Lights

Does anyone have ANY idea how much 500w of blinding rear light crap pisses off drivers, especially in the rain, and how totally unnecessary and counter productive it is?
I think about that sometimes with a cherrybomb rear light, but at the end of the day I only have one light and with my life at stake I'm probably going to err on the high side - right? Though I don't know how the cherrybomb compares to the rear lights discussed here, it is rather dazzling.
