I'm currently running these gauges in my ZX. Oil pressure, EGT, and oil temp. Here's my take on them...not so great during the day, they are hard to see. I still like them, looks awesome at night. I mean during the day you can still see the gauges, just not as bright as I thought. Not like the Defi. Well, take a look for yourself. I wish I had some night shots.
