LucidBrake Bicycle Brake Light

This is one of my favorite products.Selectable flashing or solid light for illumination, and the added bonus of the stoplight activated by physically stopping the bicycle (or yourself). The lighting and stoplight function both work very well.Sturdy velcro fastening for mounting, but could also be (carefully) drilled for permanent mounting as well. I use rechargeable batteries, and they work great.

extremely poor design and fragile inertial sensorpro 1: lights are bright and circuitry is intelligently designedpro 2: entire circuitry is coated in urethane or similar sealant appearing to offer a lot of water resistancecon 1.no good way to mount it. the manufacturer says: "The attachment is 'Dual-Lock' and it is the same stuff that they use to put siding up on buildings in Minnesota. It is rugged and strong and will stand up to weather. It is also rated by the manufacturer to use 1000 times without a failure"the idea here is if it will hold up siding on a building in minnesota, then it's a good idea to use a 1" square piece of it to hold a heavy part on your your bicycle. this shows a very poor understanding of the application. first even if this dual lock type 'velcro' works the adhesive does not. i stuck it on a cleaned surface on my motorcycle helmet and it fell off almost immediately. it was not the dual lock 'velcro' that failed but the adhesivealso, the dual lock 'velcro' only works well on a perfectly flat application. if your surface is curved it will limit engagement of the dual lock 'velcro'con 2. fragile. the moment mine fell to the floor after the adhesive failed the inertial sensor went kaput and that was the end of the unitcon 3. price. the price would be ok if it had a well designed and solid mounting system and didn't immediately break from a minor fall, but no one wants to spend $75 on a piece of junk, which is what it is given cons 1 and 2 above

This is a product I would like to give five stars to, but just can't.First, this has issues as to where you can attach the light. The velcro is high grade and that's not the problem. The problem is the sticky surface where you can place the velcro where the light will attach. I primarily got this to attach to a bicycle carriage for toddlers. The sticky surface of the velcro would not attach to the outside fabric. I then tried to attach to the back of my helmet - not my first choice. I found even that difficult. The only spot where the velcro would stay secure was a spot where a sticker was already applied to the back of the helmet. At this price range I'd like to be able to attach this light to almost any surface I want.More important than the limitations of where to attach the light is the issue of how it functions. The light has four functions depending on how the light is positioned. I'm not a fan of that at all. The primary function that sets this light apart from others is the alleged ability to sense movement and brightening up when you brake like you have when driving a car. That's the upright position with logo legible from. When I first got the light I tried walking around with it and it seemed to work. When I stopped walking it would brighten. I though, okay, this is going to work.When I tested it on the road with a bike, it didn't work. It worked sporadically. I also discovered another reason I didn't want the light on my helmet - the weight of the light made my helmet tilt down in the back making it even less likely those behind me could see the light. It's not a heavy light, but it was enough to be an inconvenience.At this price point the major function of this light is movement sensing. In my tests I found it didn't work nearly often enough. If this light were priced lower along lights without this function then this would be far less of an issue. Unfortunately, my advice to the makers of this light is to go back to the drawing boards and fix this or lower the price so that the sporadic functionality won't matter to buyers.

UpdateI have a new and improved bike with a new and improved seat.Since this light requires a flat surface to mount it on i am up a creek as there is nowhere i can mount the light upon bike where it will be visible.I had to do some jury rigging on old bike, but on new bike nothing working.Too bad because even though it is way overpriced and ugly it WORKS!==========.I was underwhelmed when this $75 light arrived (and for $75 it should have included good batteries). Looks really cheap and basic in designIf i had seen this in a store i would never have paid more than $25 for it.That said, if you have the funds it is a very nice and useful light.I see others have found uses for it apart from bicycling.I am using it as intended on my bicycle.The light is 3" across and is very lightweight, which i hope doesn't translate into poor durability down the road.The light is wireless, which is nice.When flashing it looks like one of those restaurant pagers, which means it is bright and noticeable, which i like.As a note to the manufacturer who provided this to me in exchange for an honest review, the packaging needs some finessing to draw in the kind of people who are willing and able to pay $75 for a bicycle light.Note: For those who think amazon vine provides items 'free' to reviewers, please note that we have to pay income taxes on the items we review (which means i definitely am paying for what i receive based on my tax bracket) and most of us actually do spend time using and evaluating the items in hopes of helping other buyers make informed decisions.
