I know the OP already found a replacement, so am including the below just as an FYI for anyone else looking in the same category.... I`ve seen Streamlight call their microstream a keychain light, and it does indeed come with a ring mount on the pocket clip that you could easily attach it to a key ring. But, seems a little large for a ring light for my taste. However, it is a quality light and has an all metal body, so go ahead and fall on it all you like, you`re not going to break it. It is a little more than your price target about $15 seems the average. here is one place it is available.
