I belong to a car club & we are restoring an old school bus. These rings are just what we needed to hold some of the lenses in. Perfect! 437265

Ask the Experts about this Optronics Accessories and Parts

Do you have a question about this Accessories and Part?


  • What is the Difference Between a Snap Ring and Retainer Ring for a Trailer Tail Light
  • There really isn't a difference. Snap-ring and retaining ring such as # 410-21 are two names for the same thing. If your tail light looks like # ST40RB then use # A40SRB. But you mentioned that the light was 4 inches, which is what Peterson light # 429800 is. So for that light use # 410-21. Shipping can vary depending on the option you choose and where you live. So take a look at the link to the right that explains more about shipping and how to determine cost.
