I was under the impression that these were Bluetooth and you could hook them to your phone with an app my mistake but other than that they look pretty durable the only question I have is red and white wire here where I'm from White could be positive and red could be positive so which one is which?

have not yet installed but have applied power and theses things are nice bright color changing with remote.
