Rick is right. The .:R has LED's as opposed to bulbs in the standard halogen lamps, so could cause bulb out errors. The .:R's DRLs also dim when you turn the parking lights / headlights on, so it would need coding to get them to work properly.
You could always turn your original DRL's off and just wire you new lights directly to an ignition live. That would be a bit (make that a lot) half arsed, but then again, an .:R lookalike is not to everyone's taste either.
