GS550: Enough juice to run twin headlights?

[Guest]

I have a set of Dominator twin headlights (standard wattage bulbs) that I'd like to install on my 1980 GS550. Does the system generate enough wattage to run the extra headlight without negatively affecting operation and battery charging?

Thanks.

I am not sure of the output of your charging system, but you are adding a potential 5.5 Amp current draw (65 Watts / 12 V).
My bike only has ~20 Amp total output (230 W / 12V), so it would be using ~25% of my total current output, or both headlights would be using ~11 Amps. The coils use ~8 Amps, which would not leave much to run everything else. Electrosport claims their stators are ~120% of stock, which would allow a bit more headroom.

Thanks. The twin lights were too wide to fit in the brackets anyway.
