Tail Light Issues

Hi Guys

I have a 2004, 318i F/L Beemer. The right rear tail light on body, seems burned out at the socket. I also get intermittent signals from the rear left side. I got 2 x cluster units from MD house, however, I cannot seem to get the Looms for these clusters.
This is a common problem, as I have been told.
Where can I get the Looms, and how can I rectify the problem for future?
I am in Randburg.
Any assistance will be apprieciated, as my wife is driving the car, and seems to get a lot of zap signs when other drivers don't notice her hand signals when turning.

Regards
Paul
