Wiring Motion Sensors Lights?

Can I wire 2 lights with their own sensors that turn on both lights when either on of the sensors 'trips'?

Although I've never tried it I'm going to say that it will not work.
The reason is this ; if you connected the power into sensor 1 at
light 1 then connected power out of the sensor to the fixture at light 1 & fixture 2 then ran power to sensor 2 and power out of the sensor to fixture 2 you will be creating what is called a backfeed. As the power comes out sensor 1 to light 1 & on to light 2 it will run backwards thru sensor 2 and back to where the power originates at fixture 1.Basically its as if you are wiring two hot wires together and causing a dead short .

Yes, you can do this.

Wire the lights in parallel and the sensors in parallel.

Take the hot wire and run it to the line side of both sensors. Take the load side of both sensors and wire them together and to the black wire on both fixtures. The white return is just connected to the returns.
