Why do your park avenue brake lights work but the tail lights won't?
Check bulbs they are double filamented with larger filament for tailights
Check fuse for parking tail and dash lights
May be a bad switch
Have you upgraded any lights to LEDs? This answer can apply to any car with this problem but only if LED lights are used. This can be caused by LED 1157 tail/brake combo lights. The problem is that the tail and brake lights are not always as isolated as they should be. When the brake lights are powered on the tail light terminal becomes live. This voltage will power up the park light circuit ie…
What do you do if your tail lights do not work while driving though brake lights work fuses and bulbs are good?
What could you check if your drivers side brake light works when headlights are off but not when on?
What is the problem when head lights are on and the tail lights dont work but the brake lights work?
If the headlights are on and brake lights work but not the tail lights, it is possible there is a short in the electrical wires. Another cause for this could be that the tail light bulbs are burned out. Most vehicles have more than one bulb inside the tail lights to control different lights at the same time.
