I just measured the voltage and power draw:
SR/F headlamp electrical test Voltage 13.1
terminal 1 2 3 4 [bar between 3and4]
Main Beam
Amps 0.18 1.61 0.45 0.45
Watts 2.4 21.1 5.9 5.9
Dipped Beam
Amps 0.18 1.38 1.19 0
Watts 2.4 18.1 15.6 0.0
Summary: Halo Main Dip signal?
2.4 21.1 15.6
label: 1.6 20.2 14.7
On SR/F Dip stays om when Main beam activated
Therefore: Wattage to match for round headlight to fit fairing:
35 15 Watts
So the rating on the back is spot on, but doesn't count the main and dip being on together.
The forth pin is weird, and I presume its some sort of signal line, maybe not DC, which is what I was measuring.
Any body any ideas about this? pete.
