16,000 Lumens Spot Lights to complement 2017 Led headlights

[Lord Popgun]

Total circuit current, in theory, would be 120 watts. But you don’t want to run a circuit at the circuit breaker rated amps. In any case, the tail light is 5 watts when the ignition is on and 21 watts when the brake light is on.

So, 120 minus 21, minus the amount the meter consumes. I don’t know how much the meter uses. I could easily find out on my 2013, but your bike (2014 and up) has a serial data buss that communicates with the ECU. That means there is a data transmitter/receiver. I doubt that will consume much, but will use some power.

Also, when the bike is running, the voltage is 13-14.5 roughly so take that into consideration.
A few quick calculations show you only would have around 7-8 amps to play with. If you run the breaker with no overhead it may (will) get hot and trip.

The accessory connectors are not really for loads that pull any real current and I would be leary of using them for lighting like you want.
