Hi, we were just at Bontrager's Surplus Inc yesterday, and Hubby got tailights for our pop up - getting it ready to sell.
They're in White Pidgeon, MI; but also sell on Ebay. It was our first time there, and they couldn't have been any nicer! They pretty much have any part you could need, and help you figure it out too!
Bontrager's # 1-866-483-7017,

Good luck!
