The cons: No matter how much I cleaned the surface, they will not stick, I drilled a tiny hole at the end of the strip and added a tiny screw, and used hot glue at the end with the connection cables. The pattern is not changeable but it does attract attention, it may not be legal in some places, just in case I added a on-off hidden switch. I would recommend this lights.

These lights do not work as they claim they only stay red when I hit the brake I got them just because they were supposed to track as we all know that riding on 2 wheels we need all we can to get one's eyes open when we are coming to a stop

Look nice, but no way to control the patterns. If you use multiple strips, they go out of pattern sync quickly.

These actually cycle through a bunch of patterns. Not just a side to side scanner like a expected. Only a 4 star for that reason. Ill keep them because they still look cool and super bright.

I never read the fine print stating they were the "Night Rider" flashing lights so you can imagine my surprise when I got them hooked up!WOW are they bright and pure entertainment!!! I now have to go back and wire them to a separate switch but they are definitely staying on my bike!Even the blind will be able to see me now!!! Love them.

Took almost a month to get them. I guess that's good coming from China. Also, like other people, these lights oscillate and you can't get them to stop. I think the header description is misleading. I was wanting to use these lights as accent lights in my Jeep, not a disco tech! Maybe I can find some dumb kid to buy them for $20 bucks.

Not a big fan of rapid strobe patterns. Only a few patterns resemble the knight rider patterns. The LEDs are bright and for the price it's a good product.
