According to the Iowa DOT, the lights aren’t intended to appear blue. The department installed LED lights with a white coating “a while ago,” Iowa DOT said in a Facebook post.

Now, that coating is flaking off, causing the lights to appear more blue or purple

    Same thing happened in Winnipeg. White coating failed early and entire streets were blue. Massive sunk cost issues to replace them.

    needed regular replacements

    So… no improvement with LED in this regard?

    We are Iowa. We’re Iowa. Wereiowa.

    If I knew anything about Iowa, I could probably make a joke there.
