sylvania silverstars, the 9005 conversion....for the money its the best lighting upgrade you can do for an accord. to me the piaa's suck, nice and white and they just dont do much for actually seeing anything though...and those showoff bulbs are weak next to the silverstars.
my high beams are still stock bulbs, and my lowbeams(silverstars) throw nearly as far, though they are focused down so as to not blind anyone.
