Locate the TNS relay in the fuse box in the engine compartment. You're probably not going to tell by looking at it, so I recommend switching this relay out with another one of the same size, like the horn. Also check the fuse for TNS, I think it's a 30 amp, one of the box-style fuses. You can also check the mini-fuses for your tail lights, there are two. The dashboard lights and tail lights both run from there. (I just fixed this problem on my 1999 Kia Sephia last night. In my case, it was the 30 amp fuse.) Locate your fuse panel and check your fuses
Check for a blown fuse

There are two fuses that control the taillights on a 1998 Kia Sephia. Each fuse controls one taillight and are located in slots 33 and 34.

To replace the dashboard lights on a 2000 Kia Sephia, start by disconnecting the car battery for safety. Remove the dashboard cover by unscrewing the necessary screws and gently prying it off. Locate the burnt-out bulbs in the instrument cluster, twist them counterclockwise to remove, and replace them with new bulbs. Finally, reassemble the dashboard, reconnect the battery, and test the new lights.
