On my driver side some of the amber LED started going dim last month, now some completely went out. I measured voltage on the last light on the harness that is easiest to get to and are getting good 12.8V with truck not running. Some I just can’t reach. I was thinking it’s corrosion on the harness but now seeing good voltage not sure.
Any ideas what should I check first before replacing them? Also what’s the best way to dismount these lights?
