Not a valid assumption. The effective resistance of the lamp would be around 6
ohms for a 27W stop lamp. I'm sure they've made the relay to be around .5 ohm or
less, so the voltage at the lamp would be closer to 12v in a real-world 12.8 -
13.5 volt world. It'd be interesting if you could actually measure one of the
relays, and/or the voltage across it and/or the lamp(s) in your car.

I believe this too, but I also believe whover told you that is/was full of it.

Immaterial. As I understand so far, the relays are in the brake lamp circuits.
Presence of a tail light or whatever in the same lamp envelope is of no concern.

No doubt. Probably the other responders misunderstood the discussion so far.
Is there a part number for the relay on your car? Maybe I can find the specs.
Googling is good, but in this case I'm either not coming up with the correct
search parameters, or there's just too much stuff...
