Do these flash - or are they constant lit?

They are constantly lit. Just to warn you, the part that clips in your hair is a bit bulky.

The flash light stays steadily lit, and does not strobe. It's quite convenient.

They are. I have mine outside and they do fine. Not very bright as the moment though, but I'm in Oregon where it gets dark so early. They were a bit brighter when I first got them, earlier in the year, and I expect them to do very well this summer.

I have 5 of these lights, I sent one back because it just flashed constantly. But the remaining 5 lights work perfectly. Important to leave light in solid sunlight in recharge mode for at least 2 days before activating.

Yes they are static lights, so they just turn on ad a nice and bright, the whole time. I'd test to see how it looks on video to see if you like the way it looks.

Yes. These only trigger the flashes firing, it doesn't control the amount of power that each flash uses.

So far I've used them to flash on at least 15 traffic crashes, some of which last for MANY hours. I can't say for certain, as I haven't tried it, but mine have worked over various incidents for at least 50 non-consecutive hours. They're quite awesome and quite bright.

But mine have seemed to work fine. I haven't put that many hours on them. I purchased 3 and they all worked. Especially combined with other types of lighting.

I think they do flicker like real ones. I really like mine. Nice not to have to worry about flame. I am very happy with mine.

I couldn't tell you, as all of mine have burned out. Cheap Chinese junk. Beware. They run for a few months, then start flashing like a strobe.

Lights do come on but they do not keep rhythm to the music. They will flash though. Sometimes slowly, sometimes fast.

No. They stay on all the time, but use very little energy. Very soft light, very pleasant.

Only if you hook them up to some kind of flasher circuit. otherwise they stay on.

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!

They are instant on I believe ( I'm using a dimmer ) , I wouldn't recommend buying these, I have replaced them few times since they burn so fast

I just got them this year, nothing burned out yet. I wouldn't think so as each light is kind of on its own cord.
