So I have been working on upgrading the rear tail/turn signals on my 2008 A3 to LED Bulbs. I installed the rear turn signal lamps along with a load equalizer for each one. All working fine. When trying to upgrade the tail/brake light lamps (Left side pin 1,pin 2-Right side pin 3,pin 4) the inner bulbs(closer to center of car L-pin 2,R pin-3) turn off after a few seconds when powered on. Do I need a load equalizer on each bulb? Is there another option that doesn't involve me having to install...
