get a good brand accurate gauge. look into Autometer from Summit racing.
all depends on which series you get. a lot of gauges will have the dim feature.Are the Glowshift gauges I'm looking at not good ones? I usually read all the customer/owner reviews I can find when comparing products. The Glowshift gauge has pretty good "verified" customer reviews on Amazon. The lowest priced Autometer gauge was only $3 more than the Glowshift gauge I was looking at and had perhaps a tiny bit higher average rating. What I like about the Glowshift over the Autometer gauge was (1) the changeable readout color, (2) autodimming at night, and (3) LED vs. incandescent lighting. Also, one reviewer said he had to buy an adapter to get the sensor to fit into his tranny…didn't like that at all. I want a plug and play unit. I had enough problems getting an aftermarket radio to have sound with my Fosgate system (another post).
