Where is the tail light fuse for a 2004 Honda Odyssey?
 

It doesn't seem to be listed in the Owner's Manual. I see back-up lights, headlights, interior lights, etc. But nothing referencing tail lights or brake lights.

Check For Fuse Links. Check Under The Hood For A Main Fuse Box, Or Maybe You Just Have To Replace The Bulb.

fuse #47 a 20amp unit in the "Under hood fuse/relay box"this box has 2 heavy wire going into ita 120amp fuse next to those terminals and 6 small fuses in the corner (along with other fuses and relays)#47 is in the middle of the row closest to the terminals.it handles the ABS, cruise, horns, ignition key light and more.I'm guessing it is a bulb issue since the horn would be an obvious giveaway and you didn't mention it.
