I have a 2000 chevy silverado with a maual trans. The reverse lights won't come on. All other lights work, I've switched the bulbs out and checked the fuses and they are all fine.

Check the switch that is under the dash on the brake pedal arm.

Check reverse light circuit, possible switch on transmission or burned-out bulbs. Is there power to the bulb socket when the key is on and trans in reverse? Use a test light to check for power at the connector.

-Check "headLight fuse"
-Check connector at the headlight.
-Check the bulb. (It could burn out)

disconect the reverse light switch wires from the gearbox & bridge. If the lights come on it is a faulty switch.

Have you checked the brake light switch by the brake pedal?

if the bulbs are good, then check the signal from the transmission range switch.you can check that at the bulb socket with the park brake set, the key on/engine off and put trans in reverse. use a test light and check power in the light socket. no power indicates bad fuse, bad wiring, or bad range switch.

It could be the Neutral Safety Switch or Trans Range Switch located on the side of the trans where the shifter cable attaches. Check it and see if the wiring plug has been hot or deformed. I would have it checked first. Don't just go buy one and toss it on because I said to check it. I don't want you to waste money guessing.

did you test for power to the bulbs, possibly a bad ground connection for the bulbs, or the selector lever is broken reverse sensor is usually on the trans

bad switch or out of ajustment

there is a reverse switch in the transmision 22 or 24 mm nut.
