Probably could do that, if you had a set of blinking leds that didn't care about not getting the full duty cycle, or could use caps to smooth out the pwm into something stable enough. Or throwing a transistor and some other stuff on there that can latch it on above a certain threshold. But that's getting more middle or front of the class, not joking around and reading magazines back here.

Reverse lights are easy enough if you just tap the motor leads and set polarity correctly.

At that point if there's room, a dedicated drop-in light controller circuit would be easier. I'm running some that were under $15 that can output for marker lights, running, turnsignal, brake, reverse, headlights (either On or toy-style On / switching Highbeam above certain throttle.) It just pigtails 2 channels between RX and servo and drive esc.

Hazard lights would be sweet, i just haven't found a cheap one that does it yet.
