get rid of this junk.Update, I received a used replacement from the seller. There're 2 major problems:1. When you bike bumps, the light is very easy to get turned off.2.
If you're a mountain cyclist, I don't recommend it.For the price, the product is great. it comes with all AAA cells needed.The product itself is very fragile, my unite arrived with a broken handler, but, within 10 days I received a replacement. My rides are on mostly flat strands, not too much adventure, so, it works for me.
