I spoke to my contact at Optronics and they informed me that the Heavy Duty Magnetic Tow Lights part # TL21RK uses a 20 gauge wire. This will be standard for most magnetic tow lights for the exception of a few which can use an 18 gauge wire but that would be the thickness wire used in a set of magnetic tow lights. view full answer...
I checked with CE Smith on the spare tire carrier # CE27310G. The mount itself is galvanized but all other parts (the hardware) is zinc plated. I checked all of the spare tire carriers we offer, see link, and all similar models also use zinc plated hardware and all others except this CE Smith carrier also use zinc plating on the main mount. view full answer...
