How can I eliminate radio interference from DRLs?

Thanks for the thought, bro, but the noise is white-noise static, and neither its volume nor frequency varies with engine speed. Any other ideas gratefully accepted, although I'll try moving the control module anyway. The control module in under the bonnet, whilst the radio antenna is out back of course, so I don't see the connection, but at this point I'll try anything reasonable.
