This Knucklehead® hung on underneath the car for over 6 months – and it still works!

One of my customers came into the office in our auto repair center and showed me a Knucklehead® that had survived real torture. He's a car mechanic and after doing some repairs, he forgot his Knucklehead on the exhaust under the car he was working on.

After about six months, his customer came in for service, and there was the Knucklehead, still clinging to the exhaust pipe. The owner of the car lives on a gravel road and drives the car every day. We also get a lot of snow here in Sweden and we use a lot of salt on our roads, so that light took a lot of abuse. But the Knucklehead® still works!
