Do they stay light 24/7?

no they on blink are on when there is a tire movement. like hitting a bump. what I do to extend battery life is I remove them in day light and put them back on just before dawn or night fall I went a full year before replacing batteries. or lamps I just reordered for additional bike purchases I liked them and they did a great job at night.

Only when your driving.... Only good for about a month but it's awesome! Definitely turns heads

Only when moving, there's a spring in it that completes the curcut when it vibrates and touches the metal lead. Very brittle though.

I don't believe so since they don't give off heat. And we don't keep them on 24/7 in any case. Hope this helps!

Yes they flicker, but they can be set to just stay a constant light as well. You can adjust the flicker too. Hope this helps!

Yes, they should glow. I've used similar ones before, and all the glow-in-the-dark stuff tends to glow with a blacklight, which is nice, so they'll stay lit as long as you like. :)

Yes, they are fantastic! Generally they are still on when I wake in the morning but it depends on how much sunlight they get during the day to recharge the batteries. I would recommend them to all.

They will survive the winter weather ok, however, due to the short, cloudy days they will only light up 2-3 hours each night. When the sun is out many more hours per day during the summer, they will light up 6-9 hours each night.

I have five of them at my place. They go on when the sun sets with a low level of illumination, but go bright whenever anything passes within their sphere of activation, and then the light stays on for about two minutes. The duration is not adjustable as far as i know.They do what is expected of them.

No, but it will stress out the fish or animals to have the light on 24/7. They need a cycle of light and dark so I recommend getting a timer.

No, and these also cannot be left on more than 20 hours consecutively, nor do they have automatic on/off triggered by natural sunlight. I have to replace mine now, less than a year after acquiring them. Ugh!

I just got my light about 2 months ago, and so far, if it is charged properly during the day then yes, it does stay on the whole night, emitting a dim light. When there is motion it gets temporarily brighter.

We've had ours for a few months, and they're still working just fine with no signs of dimming. They don't come on at all during the daytime, and when triggered, they only come on for about 5-10 seconds. I think this helps prolong the battery life.

I have had for half a year. I don't leave the light on very long so I can't truthfully answer.Love them,though!

No but you can dim them down or put them on full blast. I have mine hooked up to a timer so that when I enter the house at night I am not entering in total blackness.

Yes. If your light switch is on, they respond to motion both day and night. I had my electrician tweak them to stay on longer because they were set to turn off after 5 minutes of no motion.

Nothing, you have to remember there are not that many hours of sunlight at this time of the year. The batteries are only getting charged enough to give a short time of light at night. Mine are in full sun all day too and I maybe get a hour of light. In the summer they get so many more hours of light and it first gets dark at 8:oo or 9:00 central time, then they seem to stay lit almost all night. If you want them to stay lit longer for a few nights, remove the battery and give it a full charge in a battery charger that you plug in to an electrical outlet. I hope this helps.

Yes, they only go on when the light is quite dim. It doesn't have to be totally dark. I was skeptical at first, these are surprisingly useful. I just ordered a second set for a different location in our house.

Yes and no. There is a switch to turn them on, but they won't come on in the day time, only at night. But you can turn them off so they don't come on at night.
