What do these guages work with? Am I right in thinking you need "something" else to hook them up to to work?

Oil temp would be awesome with dual colour LED's that start green and go Red over a certain temp.
I'd say Oil Temp is the most important gauge missing from an E30!

so...
The buttons are very deeply tinted to filter that "white" light into the color of the switch (red for hazard, and yellow for defrost). Remember that light isn't "tinted" by a filter like paint. It's that the other colors are stripped out. So, putting green leds behind a red filter give you almost no light at all. So yea, the button acts as a filter, blocking light not on it's "wavelength". Make sense?
The reason the led's are all one color has to do with the button. The light that is normally behind it is a standard incandescent type bulb that puts out "white" light - and you'll remember from school, that white light is made up of all the colors of the rainbow.Royalratch wrote:dual colour LED's that start green and go Red over a certain temp.

It depends on what you are measuring. These gauges will take a linear signal and display it with out anything else. Oil temp and oil pressure are not linear. But it can do a great job of displaying voltage, wideband AFR, and narrowband AFR.Jozi wrote:What do these guages work with?

I have a voltage gauges form George, quality of his work is fantastic 
I will be purchasing a wideband from him as well

Thanks Steve! I happen to have a few made up (including widebands) that I'll list up soon.

Thank you. I'm building a small (final?) batch of these gauges if anyone is interested. Please email me at: george.graves@gmail.com
