I treat it like a regular stop light. But then, when there's a red light at an intersection with a bike lane, I will usually scooch over to the left (taking the trafic lane) and get in line with any waiting cars in order to avoid being right-hooked by turning motorists. Once I get past the intersection I'll merge back into the bike lane (provided that I'm in Little Rock where a local ordinance stipulates an MBL rule), otherwise I'll just ride with the flow of traffic... bike lanes here in AR are few and far between anyways.
