each those wires are coming out of the thick black & red wires that are coming out of the bar. there is two small red wires coming out of thick red wire and two small black wires coming out of thick black wire.In my experience with the dozens of them I have worked through, it is common for their to be extra plugs in them. Without photos of where the wires trace back to, I won't be able to give you a better answer.
Are they coming out of those on the interior of the bar under the metal lid or on the exterior? I don't think those are wires for the alley light. Are there any functions not currently working on the bar?each those wires are coming out of the thick black & red wires that are coming out of the bar. there is two small red wires coming out of thick red wire and two small black wires coming out of thick black wire.
I agree, those aren't "heat shielded" so they shouldn't be for the halogen options. I have only messed with these a bit, @Jennifer Rose Towing and @tsquale are better sources, but I can see in your bar the other halogen option has the type of wire jacket I'd expect. These don't look like that.Are they coming out of those on the interior of the bar under the metal lid or on the exterior? I don't think those are wires for the alley light.
