Long story short, reversed into a brick wall at a slow speed which caused some light scratches and a crack in the right tail light. The reverse parking sensors now no longer work. They normally beep when put into reverse and then beep according to how far you are from any object behind you. The beep on initial engagement sounds different now (different tone) and no longer beeps at all after the initial beep. There are no scratches or damage to the circle sensors from what I can see, does anyone know why the unit itself has stopped working? Are the reverse sensors that sensitive to damage?

I'm going to buy rear tail lights and replace them myself, does anyone know where the cheapest to buy would be? Or where I could just get a single right rear tail light?

I will get the light damages fixed by a panel repair shop, hopefully the cost wont be too expensive. Pretty bummed at the moment.

Any help would be great, thanks all
