If the fuse keeps blowing, there is a short somewhere. Since the dash and tail lights both go through the headlight switch, I would check the wires from the switch connection all the way to the tail lights, and the dash lights. Somewhere, a wire is crushed to ground or something like that.
Make sure your switch is property connected and is a good switch!
Good luck!
Check your tow bar and trailer brake light wiring. It may be grounded. I had this problem with my 92 roadmaster wagon. Tom.
Blown fuse or the lights are just blown and need replacing.
I imagine that more than likely the problem is going to be easy to fix by replacing the fuse.
If the taillights and dash lights on your 1996 Buick Roadmaster are out, it could be due to a blown fuse, a faulty light switch, or a problem with the wiring or connectors. Check the fuse box for any blown fuses related to the tail and dash lights. Additionally, inspect the light switch and wiring for any signs of damage or corrosion. If these components are functioning properly, further electrical diagnostics may be required to identify the issue.

The dash lights will not work on a 91 Honda Accord if the fuse or bulbs have blown. Inspecting and replacing the fuse is the first step to repairing this problem.
Try replacing the back-up light switch. It is located on the left side of the transmission. It is a common problem.
Sounds like an electrical problem. Perhaps there is a short somewhere. New relays might be needed
There could be many reasons. The most common reason would probably be that the bulb in the third light has blown. Try replacing it with bulb from one of the other lights or a new bulb and see if it works. If replacing the bulb fixes it, then this was the problem. Otherwise it could be build up of dirt or corrosion in the fitting, or a wiring problem.

Alternator needs replacing.
If your brakes lights are not working and all of your other lights are OK try replacing your "brake stop switch". You may have to have either your local auto shop or local dealer replace the switch because it's hard to do yourself. I had the same problem on my Tahoe and replacing the brake stop switch solved it right away.
