Is the warning set as a high or low warning ? i.e. warn if oil-pressure is BELOW a specific value or ABOVE ?

Asked by: BigMike
Hi Mike, the warning point on the Ultra-Lite Oil Pressure is below. So if you set the warning at 15 psi, anytime the pressure is below 15 psi, the light will be on. Our Elite Series, which offers only 2-1/16" gauge options, will offer 3 regions for different colors; for example, 0-20 psi can be set for one color, while another color can be set for your operating range, then a different color for a high region.

Can you splice into the wiring harness to provide a larger warning light?

Asked by: KLawre2685
Thank you so much for contacting us. Unfortunately there is no output on this particular gauge, so there's no way to add a different warning light. There is a Pro Control output available on the Sport Comp II Oil Pressure gauge w/ warning and the Elite, SpekPro and STACK Pro Control gauges which can be used to supplement the existing warnings. It's worth mentioning that the Elite, SpekPro and STACK gauges all have full dial color change warnings rather than just a small light, which may make having an external warning a moot point. Hope this helps!
