Hello,


How to change the usual rear lamps, to LED in the Audi A5 2007? Old beam lower lights has 4 wires and the new 7 wires. The old upper rear lamps have a 3 wire and new 4 wire.
I saw that they were ready sets, but only with the upper rear lamps need to run wires to the module. Is the lower beam up bridges? Has anyone instructions to change the rear lights?
