Hello, everybody. Steven here with etrailer.com. Let's take a look together at a replacement snap ring for your four-and-a-half-inch round flange mount trailer taillights. Now folks, this retention ring does help secure those four-inch and four-and-a-half-inch round flange mount trailer lights biotronics into their housing. Specifically, it fits Optronix ST40 series lights. Now those lights obviously are sold separately.
It's just a nice snap-on mounting. It's a durable spring construction. You can see it's got the raised portion here, and as far as some dimensions, it's five and one eighth inches diameter overall. And as far as the thickness on the metal itself, it's about one eighth inch thick. Well folks, that's gonna wrap it up, just a quick look at a replacement snap ring.
I'm Steven, thanks for watching.
