What is the brightest, most powerful safety light that can be CLIPPED to a pannier? The pannier I own has a small tab on it that might accommodate it.

I would prefer buying a strobe light but I'm considering other types as well.
IF POSSIBLE, I'D LIKE TO GET ONE THAT CAN BE SEEN BY MOTORISTS DURING THE DAY!

Does anyone have suggestions? Feel free to PM me.
