I have replaced every fuse in the fuse box and all the bulbs in the tail lights, but when I turn on my lights at night only my headlights work. When I press the brakes my brake light will come on but my tail lights will not come on for nothing.

Hello,

I would say the headlight switch is not working, but to confirm the issue use this guide to check for power coming out of the switch to the brown wire.

Please let us know what happens.
