This doesn't seem to be an easy part to find. I found the following information on http://an.hitchcock.org/repairfaq/sam/strbfaq.htm.
"The MPS2111 (Q3) is a PNP transistor which has an internal resistor network in its base-emitter circuit. These devices are sometimes called 'digital transistors' since they can be used as simple buffers or inverters without additional input components. The values of the series and shunt resistors are both 10K for this particular part."
At another place I found this circuit for a strobe light for a model rocket.
Between the two you should have enough information to sub a transistor and a couple of 10K resistors.

In my area, it seems that every pickup truck or SUV comes with one or more dogs. It's so common that I can only assume that the dog(s) must come with the vehicle. So logic tells me that, if you want to keep the truck for a long time, go for the multi-dog option. Otherwise, if the dog dies, you have to buy a new truck. I have five dogs (4 dogs as of 4/4/2013, RIP Katie), so I'm set for a few years.
