Removing Lines from Unions

So I am trying to build a rotary lightbar with a kind of older appearance, in order to do this the “light cap” needs to be semi-transparent. I have unioned things before to solve the issue of overlapping transparencies, however for some reason it didn’t fix it here.

Here is what my issue looks like, you can see those ugly lines in the union.

I was wondering if there was any way at all to get those lines to disapear and leave me with a clean looking lightbar. I tried looking up a solution on google but found nothing, and my friends don’t know how to fix it either.
