As i did solved the flickering of the rear led marker from sonar (due pmw) with a capacitor, i will try to do it with the reverse light, which is still an incandescent bulb, but and in this thread, i will need a diode for it..
My idea:
reverse light 12V ----------+ ------------ relay coil |

capacitor

reverse light ground -----+----------- relay coil
I did not have the time to do it yet due a lot of work and stress. |
This is what I had in mind:
You have to isolate the charge at the relay from the low impedance of the incandescent bulb.
12V to rev light --------------Light Bulb-----------------GND
