Hey everyone, I am having a bit of an issue with my brake lights on my Honda Accord. When I press on the brakes with the headlights off, only one of the tail lights turn on (as seen in the first picture). However, when I turn the headlights on, all the tail lights and only one brake light turns on (as seen in the second picture).

I've tried changing all the bulbs and the stop light fuse in the fuse box looks good. Anyone have any idea what could be the issue?

 

You might look at the ground for the right side lights.

 

one filament of the bulb is broken, the one that works with the brakes. pull it out and check it,

follow these instructions.
