2014 BMW motorcycle brake tail light PWM frequency duty cycle output question

[poot36]

Hi, I am needing the PWM frequency and duty cycle of a 2014 BMW motorcycles brake light / tail light for a circuit simulation.  I just need the tail light mode but brake light mode would also be useful.  If someone could measure this for me I would be greatfull.  You can use a solar cell attached to a oscilloscope or maybe a computer sound card with the correct software installed so you do not have to take apart the bike.  Mods if this is not the correct place for this topic could you please move it?  Thanks.
