Well after fitting some parking sensors that a customer supplied and which only lasted 2 weeks I stumbled upon by chance some electromagnetic jobbies as I didn't fancy cutting holes in my bumper let alone somebody else's only to fail after a short period of time. Anyway today I fitted a electromagnetic sensor and I have to say I was impressed with the results so far and it also covered the side parts of the bumper which is useful reversing into a tight parking space. &#
