Check which lights are broken
You might need someone to help you out since you can't really see your lights while you're in the driver's seat. Once you've verified which light or lights are broken, then you can proceed to troubleshooting the problem. Most of the time, if there's only one bulb that won't light up, then it probably has a worn out bulb or has faulty wiring. But if both lights are out, then you might have to take a look at your vehicle's fuse as well.
Your vehicle's lights won't last forever, and they'll burn out once they've reached the end of their service life. Check your tail light's bulb by removing it from the assembly and inspecting the filament wire inside. If you notice that it looks burned are has snapped into two, then you simply have to replace the bulb. However, if you think that the filament still looks good, then you should check for other problems in your tail light assembly.
If your tail light assembly simply won't light up, then you might have a blown fuse. You'll need to inspect your vehicle's manual so you could easily locate the fuse for your tail lights. Examine it and see if it needs to be replaced. If the fuse is okay or the lights still won't turn on after replacing the fuse, then you might have some problems with your tail light's wiring.
If both options above haven't solved your problem, then you need to take a look at your tail light's wiring. Make sure that all connections are attached properly, so you can rule out improper installation. You'd also want to use a multimeter or even a test light to determine if there's a broken wire in your tail light assembly. Damaged wiring cannot be easily fixed, and you might need your mechanic to take a look at it instead.
