Dead short to ground. Probably at one of the light sockets. Remove all affected bulbs, check sockets, and install bulbs one at a time until fuse blows, at least you will have an idea which area to investigate further
What would cause your fuse to blow when you turn on your lights on your 1993 mazda 323 the fuse to the tail lights on dash lights blow?
There is a taillight fuse in the fuse panel.
Same as parking/dash lights
If it's anything like my 92 Sunbird, (and they do have the same inherent problems), they are leaky cars (water wise) and it's probably wiring. There's a grounding problem it sounds like. I used to have a similar problem in my 92 when I used the cigarette lighter, it would blow the taillight fuse everytime. Replaced the cigarette lighter and problem went away. See, the cigarette lighter was rusted and the ground was faulty, so it would ground to the nearest fuse (which was taillight fuse) overload it, and blow the taillight fuse. Your parking lights are probably not grounded properly and it is doing the same thing my cigarette lighter was. Is it just me or are these cars just like the old Ford Tempo's and Dodge K cars, very reliable for the most part, but very leaky?!
you've either lost both taillight bulbs, or, more likely, you've blown the taillight fuse.
Honda dashboard lights are powered by a single fuse. The taillight fuse keeps the dashboard, taillights and hazard lights safe. If any of this units cause a short all of the components will not work.

Bad switch?
there's a short in the wiring or in the fuse box

The fuse box for the trailer lights are under the hood (drivers side). Have to look in your owners manual to find the correct fuse.
In a 2000 Saturn, the taillight fuse is typically located in the under-hood fuse box. You can find this fuse box near the battery, with a cover that lists the functions of each fuse. Look for the fuse labeled for the taillights or rear lights, which is usually a 15 or 20 amp fuse. If you're unsure, consult the owner’s manual for specific details and fuse diagrams.
