I have a all BF guages, a boost guage in my jdm pod and exhaust, oil and water temps in my middle air vents, and even when sun is directly on them, I have no issues with seeing what they say.Topper said:Wouldnt go for the BF guage (black when off), when the light shines on them they are meant to be hard to read.
I would say get oil temp first.
