HAHAKEE Bike Tail Light, USB Rechargeable Bicycle Turn Signal with Wireless Remote Control, 500 Lumen Red & Yellow LED Road Safety Indicator Cycling Rear Flashing Lights

This has definitely been one of the coolest bike accessories that I've owned. Makes riding at night feel MUCH safer. Daytime is of slightly less use; on a sunny day, the turn signals are a little too small and not quite bright enough to be able to tell at a glance which direction they are pointing. Love it for night time use, though. I only wish there was a solid rear running light plus a brake/stopping signal. Not a huge deal, though, since I already had a solid read LED so I use them both for this purpose. =)

I feel bad about the biking community not being respected by cars.This future ocean plastic is SO BADLY DESIGNED!Major Failure: in the bright sunlight, user will not/ can not determine WHICH setting said signal may be.Example: Photo (left turn signal set((supposedly blinking))

This is indeed a very bright light. That is by all means the best part of it.When I received it and there is a second battery I thought wow how nice is that! I soon found out why. After about five days the remote battery was dead. I put in the new battery and used it twice and then left for about a week and when I came back the battery was once again dead.Here's the deal. The remote gets a single from the light indicating what is happening i.e. light on, light flashing, or a turning single activated. This is nice that you know your tree and singles are on but of course it only works when it is not bright daylight out. For me I ride only during the day mostly so the bright light flashing is what I wanted and this fits the bill. My animated hand singles are plenty good enough or turns. At night or evening, the turning signals would come in handy and the remote would work just fine for that.Since there is no way to turn on the light without the remote, my method is to hold the battery in while activating the light and then removing the battery and putting it in a baggie until next time. I just turn the light off to stop the flashing after my ride.It would be very nice if they added a switch to the remote to deactivate it when not being used.

It stopped working 2 weeks after I got it idk what happened to it but was just on my bike and went out and stopped working

As the Mother of a teenage boy who literally rides his bike everywhere these lights have given me a great deal of peace of mind. The lights are very bright! They are so bright that they are visible even in daylight, which was a huge concern of mine. The controls are able to be mounted just about anywhere on the handlebars or frame so that they are easily reached by the rider and are easy to understand and use. I love that the light is USB rechargeable so I don't have to be worried about having batteries on hand to keep him safe. And he thinks that the turn signals are "cool" so I don't have to worry about whether or not he is actually using them when he is out on his bike.

Almost have been run over by cars with drivers not understanding an extended arm left turn signal so I bought a light which has what I needed.I did not mount in the customary position which would have been simple but rather at the end of a rear carrier so now I have 2 rear lights only this 1 also has a turn signal. The bluetooth worked perfectly & it is a bonus that the light is rechargeable.

Update: I want to start off saying that HAHAKEE-LIFE customers service is great I explain to them what happen to my bike light. They gave me a promotion code all I had to pay on amazon was 30 cents. BUT PLEASE NOTE THAT THIS LIGHT IS NOT WATER POOF OR WATER RESISTANT. SO WITH THAT BEING SAID BE CAUTIOUS USING THIS PRODUCT IN THE RAIN. MAYBE THE FIRST LIGHT WAS 1 OUT OF THE BAD BUNCH. I WILL CHANGE MY RATING BEING THAT THE CUSTOMER WAS GREAT WITH ME.Used the light in the rain two days now it don’t work because water got inside. They really sweet and market it’s water resistant

I was pleasantly surprised with overall quality of the build! It did NOT feel like a cheap, plasticy, piece of equipment. The remote control worked as advertised with Right & Left indicator and blinking hazard light. Unfortunately I only got a chance to use it for a few hours. One the first day I used it, it started raining during my bike ride. When I got home the light would not go off when I pressed the power button. Once it did finally go off I could not get it to turn back on. So I put it on the charger thinking it was a battery issue. After a full charge, I was able to turn the light off/on but the remote control no longer controlled ANY of the lights. I tried changing batteries in the remote, holding the main button for it to resync, but nothing worked. Very disappointed!

I have tried at least half a dozen different turn signals on my e-scooter and e-bike. This ranks as the best so far. It is the brightest and the easiest to mount of any I have tried. In other reviews here, I see buyers asking if these units can be used front and rear. A definite YES, and you don't need to open them up and re-wire them (if that is even possible!) Just mount the front unit upside down (POWER SWITCH UNDERNEATH), and it will flash the same direction as the rear unit. To sync them, I first push the power buttons until the red light comes on solid. Then I press the remote control's center button as many times as needed to set the red light to my preference - solid on, flashing or off. That process connects the remote wirelessly to both lights, by the way. Now the direction signals of both units will respond. At the end of the ride, I found a simple way to be sure the power is switched off completely on both lights. DON'T USE THE REMOTE to do this next step. Use the power button ON EACH LIGHT to cycle it through SOLID RED, FLASHING RED and OFF. That shuts each light off completely so that no power is wasted. How do you mount a rear turn signal? On my Apollo Explore I cut a tiny "post" 1 1/4" tall from a mini plunger wooden handle, drilled a hole in the bottom and fastened it to the rear fender with a single wood screw coming up from below. I glued a black crutch tip over the "knob" to give it a finished look. I was frustrate with the remote control, because the green buttons are mushy and in sunlight you can't see the flash of the internal LEDs. I removed all 8 screws from the remote and took out the green rubber button pad and its round plastic back support. After cutting away the black plastic strip across the front of the remote, I can now see the LEDs and press the actual buttons. I am very happy with the result.

The turning lights and flash light work fine, the only problem is with the remote in the daylight you cannot se the light flashing in the remote. The wife and I bike together so we have to tell each other if the signal light is on or off, because we cannot tell by the remote.

The remote is almost useless, you never know if it actually turned the signal on or off because sometimes you have to press it a few times. The light on the remote is way too dim so that doesn't help, its more of a distraction as you have to keep checking if its on or off. Now its just an expensive flashing red light, which dies fairly quickly.

Put onto Mountain Bike, good use when teaveling around the City

Like it veey bright, could use improvement for battery duration, it lasts aprox 3 hours, would appreciate longer
