You probably have this IC:

Or something similar one but it does not matter much because it fit your PCB arrangement.
As you can see from it the LED peak current is set by parallel connected \$R_{S2}, R_{S3}\$ resistors.
And this current will probably be equal to \$I_{LED} \approx \frac{0.6V}{2.35\Omega} \approx 250\textrm{mA}\$
