STEEL MATE H2 Helmet Brake Light and Running Light for Motorcycle Safety Rechargeable LED Signal Light for Helmet (WITHOUT ECU)

Okay, I actually only have one light on the rear of my motorcycle, so I guess with would be properly declared as a "2nd" light (LOL). This item installs in minutes and works as advertised. Instructions are clear and there is a template to help center the device on your helmet. Adhesive holds the magnet on very securely and the magnet is super strong to hold the light on. I recommend cleaning the helmet area with alcohol to ensure strong adhesion. The light can be removed with some force without upsetting the magnet. I installed this in about 10 minutes and went out to test it at night with an observer. The observer stated every time I hit my brakes, the helmet light came on within a second or two. I did this several times going up the street and was told it worked each time. The light is very bright and can be seen at far distances. There are different colors/combinations (red, blue, orange, rainbow) to choose and various lighting patterns. You may want to check with your local ordinances on colors and some of the flashing patterns, since some of these can mimic emergency or police vehicles which may get you in trouble. The battery lasts a long time and there is an indicator that lights up the lights in a row to let you know the charge level when charging. Charging is via USB and the cord is provided. This unit will shut off to save the battery if no movement is sensed for a period of time. Overall, I think this is a nice safety device and it works very well. The unit is very sturdy and appears to be of very high quality all around. I recommend it.

This light is absolutely amazing. Large in size and very bright. All of the different settings are really fun. Magnet that holds it on is super strong.

This light works great. It has long battery life, they say 18 hours and based on my experience I believe it. The lights are very bright and quite noticeable even in the daylight. The unit is a little heavier than I expected, but you don't have to leave it on your helmet all the time if you don't want to use it during the day, it easily mounts and unmounts via a magnet. I have not had any problem with the adhesive not sticking, it sticks very well and the magnet has never worked loose. I also like that you can buy additional mounting plates, so if you have multiple helmets you don't need to buy a light for each one. You can just buy a base for each helmet and then swap the light between them. I would definitely recommend this light.

I bought this a few weeks ago to increase my visibility from the rear. Riders behind me report it isn't very visible during the day, particularly in bright sunlight, but at night it's very bright. Not long after I bought it, I got caught in a bad thunderstorm - torrential downpour, lightning, thunder, wind. I noticed that cars behind me tended to keep their distance, and my husband, who was riding behind me at one point, said the light was very bright in the half-twilight. Also, in the downpour, the device proved it is waterproof! Though I tend to turn it on before I put the helmet on, if needed I can reach the on/off button with my right hand.Edit/Update:I got my helmet out of storage for spring riding and find that the adhesive is breaking down and not holding the light firmly to the helmet any more. I'm going to do what other reviewers have suggested and reinforce it with a command strip.

The media could not be loaded. I would recommend this product to anyone that wants to be seen safely on the road at night or even at dust or Dawn. This thing is extremely bright and could be seen for quite a distance before you get to it it's very small but very robust. Once applied to the proper place on your helmet it flows with the streamline of the helmet's quality and lines it's easy to install and makes writing at night a whole lot safer.I do however wish there was a way to set the sensitivity of the unit, as engine braking does absolutely nothing, and the unit will only illuminate once hitting the brakes. But because of the scrolling effect of the lights it does make you more visible at night.
