    Default LED reverse lights always on.

    So i wanted better lights when going in reverse, since i cant really see that much with the window tint.

    I got myself a pair of this


    When installing them ... 1st problem. The right side has the polarity reversed. So the light wouldnt come on ... it took me a while to figure that one out. i got my soldering iron out, and reversed the cable connections.


    They looked great, and really bright. All was looking good ... until someone told me ... hey your reverse lights are on all the time. I checked out, and yeah they were on. Quite dim, but on. I got my voltmeter and measured 5v in there. I puted back the original lamps ... and still measured 5v but they werent on. So i figured out this is the check panel sending 5v to test for burnt lamps. But since the LEDs work at low voltages, they were going on at 5v.

    Now the question, anyone knows how to fix this? those lights are really great and i would like to use them. but i wont have them on all day long.
