Need some help choosing some drop-in modules

[Paul]

I'm going to make a bicycle light setup with two red and one white led. They're all going to run from the same battery source and preferably have the same modes (not 100% required). After some browsing around at DX I've come up with these two modules: Red and white. The user review of the white one doesn't look too promising but it's the best I could find. Would those two drop-ins be good? Anybody got some other ideas?
