Wanted to provide some closure on this thread as I was able to finally resolve this issue -- I purchased a new (to me) housing from a seller on eBay and it seems to have done the trick. Nice uniform white light coming through the DRL angel eyes now. Quite the pain to chase this down and resolve but glad its done. Pic is prior to the refinishing of the lens and adding XPEL so it still looks somewhat rashed up.
