User questions & answers

Question:	Does this light act as a reflector when not on

Question:	does this tail light have external battery pack

Question:	Can i buy the silicone mounting strap for taillight, i lost my
Answer:	Yes I believe you could make one work. Good luck
Question:	Can you mount this on the seat stay? The seat is lowered all the way on my bike
Answer:	Not seeing exactly what you're trying to do, my guess would be yes. One option is to mount them on the top rail on the frame that goes down on an angle to the rear axle area since they do pivot/rotate to meet that angle and aim at traffic, etc. behind you. The rubber snap loops to adjust to that size of tubing on the frame.

Question:	Where can you get replacement straps
Answer:	Doubtful. It doesn't cover all of my mountain bile.

Answer:	Having never been near a beach, I have no real idea how big a beach towel is. I am confident a large bath towel would fit inside fine, but I cannot say for sure about a “beach” towel.
Question:	what is the output of these lights in lumens
Answer:	In my opinion, only the very smallest laptop would fit inside the bag; at an angle. Something like a large tablet would fit fine.
Question:	how long does the charge last
Answer:	The shoulder strap is for using the bag like a backpack....I threw mine out because I only leave the bag on the bike.

User questions & answers

Question:	venden el strap braket por separado ? Me robaron bi bicicleta pero tengo la flash light
Answer:	The blue light is brighter than the red light. Also drunk drivers tend to go towards red flashing lights that is why you see police, fire and ambulances start putting blue lights on the rear of their vehicles.
Question:	Does anybody know the actual Weight including the strap
Answer:	You could, I guess. But I think that would screw up the brakelight function. The sensor is best detecting linear acceleration/deceleration. I think your head movements would be tripping the brakelight all the time. It was charging, so I played with it just now. It would totally be continually tripping the brakelight if worn on the helmet.
Question:	My mount broke first ride, is there a replacement mount for this
Answer:	Might need some tape... I would buy two... One for each side... They work great thoo..
Question:	what is the advantage of using a blue flashing light over a red one
Answer:	It mounts to the seat stay/between the two rids that run parallel to the bike. . FYI, of the 2 I purchased, 1 failed in a few weeks. No warranty.

User questions & answers

Question:	Is this taillight suit for a kid's bycile? I mean I'm not sure whether the fastening fit the smaller frame tube for a children's bike
Answer:	Hello EMJ, these goggles also have black colors. You can search B01C8CFT8K on Amazon. This item is one size fits most. It might not fit a big nose or a high nose bridge. Hope this helps.
Question:	How is the visibility in daylight
Answer:	The anti-fog was good for the first couple of weeks. It's not reasonable to expect that you will never touch the inside of lens, or that the inside will not need cleaning. These googles are being worn in a pool after all. Evidently, if you try to clean fingerprints off even with plain water and a soft optic cloth, the anti fog treatment disappears, and the goggles will forever fog badly and quickly. I handled these googles gently and carefully. They leak also.
Question:	Is the list price for one single taillight or a pair of lights
Answer:	Hi Sarah, yes these goggles are leak-proof. They can effectively keep the water out yet won't create too much pressure to make your eyes uncomfortable.
Question:	Tempting price. What about the quality
Answer:	Same. These reviews are clearly paid or done by bots. The goggles are totally worthless for actual swimming... lanes are super dark and underwater is very blurry. Never used swim goggles before that had this effect. Film is also very heavily tinted unlike what the pictures show.

User questions & answers

Question:	How do I return a defective light
Answer:	I don’t know how many lumens for sure but it is much brighter than anything else out there that I have bought recently. I use it on the road because it has exceptional visibility between the red and blue. The white can be a little blinding to others if riding in a group when on the high setting. I highly recommend this light if safety and visibility are your concerns. Simple non slip mounting and angle adjustability.
Question:	Does it stay secure enough? If you ride over a bump does it fall off
Answer:	Hi. Each lamp is packed in a plastic box. The weight is about 70 grams (including the box).
Question:	Why does my light keep turning off in the middle of my ride
Answer:	I have used them on the brightest red blue flash setting for up to two hours without running out of power. They are really great. They are the same as ones that cost more and are the same shape. I have both, these and more expensive ones that look the same.
Question:	How many lumens
Answer:	They are simply 12-volt lights. They were very easy to install on my 2004 LJ. You might have to cut and splice but even that should not be an issue. The connection plug worked just fine for me..

User questions & answers

Question:	Good morning I put new batteries in my unit and it doesn't work what do you think the problem is
Answer:	Please make sure that you are using Duracell or Energizer alkaline batteries. High quality batteries ensure that they provide steady voltage output, so the light will be powered up at sufficient voltage. If the light remains not working, please feel free to contact us.
Question:	does it come with a mounting bracket? if so Pictures
Answer:	The light has no mounting bracket. If you have access to a band saw, drill press and bench grinder you can easily make one. But otherwise I'd pass on this light.
Question:	Would be exactly what i was looking for if it had a built in battery and usb charging. :-/ light + reflector + rack mount
Answer:	We encourage you try this BKS-G4 out with your own AAA type recharageable battery and stay tuned with us.
Question:	can the attach bolts be replaced with longer ones to fit my Tubus rack
Answer:	There is no type of mounting bracket or bolts included with the light. It's just a light.

User questions & answers

Question:	My secure hooks broke, how do I get new ones
Answer:	You probably keep losing the clip on style lights. If so I know your pain. I put the SB rear light on my mountain bike over a month ago and it hasn't moved a bit. Totally different mount style. You should definitely be fine on a road bike. Extremely bright light from the rear, wished it was a little more visible from the sides. Easily worth a try
Question:	Is a clear lens available for this light
Answer:	Best to turn on and discharge all the way out of the box, then fully charge after
Question:	Is there a video showing the different settings? Can someone post one
Answer:	99% of road bikes here are equipped with a small bag for tubes, tools and air cartridges. They usually have a strap for attaching this light. That’s how I have mine.
Question:	I've purchased 4 different back lights for my road bike and all of them have fallen off if I hit a bump, etc... Will this light stay affixed
Answer:	The light itself without the mount is 1.37 in wide. Max height is 2.78 in. Max front to back is 1.496. The mount will offset the light from the mounting point by about 0.75 in which means that the light will extend from the mounting point by about 2.25 inches depending on angle and how tightly you strap it. I think the 3x8x2 they refer to is the size of the box it is packaged in.

User questions & answers

Question:	How is it rated against water penatration
Answer:	I have two of these and they both show >270° on the unit itself. In addition to the main, rear-facing lens, there is a protruding side panel on each side that fits between the notches of the fastening band. These would be the source of any visible flashing light beyond the 180° arc seen from a rear viewpoint. However, given the rider's legs, anyone in an oncoming position from an angle beyond 200° would not see much in the way of a warning flash (maybe just a diffuse red glow from the whole contraption), hence, the need for a flashing white headlight.
Question:	I don't see the charging port. where is it? can you easily get the usb plug into to charge the light, without removing the light from the bicycle
Answer:	Greetings. Great product at $19.99+tax. I use them daily. 5-7 AM. I charge them every 3 to 4 days. But it has not ran out on me after 3-4 days for 2 hours per day.
Question:	How good is the side visibility of this light
Answer:	This rechargeable unite is very bright $ 16.99 with 5 patron lights and Volcano Eye lights are $ 24.99 comes with 7 lights patron , There is $8 difference and 2 lights patron short I believe that $16.99 is very sweet more than $24.99
Question:	Why does the angle that is labeled >270° in the graphic on the side of the unit measure
Answer:	Yes you can mount the light any where .
