Ok, now that I can partially read a wiring diagram, it seems that every exterior light passes through this "Exterior lamp Failure Monitoring Module", Does this mean that this MODULE also handles the signal/hazard blinker circuitry? I don't see any separate control boxes on the diagram.

Oh wait... as i type this I see a "Combination Relay"... so which is responsible for the blinkers? Can I bypass the "Failure Monitoring Module" altogether? What is this module responsible for aside from a Bulb Out warning?

Lamp module ONLY monitors current consumption on each lighting circuit.
Then turns on the bulb-out lamp if needed.

Thanks! That's one less module to worry about.
