Unfortunately, the way these are designed you cannot stand the bike up with them attached without them turning themselves on. The click/depress to turn them on/off will get triggered every time you stand up the bike, and run the battery out. Not to mention just having them red light glowing underneath the bike persistently. So you have to unscrew them off every time you want to stand the bike up, and then screw them back in the you want to use it. It's a rather annoying inconvenience, and seems like something that could have easily been designed to account for with an extended outer ring, but here we are.

Works great!

I waited months for these light because they were on back order. And I am glad that I waited, and didn’t purchased a knock off version. These lights are a great addition to my GSD R14. They allow for added visibility in the rear of the bike which is essential. They are very well made. They are powered by super bright LED’s that perform a few different flashing modes. I pair them with a set of the amber lights for the side of my clubhouse for added side visibility as well. So, these along with the brake light, has me fully covered. I highly recommend these lights.
