You put in that awesome triple gauge pod, but in the process you lost your beloved clock! What to do? The Prosport digital clock is a 52mm gauge-sized digital clock, complete with sweep-second LED illumination! (The band around the outside fills up and then restarts once a minute.) Available in amber or blue LED.
Tech tip: The clock displays 12-hour time by default, but you can switch it to 24-hour by removing the "clock" sticker on the back and pushing both DIP switches down.
