here's the kit i bought:
comes with sandpaper (1000, 1500, 2000, 2500), cloth, rubber gloves, polishing compound, and instructions:

here's the good headlight:

and here's the bad one:

here's after (it started snowing, i'll take a better pic some other day):

close up:

it is quite a bit better, but still not like the other one 
here is a scan of the instructions (big image, so it's readable):

i basically just did exactly as it says to do.
cleaned the headlight
soaked the sandpaper
started with 1000 grit (i had no deep scratches, but A LOT of buildup)
side to side, then up and down for the next one, etc.
then circular with the polish
i probably did at least half a dozen runs with the polish and used nearly the whole bottle
a drill with polisher would have helped a ton for the last step(i have one but couldn't find it)
make sure to clean the headlight between each grit level and between each application of the polish
overall it was quite a bit of work, but does look a lot better than before.
also, the reflective area inside this headlight is damaged
(lost much of its luster due to previously having dirt inside the headlight),
so even if the cover was perfectly clear it wouldn't look at shiny as the other one.
