Mengshen Smart Bike Tail Light Rechargeable, Remote Control Anti-theft Bicycle Alarm Horn with Turn Signals Brake Rear Light Auto ON/OFF Waterproof for Cycling Safety

I drive and ride a motorbike. While I know hand signals I do prefer indicating my upcoming direction changes. I didn’t think I could get this on a pedal cycle. But I can.It’s bright and it’s obvious. It even makes sounds to let pedestrians know I am turning. The horn function is loud and makes people stop and look - exactly what you need if something is about to be a danger for either themselves or me.The anti-theft alarm is exceptionally loud and very welcome even when my bike is locked. People would not know that the rear light is an anti-theft alarm which is great. It’s caught me by surprise once or twice.The one drawback (and this is not unique to this device) is that there is no thought given to front facing indicators. I can get individual indicators for the front but that means an additional item on the handlebars. The first company to do an all-in-one indicator and rear light package will corner the market, in my opinion

The unit itself is absolutely brilliant. Indicators work great, rear light with integral brake light is fabulous, and the horn is definitely loud enough. The alarm can be armed and de-armed easily and works well, so all in all everything is fab so why the 3 star review? Very simple - the fixing clip that fixes onto the bike which this unit then clips in and out of is badly designed. Once clipped in it is impossible to remove again without inserting a small screwdriver to open the snap clip element. As the unit would ideally be removed every time you park up or leave the cycle for a long period then this is a major flaw, unless of course you are happy to leave on the bike in alarm mode which isn't always the best choice. I am worried about breaking the clip and so am a bit reluctant to use it, which effectively renders the whole unit useless until a new fixing method is sorted out .... or, you leave the unit on the bike and pray that no-one else tries to steal it which feels like a totally unnecessary risk. If left on the bike all the time I'm not sure how to charge it without an extension lead in the garage which feels a bit over the top really.Additional Note : I just tried to open the handlebar control unit to make sure I could get a replacement battery in (when it would eventually be needed), and the tiny Phillips screws feel as though they have been machine tightened. They are almost impossible to remove without damaging the screw heads. I did manage it eventually but one of the screws now needs replacing. It's a silly little thing to have to moan about, but if the battery compartment can't be opened once the battery runs out, then the whole unit becomes redundant.If the brittle clip can be resolved along with the battery compartment cover, then this is an award winning product!!

As with all too many poor quality plastics, thermal testing was neglected a little. First sign of cold weather and the control mount shattered.If replacement cannot be obtained light will be a wate of money.

No se como se coloca bien la luz, la he puesto pero esta un poco floja, no hay vídeos de como se coloca, gracias
