Some traffic signals are equipped with an emergency vehicle pre-emption device which allows an emergency vehicle (usually fire trucks and ambulances) to activate a green signal in the direction they are travelling. The white and blue light is used by emergency vehicles as an indication that the pre-emption is active. During an emergency preemption, several emergency vehicles may approach an intersection from different directions.

This light is a transit priority light. When this light is activated, only transit buses may proceed through the intersection. This allows the bus to “jump” ahead of the regular traffic. The intersection likely has a “time of day” timing plan which allocates more green time to the direction of travel with the highest volume of traffic. See similar questions...

At first, all small pets items (with the exception of the Bloodsail Admiral's Hat) were white, which is the "common quality" color code. Blizzard later recolor-coded many promotional pet items in an effort to prevent people from accidentally destroying or selling these ultra-rare items. But many other extremely rare vanity pets remain white, despite the fact that a few are even harder to acquire than some blue and purple pet items. See similar questions...

When I connect my light, the power button flashes and the light sets of a series of slow pulses (1-10) even when the light isn’t turned on, is something wrong with my switch? (also put a version of this in troubleshooting) When the battery is connected, the light runs a self test. This allows our factory (and your dealer) to see our light is in good working order. The number of pulses also tells us which model light you own. See similar questions...

The only other issue is what version of the operating system you run. Macs with lots of memory and PowerMac models can run System 6, 7, and often 8. The Classic and most Compact Mac models will only support a few to several MB of memory, so you will most likely run System 6 or some version of System 7. All of these allow the use of printer extensions (drivers selected by "chooser") for most Stylewriter model inkjets. See similar questions...
