I can tell you a little bit about them, but I don't know the bulb type or how to change them.
They are "city lights" (what euro manufacturers call similar lights) or parking lights - note that when you turn on the low beams, the amber DRLs go out, leaving no other parking light on the front of the car except for these small bulbs. I think that on some Caddies, the square amber lights in teh bumper serve as DRLs and Parking Lights and Turn Signals - but on the SRX they are only DRLs and Turn Signals.
I haven't yet had to figure out how to get to the back of the light assemblys for bulb changing puposes, but I imagine some combination of grill, front bumper, or fender liner removal is required.
