GiroRoc Loc 5 LED Rear Helmet Light(Return to Product Page)

I really like the idea of a light that is custom-made to fit my helmet, and it does indeed fit well, with no noticeable added weight or bulk. It is bright -- I worry that it might be too bright and thus annoying to drivers, but no one has honked at, yelled at, or thrown anything at me yet. Wish it had more options than steady & flash, and the charge does not last as long as the blinky I had been using previously. The biggest problem, and it is a big one, is that the light snaps on very loosely, and it is very easy to knock it off if you are adjusting the helmet's roc loc wheel. I've had it fall off a number of times--though always from me bumping it with my hand, never just from bumpy riding. I may zip-tie or even glue it if it falls off again.

This is a really good, simple solution for anyone with a Giro helmet using Roc Loc 5 retention. I use this on my Vanquish and it works perfectly. Button is easy to find, it doesn't inhibit access to the retention adjustment and it doesn't add a lot of weight or jostle around like a velcro'ed on clip light would. I honestly don't even realize it's there after I turn it on. It's bright, it mounts securely, and the USB port is easily accessible without removing it from the helmet.

If I had to come up with a negative... and I'd be really grasping to do so... be nice if it had a 3rd light mode with maybe a little more irregular pattern. But again, that's really a stretch to come up with something negative.

Light is very effective. Very visible in both modes and well positioned on helmet. Light would be effective on it's own. I use it in conjunction with a Nite Ryder rear light attached to rear bike rack. Drivers appreciate the effort and give me a wide berth at night. BUT there is a downside.

Clip on light's hold to Roc 5 system is pretty "iffy" It detaches very easily - especially when taking helmet on or off. I also lost mine once while riding. Solution: Use a small zip tie to secure the light to the Roc 5 suspension system.

You can never have enough lights on the road, if you ride on the streets or county roads occasionally like me. Especially nowadays, seems like we hear of accidents involved cyclist and cars just about every other day. I wasn't sure if this one last based on how it is mounted on the helmet, but after several rides, some very bumpy the light stay put! Ingenious!

It is bright enough for traffic to pay attention and solid enough so I don't have to worry about losing it. Good product.

Perfect fit on my Giro Eclipse helmet and my wife's Aesther helmet. Very clever design.

Bright enough easy to turn on change blink mode and off. Good battery life. These are so easy cuz no need to be moving lights around for 3 different bikes. Just take your helmet, genius!!

This is a nice light but it only truly fits the Roc Loc 5 that has the soft rubbery adjusting wheel. My Roc Loc 5 has the hard plastic adjusting wheel and I had to use two zip ties to tie it to it�s intended location. Just check your adjusting wheel on your Roc Loc.

I bought this light because it was compatible with my Giro Helmet. However, the first one I received proved to be defective and I had to return it for exchange. The replacement has worked well so far, but we'll see how it is over time.
