I claim the ornamental design for an motorcycle indicator light, as shown and described.
FIG. 1 is a side view showing my new design;

The broken lines showing an extension of the motorcycle indicator light in FIGS. 1-4 have been shown for the purpose of illustrating environment that forms no part of the claimed design.
The broken lines showing the arc shaped surface in FIG. 1 forms no part of the claimed design.
