Check stop light switch - usually located at the upper end of the brake pedal under dash
I am sorry there needs to be more info.on this....are you saying when you have the flashers on and apply the brakes that the hazard lights go out??
to warn the drivers behind your automobile that you are slowing down
If the back dash light will light when the brakes are applied but the two tail lights will not light up, there is probably a short in the wiring somewhere. It could also be that the fuse for the brake lights is burned out.
In the back should be tail lights which always come on when the headlights or parking lights are on, and stoplights which come on whenever the brakes are pressed. The stoplights should be brighter than the tail lights, but they should be separate.
Bad ground, usually at the rear lights.
Fog lights are in the front; they are commonly referred to as "brights" because they are the brighter of the two standard headlights. Brake lights are in the rear; they light up when pressure is applied to the brakes or when the car is in park or reverse.
Most probable a broken bulb somewhere.
If you just barely touch the brake pedal the brake lights will come on but the brakes will for all intent and purpose not be applied.
There probably is only one cause for your interior lights to go on when you apply the brakes. There probably are brake light wires and interior wires that have warned together.
this car may have separate flashers for the turn signals and the emergency flashers
