I got the light from Amazon and the rear alert from AliExpress. The light has different modes and the light color is not off-white. The light has a problem that it doesn't charge, meaning to work, you have to connect a portable charger directly for it to work with you. As for the alert, there is nothing wrong with it, it works well, and I changed the remote battery. The prices are clear in the picture, I am selling both for 100.
