Brightside Front and Rear 3 in 1, Multi Function Be Seen Light for Bike Helmets. 43 Hour Runtime. Fits Most Helmets. Bright and Lightweight. Waterproof and Rechargeable Helmet Light.

Brilliant light this. Long lasting and very bright. It's brilliant on the MTB. Highly recommend.

Second purchase now as they are very bright with various lighting options. Bought for me now after seeing my son use his. Fits well, front and back lights all in one. Great for helmet or bike.Happy with purchase.

Ok so, first my use scenario: I commute to and fro school with my kids for school drop-offs and pick-ups, that means its day light hours most time of the year. Most of the commute is on cycle paths with the few roads in between having sparse traffic but a couple of tricky junctions with cars parked on the side walks. I needed a helmet light as my seat-post is obscured by either a child seat or a tag-along so that blocks any rear light positioned lower. When my elder one is not being towed he might be in front of me which brings up multiple considerations for a handle-bar front light (being obsured, blinding when my child looks back). So I needed a nice strong 'day-time see-me' helmet light that can be seen over my kid and parked cars near junctions.The seven modes available come with various brightness/ lumens. The stronger of the two flash (front and rear) modes is 30 lumens at the front and 30 at the back. I found the back light to be really good at this setting but the front flash rather weak. On a cloudy morning we did not find the 30 lumen front flash attention grabbing beyond a couple of car lengths, and almost invisible when it got sunny.Now, there is a full 100 lumen front flash mode available but that comes with a 15 lumen constant back light, so if I set it at that the back is no longer attention grabbing enough. unfortunately a mode with the full 100 lumen flash upfront and 30 lumen flash at the back is not available. I would guess a 5 hour up-time would be possible with such a mode within the exiting product specs.That said, this is still a very good light, perhaps the best helmet light in the 30 quid price range out there for urban commuting. Compared to my cheap seat stay rear light bought off ebay the rear flasher is much better. My advise to people looking for an attention-grabber when the sun is bright and/or low is to spend more and go for something with more lumens.As others have pointed out, build is solid, battery backup time is good (no signs of it getting weaker after 5 school runs), easy to install though I would have preferred the holding bracket were flatter as none of our helmets are round like a handlebar, this means we find ourselves re-adjusting the tilt every so often.Also note the 43 hours marketing time is only for the weaker flashing mode. There is a nice table, with front and rear lumens and associated battery time present in booklet that should be reproduced in the listing.

Very well made light and attachments.Front and Rear light in one.Choose between front only, rear only or both.Flashing or constant options in all settings plus more.All the fittings you could need for attaching to helmet or bike.Quick charging . Very bright !!!Great value for high quality.Very pleased.

I ride an electric unicycle (EUC) which has good front and rear lights but, of course, they are quite low down. I wanted something I could mount on the top of my helmet to make sure I was visible to cars etc. This is super flexible to install. I used the included rubber figure-of-eight strap through the air vents on the centre top of my full face helmet (a Kali Invader) and it's very tight and secure.I've caught it on a few tree branches and it's never shifted.The light is surprisingly bright so when riding down dark trails or footpaths, I was pleased by how much it illuminates the direction I'm looking. Given that the EUC lights only point the way I'm going (as would a bike), this is useful for looking around. The button on the top is easy to find without looking if you need to turn it on or off while wearing it, and it's a simple hold to turn on/off and press to toggle flashing or solid.Finally, the charging port is well protected to ensure the whole thing stays waterproof but accessible enough to make charging easy without having to remove the light from the holder. Sometimes I don't even take it off my helmet! Only criticism is that it's micro-USB instead of USB-C but it comes with a cable anyway and that's more of a personal preference as I've mostly migrated to USB-C.

Negative: Not very bright front light. I was disappointed tgmhe front light was so dim. I was hoping to use for night MTB on trails. And wanted bright narrow beam. This is dim wide beam.Positive: great mounts, easy clip on to helmet or bar. good safety light for roads or cycle paths. Lots of light modes. Easy charge. Waterproof. Small light.I often take it as back up light for dog walks now. Is small and easy in pocket.

Had some very expensive lights for MTB over the years mainly Hope lights this light honestly holds upWell in comparison. I’m incredibly surprised how good this light is. it’s bright, it strobes well and can be seen from a good distance this has a great build quality for the price I highly recommend this light battery seems to last for a god few hours as well.

This feels like a quality item which is what I look for in safety equipment.The instructions are easy to follow (I'm female so I do read them) and the light charged up very quickly.Because the top bar of my helmet is very wide I had to use both of the rubber straps to fit it, but it does come supplied with tie wraps so I could have used those instead.Love that I can use it on my handlebars as a front light or on the frame at the back as a back light.Can't really assess battery life yet but I've been using it in poorish conditions and I am still alive so I think other road users can see me.Will definitely be recommending to family and friends that cycle and I want to stay alive.
