1978 280z:
When I hit my brakes my side marker lights and dash backlight come on.

I haven't had the car very long so not sure if it's always been like this but I just started noticing it.

Any ideas?

Does it light up but its kinda dim? Sounds like a bad common ground and its back feeding (grounding) through the marker light/dash light circuit.

Maybe not directly relevant, but on my 77 a previous owner had decided it was a good idea to jumper the front markers to the headlights.

I'd take the bulbs out and check resistance to ground, and if they have any continuity to each other. That should help you track it down.
