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.

Then I'll guess that it is noise generated by the control module. If the module is not sending full power to the running lights, it is probably using some form of PWM which can be quite noisy. I'm guessing that the wiring running to the rear lights is close enough to the antenna to cause problems. The only solution I can think of is the shield the wiring.

But I haven't seen a schematic or wiring diagram for your lights, so take the above with a grain of salt. I'm just making a SWAG.

Dude, that must be it. I think you nailed it. I will pull up my rear floor tomorrow and FIX THAT THING!

Thank you thank you thank you!

Whoa! I'm just guessing. Get some confirmation before tearing anything apart.
