Bad bulbs can be the cause of your reverse lights not working on your 1999 Toyota Tacoma. A problem with the reverse switch or bad wires can also be the cause of your reverse lights not working.

every vehicle must have brake lights to indicate that the vehicle is stopping. with no brake lights the vehicle can cause a rear end collision.
Yes, on a 2001 Tacoma it was a blown 5 amp fuse in the separate harness dedicated to the trailer lights. I did not realize Toyota Tacoma's came with a separate harness and fuse block just for the trailer lights/harness (this is separate from the under dash (#1) and under hood (#2). On a 2001 Tacoma , it located underneath the driver's side rear jump seat next to the factory tire jack.
run a wire from battery positive to an inline fuse, then to a switch that you have to install in your dash. from the switch to the lights, then to ground. turn on switch, lights should work.
Check the alternator capacity.
