You're thinking of a capacitor, perhaps.
I thought a bridge rectifier was made for converting AC to DC (albeit not quite perfectly)...basically converting the sine wave to, gah, what's it called...the voltage would be converted to all-positive, but with dropping-to-zero pulsing, rather than dropping way down into the negative for half the cycle. It would dim, but it wouldn't be shut off entirely for half the cycle...this is assuming the use of an LED rather than a bulb.
I know what I'm trying to say, but I'm having trouble describing it. You'd probably use a capacitor to smooth it out, but a bridge could be used as-is. It'd be a huge improvement (but imperfect) over the existing situation.
