One more electrical demon.....

Odds that all 8 LEDs are installed reverse polarity is very slim. On all of the replacement headlight switches I have seen , there is a extra male spade tang for a chassis ground wire. So you could just place a female spade terminal there with ground wire to ring terminal attached behind the left kick panel. Thus a plug and play chassis ground that remains present even after the column is dropped, panel pulled away from dash, etc...
