I had one of these on my bike for a while, it is quite bright and does get attention.

They will still rear end you even if you had a million candle power rear light as they have to be looking where they are going to spot you! My mate was rear ended on his ZZR1400 just before Christmas in daylight while he was travelling at 40 mph in moving traffic. He was shunted forward just missing the cars in front. £3000 worth of damage but he survived somehow.
I don't know if it's worth the extra expense and work to put on brighter rear lights.
