Colour coded reversing parking sensors

We have had parking sensors on our new motorhome ( had them on previous van and really felt the beniefit) 
Even though our new van came with rear reversing camera we missed the parking sensors especially when reversing out of our drive as we have a very high security wall.
We stopped overnight at Towtal in Stoke en route home from the Xmas meet at Donnington. Really pleased with the job and the colour coding as it was difficulty to match on our bumper. We feel safer in sites where children often hang around the rear if the van on small scooters etc even though we always check before setting off.
Just sharing ......Marie
