I have a Autometer Ultralite boost gauge mounted on my hood which I use a FP gauge. It's been there for a few years now and still works flawlessly. The AM has perimter lighting which isn't great but I have no problem reading it through my windshield so it shouldn't be a problem inside the cab.
The DiP's have better lighting IMHO, with the exception of the EGT gauge. I have the DiP oil temp, boost and egt inside the cab. The oil temp and boost have great lighting and a illuminated needle, the egt gauge doesn't have a illuminated needle and it's a bit harder to read. Might be dating myself here somewhat as my DiP gauges are 4 years old now, perhaps they have updated the egt gauge. Regardless, they work very well. Have not even replaced a bulb in them to date.
