The worse thing you can do is use a clicked link on a forum, the leds are bound to be really bad quality!!
I would never ever suggest anyone use leds from a company like the one in the link.
Personally I would go out and look at signs, if I saw one I liked I would go ask the person who owned where they got it from. Much better and safer than clicking on spam links in a forum...IMHO
Also you are aware that for a small fee, you can pay people to write decent forum posts for click bait, sorry but if its a SEO attempt its a bit amateur IMO.
