LED Turn Signals

[pekingduck]

The CB1100 turn signal system is different from older 3-wire/running light systems.
Looking at the shop manual, the front turn signals on all 2013, 2014, and 2017 models are only 2 wire. One wire goes to ground, the other goes to the turn signal/position light relay, which uses a total of 8 wires (like on the POSH units).

The relay apparently lets the front filament run at lower voltage as a running light, then at battery voltage as a turn signal, or in the emergency flasher mode. No wonder other aftermarket flashers generally can't work.

The wiring diagram says the front signals are 21 watts, and, oddly, the rears are 15 watt, with a part number specific to CB1100s. Weird.

The screws that hold the turn signals are 6mm.
