UPDATE: I was able to make contact with Siedlinar via email. They quickly responded, indicating that an update had been made to their product that included an adapter for 5 x 5 vinyl posts. They immediately sent a new set of lights with the 5 x 5 vinyl posts and insisted I did not need to send back the other set. Just installed them, and with the adapters they fit perfect on my posts. Lights are relatively brilliant and look nice. I'm very grateful for the prompt and friendly manner in which Siedlinar resolved this problem.Original Post: This set of 4 solar lights is advertised as "fit for 4x4, 5x5 vinyl posts and 4x4, 5x5, 6x6 wooden posts". It fits 4 x 4 vinyl, and adapters are enclosed for wooden posts. My posts are 5 x 5 Vinyl. I bought these in March of this year but did not get the posts in until September. ebay shows return window is closed, and so far I've found no way to contact either ebay or Siedlinar to obtain the correct adapters.
