One thing I did note while loading each chain file, is that the lighting functions kept changing. The beacon did not work at first. Then, it came on with a load. Finally, it is back off again when the final chain file loaded.
I swapped the marker lights while searching for why the green front ones didn't light? When I plugged them into the rear socket they lit. So I put the red into the front socket and they lit too? I think they're just messing with me!!! ????
So Bruce, it seems important to find a soundfile and chain file that supports the functions you're after as GRJ stated.
and finally, another video....
