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.
if all other lights are working, i would start with the reverse light switch.this is usually located on the side of the transmission
replace the light
Usually, there are two of them.
can anyone tell me how to replace the dash lights in my 2003 toyota tacoma prerunner sr5?
there is no fuse for the reverse lights check the netural safety switch it may be out of adjustment or shorted.
a Phillips head screw driver
Hit 'em with a big hammer
check for blown fuses
have you checked the bulbs and fuses
switch on the transmission which sends a signal to the reverse lights when shift is in reverse......... is shot. You need a mechanic.
