snubber capacitor help - halogen lights

    I just bought 3 low voltage halogen pendant lights. Inside the canopy, each
    light has a small transformer with 120VAC primary and a 12VAC secondary. The
    lights cause a tremendous amount of interference on AM radio in the kitchen
    and makes it so you can hardly listen to anything except the strongest
    stations. I am no electronics expert, but I have some RIFA PMR 210 snubber
    capacitors I was thinking of trying across the primary, secondary or both.
    My knowledge is very limited and I have only used these capacitors in my job
    to solve some problems across relay coils.
    From looking around, this seems to be a "X" capacitor (line to line).
    However, I noticed that the interference gets worse when the ground touches
    the shield of the light cable which is connected to one side of the
    secondary. So I am concerned I need a "Y" type (line to ground). Anyway, I
    plan to try the capacitors that I have. Does anyone have experience with
    this problem? Any suggestions on the type / value of capacitors I should be
    using? Is there another way to solve the problem?
    Thank you.
