hope you can easily resolder your LEDs
When I bought a second hand A3000 both leds didnt work
dismantling the small board showed BOTH leds were pulled away from the curcuit board and all traces broken

So I glued the leds back onto the board with 5minute epoxy, then used some electrically conductive paint. I painted around the led contacts after scraping back some of the curcuit tracks.
This was enough for the leds to work, yay!
Some auto shops sell conductive paint for rear window demister repair, handy hint
