RCW states 2 cycles of the light and then proceed with caution. I know which lights on my route will and will not trigger for a bicycle, so I follow the "no cop, no foul" rule regarding the intersection. If it's clear when I'm approaching I'll just go right through. Pretty easy to see for cross traffic on a flat straight 1/2 mile sections with no obstructions, at 5am before most people are even awake around here.
