This is what I did. I soldered, tapped and sealed some wires to bypass the taillight assembly design. I was on my 3rd pair of burnt tail lights before I resorted to this fix.
0 problems ever since. I sealed everything so there shouldn't be any corrosion problems. Its not shown on the pictures but I cut the roundish contact points on the sockets of where they meet the tail light prongs.
Should take about 30 minutes to do Botha sides. Hope this helps.
