Alright so I've been using a Whelen Liberty light bar on my vehicle but I want the traffic advisory on it. I know it has to be real because I've seen someone have it on his light bar. I'm basically asking, how do I configure the ELS files so that I can have the light bar show the traffic advisory lights? Honestly I've read the documentation and thought it was extra 5 and 6 that was the problem but it wasn't. I also don't think the title matches but I guess it's close enough to what I'm trying to ask. Thanks for the help 

Unless the advisor is mapped into the lightbar, you won't be able to use it.

 

Extras 7, 8 and 9 are the advisor lights, not 5 and 6.
