Well good news but not so good. Usually static is due to a poor ground on an electronic item. The only other ground I can think of that could allow noise would be the antenna ground and the stereos ground. But if the radio works and you don't get static on any function but AM. The issue is in the lamp itself, it shouldn't generate any RF that can escape it but something like a failed capacitor or bad driver circuit is allowing the RF to follow the power lead into the electronics. The only other test I can think of would be connecting the lamp to a different power source and place it near the antenna and see if the static is still there. You might be able to install a noise filter in the line but that may not help if it is also radiating the signal.
