Motorcycle rights group supports stop-look-go legislation.

You don't need any new law in California. The vehicle code already says in Section 21800 (d)(1) "The driver of any vehicle approaching an intersection which has official traffic control signals that are inoperative shall stop at the intersection, and may proceed with caution when it is safe to do so. This subparagraph shall apply to traffic control signals that become inoperative because of battery failure." If you motorcycle won't operate the light, it is inoperative. Of course it's up to you to proceed safely, just as it would be at a stop sign.
