Can a single color be changed to a dual color light bar?

[Theweda123]

I have a feniex fusion-s 800 light stick that came with a converter that has all white lights but just found out that I can also run blue lights as well. My question is can I add or change blue lights to my light bar without having to buy a brand new one?! It’s still brand new in the open box but past the return period.

You can't turn a Fusion-S into dual color, because Feniex doesn't make dual color anymore. You can use the housing, but you'd have to replace the modules, and the flasher.
