User questions & answers

Question:	Does this light act as a reflector when not on
Answer:	No it doesn’t. I just road by bike this morning and the bright flasher mode is terrific
Question:	does this tail light have external battery pack
Answer:	No, it comes with a charger for each of the two lights. This is a great product and well made. I had a tail light by another company and it was cheaply made and didn’t hold the charge. I’m much happier with the Asher product.
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:	How long do the batteries last
Answer:	Yes, the smart brake light works normally during charging!
Question:	does this use AA batteries or AAA
Answer:	This light does not work as a brake light consistently mounted to the seat post. It turns itself completely off in daylight except when left on steady, then it eats up the battery in fewer than 10 hours. I would not expect it to work any better mounted on a helmet.

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:	How long does it take to fully charge the battery
Answer:	With an imperfect ruler--1/2 inch wide; 3 inches long 5 inches if you include the hook and the base of the light.
Question:	Can this slide onto a saddle bag without using the rubber mounting band? In other words, does it have something similar to a belt clip
Answer:	They will work on anything you can mount it on. Mounts with a clip or a strap.
Question:	Could these be mounted on seat stays
Answer:	About 45-50 hours, maybe more. I run my lights on constant mode 45 minutes daily for my morning bicycle commute, change batteries about every 10-12 weeks (voltage usually about 1.22 per alkaline battery or so when I change them. The lights dim at about 1.25 volts.) The batteries are very easy to change, easy to open the light and remove and replace, takes about 10 seconds and no tools. I use 4 tail lights on my saddlebags, cars avoid me. Be safe, be highly visible, use at least two lights. I bought other lights, but I prefer these and use them exclusively now for my tail lights.
Question:	How wide is the rubber strap
Answer:	AAA. All of these small lights that i have seen use AAAs. The battery life with LEDs is extended by using the blink setting as opposed to the constant on setting, but is pretty impressive either way. Unless you're planning on a bike trip across the Gobi Desert without spares, I wouldn't worry about the difference between AA and AAA.

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.

Answer:	I don't know why but mine was doing the same thing. At the time I was riding 2-3 hours on a ride and then again on the next day. On the second day my light would turn off during my ride. I would turn it on again and it would usually work the remainder of the ride. Then I started recharging my light after every ride and have not had the issue since. The time between charge for the light seems to have been optimistic.

User questions & answers

Question:	How do you know when it’s fully charged
Answer:	When you plug it in one of the ends will light up. When fully charged it will turn off. Charge only last 2-3 hrs
Question:	Is this rear light suitable for technical mountain biking and flying down bumpy gravel roads, or is it going to bounce out of the mount
Answer:	Since these lights are attached with strong adjustable plastic straps, they should hold secure on bumpy rides. They’re similar to the straps on my Thule bike rack.
Question:	How many lumens
Answer:	I don’t know but they are very bright and can be seen easily. Great lights!
Question:	Is there a warranty
Answer:	Didn't check. It is a great light.

User questions & answers

Question:	how long do I charge it for the first time out of the box
Answer:	Yes, the clip on the back will attach it to a backpack, etc. *Note of caution: I've had one come off a saddle bag before. Make sure the webbing/strap is "captured" by the notch at the end of the clip to prevent it bouncing up and slipping off your gear. The width of the webbing material you attach it to may be a factor. For reference, the "depth" of the clip from stop to notch (or, if you prefer, the width of webbing the clip will secure to) is just under 30mm, or about 1 1/8 inch. Hope this helps.
Question:	Is there a mount that will fit on the rear of a Trek road bike? The frame is not round but more oval
Answer:	The remote control does support to control two tail lights at the same time, but you need to pair yourself, you can contact our customer support team, and they will send you how to pair, the email has been attached in the final page of the user manual.
Question:	What are the real dimensions of this light, item description does not make sense
Answer:	Yes
Question:	Will it attach to a backpack or messenger bag
Answer:	Yes. The remote control is rechargeable. You can easily release the remote and take it home to charge it.
