Perhaps something in the gear shift that turns on the lights when in reverse position.
There is a switch on the shifter or trans that turns on the lights when the vehicle is placed in reverse, it is out of adjustment or faulty. And don't forget the bulbs or fuses as a cause.

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.
It can be connection wires, bulbs or fuses.

Like many engine and diagnostic parts of the 1990 Toyota Celica, the tachometer needs the assistance of a fuse to operate correctly. Check the fuse box for a blown fuse for this instrument.
