Use tube kit P/N 07080-00 for this item. 12V or 24V light kits sold separately, reference P/Ns 210341 (12VDC) and 210342 (24VDC). These single-lead light kits ground to the metal gauge case and are unique to current production Datcon mechanical pressure gauges. Other Datcon light kits listed are not compatible with these mechanical pressure gauges. For panel kits and other options, please see Accessories section. See other sections for matching speedometers and tachometers. Current Datcon mechanical pressure gauges are now produced by our Turotest business unit. They are functional replacements for the original Datcon line. While cosmetically and dimensionally similar, please note they are not identical.
