I can't pull the lights out of their housing after using the key to unlock the light
They come out about an 2 inches
Is it because I have to disconnect the cable from the 12V transformer as there is not enough free cable to remove the light
Although the lights have rusty water in their lenses they turn on for about 2 seconds and then turn off
Would it be possible to drain the rusty water from the lens and dry them fix the leak reseal and reinstall
