TAIL LIGHTS WORK BRAKE LIGHTS BOTH WENT OUT - 2000 Dodge Stratus

Check for defective fuse for a start. brake lights on different circuit so shouldn't be affected

The brake lights and tail lights use the same ground. So if the brake lights work the ground is good.
There is a relay and then a fuse for each side.
I would check the sockets with a meter to see if the circuits have power with the parking lights on.

Check your fuses. I had the same problem with a 90 Honda civic. Dash lights went out, tail lights also went out. Replaced 1 fuse and all came back on.

You should have the computer scanned for trouble codes for the warning light.
As for the tail light, I would check the socket with a test light or meter to see if the socket is getting power for that circuit. The brake-turn signal circuit of the bulb is different from the tail light circuit.

Bulbs need replaced, your brake lights and turn signals work off of half of the bulb, while your tail lights work off the other half. It is either your bulbs need replaced, or a fuse went bad, but it is definitely something simple.

check your bulbs brake and tail light the same bulb ?

The odds are the one fuse is blown for the dash and the tail lights. And the wrong bulb may have been put in for the brake light. The brake light is feeding back into the tail light circuit causing the fuse to blown out.

Change out the bulbs with OEM bulbs and replace the blown fuse. That should fix the problem.

sounds like you put the wrong bulb in, that will make it blink fast. re check

if its not the fuse then you have a bad headlight switch

Brake light switch, located on upper brake pedal should be checked, that is most likely your brake light issue, but U say tail lights aren't working, but running lights do, tail lights and running lights I would consider to be the same, so can u clarify that for me? Let me know how the u do w/ brake light switch, and if u have issue w/ tail lights?
