Just got some Reverse Indiglo Guages Q: How can I test them

I purchased these reverse indiglo guages through, I've seen them in person and they look amazing. I want to install them next week but I only have 1 week to return or exchange them if there are any problems. My question is how do I test the guages outside the car? After I connect the guages to the switch I am left with two power wires. I have a voltage regulator so I can connect the wires to it at whatever voltage nessary? What is the easyest way to test them? What should I set the voltage regulator too? Or if there is another way to test them please tell me.

Just set the regulator to 12 volts and wire the leads to the pos. and neg.
That is all.
connect it to a 9volt battery, as soon as I opened it thats what I did.
Thank you both, I used the 9 volt and it worked great. Saved me some time having to unpack my voltage regulator (Moving to a new house in 2 weeks). Man I love the glow on these guages, cant wait till I install them. One question, I noticed a noise comming from that little black box when I had the unit switched to blue, if I switched it to green it went away. Its not much of an issue, its quiet enough that any engine noise will drown it out, just wanted to find out if that was normal.
Mine makes the same noise, I dont know why, but from all the music or engine noises in my car its not noticable
The little black box is a power inverter, and that is common from them to make a little hmm. My indiglo gauges do the same thing.
mine makes a high-pitched sound, like some of my neon transformers.

I would expect it to make the sound, mostly all transformers do, but what confused me is that when I switched it to green the sound went away. It only makes the sound when switched to blue.
Ok here is my guess why the sound appears to go away. My indiglo gauges are the ones that can be 7 different colors basically different shades of green and blue combined, the unit actually makes a different tone for each different color with the green generating a low pitch tone and blue making a higher pitch tone. Now I have no idea exactly how indiglo works but I imagine the inverter produces and electrical sine wave, similar to AC power, at a certain frequency to excite the material on the guages which produce a particular color. As the frequency of the sine wave is changed so does the color of the gauges and the pitch of the tone produced. I believe the reason why when you change to green that the noise goes away is two fold. One the the tone the is being produced is a lower pitch and is simply harder to detect, and two because you at testing it using a 9V source instead of 12V source, the tone it is producing is that much quieter. This is purely my own hypothesis, but I hope it helps.
