Anything that aids in illuminating your presence to catch the notice of the motoring tards is a good thing. There is no such thing as overkill when it comes to being noticed.

I have a rather unusual headlight, it's a 61-bulb LED, with 1 hi-output LED in the end (flashlight-style), and a 4x15 grid in the side of the thing, pretty bright and noticeable. It's aimed so the grid shines forward. Puts out good glow, and is easy to see....

So I thought; it was bright enough for illuminate the driver's use of his cell phone as he narrowly missed me during my commute home the other evening! He didn't even notice, not even when I cussed him out!
