I know the optional running board lights commonly go out, and that you have to order the whole light kit to fix, since individual lights are not sold. I know you have to take off the running boards to replace. I have found a video on removing the running boards, but I can find no specific written instructions or videos about light replacement. I found light kit on Ebay for a $420. (Therr are still 2.listed at this price if you need it.) My mechanic quoted me $1100 to install. What could possibly take 8 hours? Any help here would be appreciated.
