I have a Cygolite Expilion 850 that I've been using on my helmet, paired with a generic MagicShine clone from Amazon with the diffuser lens on the bars, which I'm ready to replace. I like that the Expilion has an internal battery that can be replaced and that it's fairly cheap and made in the USA so I thought about getting another one but I've also thought about getting something that is more of a flood light. Anyway, I'm wondering if anyone out there has used two Explions together? Thoughts?
