For fun, I just measured the current of my trailer's LED lights. At
12vdc:
brake lights: 100ma each (has 8 LEDs in each one)
tail lights: 80ma each (has 12 LEDs in each one)
side marker lights: 30ma each (has 4 LEDs in each one)
So they apparently put 4 LEDs in a series string, with a dropping
resistor or circuit to take up the rest.

Yep, for 12 volt DC systems, either three or four LEDs in series is
pretty normal. Those numbers make far more sense than the original post
in this sub-thread that said 30mA for turn and brakes.
