They are very simple to install, they "seem" to be very sturdy. I know OEM turn signals wouldn't survive a crash most likely but these definitely look like they would. The brightness of the LED's is very good. No problems for people to see them. My only objection is their method of connecting. The connection could be a failure point depending on how you do it, would have been better to just include oem connector on end of wire.THEY LOOK GREAT THOUGH ON THE BIKE!
