2 solutions:

1 - Don't turn on the lights while listening to the radio, 2 - don't listen to the radio when you need to turn on the lights.

Third solution - Separate the circuits.

4th solution would be not to listen to AM broadcast band when the LV lights are on.

By Charlie: Third solution - Separate the circuits.

What will that do if the AM radio is receiving the RFI through it's antenna?

Many of these LV power supply's use switching type voltage regulation. This tends to produce allot of RFI in the vicinity of the power supply. If you can swap it out for a magnetic transformer type power supply and I'll bet the noise will be gone.
