ok i have had these in my car for a while now and i just got my car back and i went to turn on my lights and my guages didn't light up. but when i hook up a contestant 12 v source it stays lit, but when i hook it up to my light switch it only stays lit up when i have my park lights on and when i turn my lighs on it turns off, i have tried different ways of hooking it up and still a no go when i turn my lights on, any idea where else i could try to get this thing working? any info would be great
