Any chance you recall where they talk about this? I just ordered a 20" and 50" and I like this option.
Thank you
P.S. I'm searching now, but haven't found it as of this post
I don't recall who but for example I have my "SVT" Fender Logos spliced into my front corner marker lights. Once my running lights come on the "SVT" comes on.
I would think it would be that easy... Run your hot for the Background Radiance Lights direct to the marker lights. Then run your hot for the main setup to your Aux switch. Be sure to check your fuse size and make sure it's good.
Things to keep in mind though - by doing this, your background lighting will ALWAYS be on when your running lights are on. You can only shut them down by turning off EVERY light not connected to the AUX switches.
Also - depending on the color of your background light you may not want this option as you don't want the blues-reds always on regardless of how dim they are...
