The reason i think they say u cant fit them is because the trailer brake controller will cause the balb warning to go off because of the extra load that it takes off the brake circuit. (these cars check the globes if there blow and bring up a warning on the dash if it see a balb out) There is away around this one live with the car telling u that the balb is out or two u need to fit a diode between the centre brake line to the left and one from the centre to the right and have a wire connecting between the two diodes that the controller picks up this stops the warning coming up, im sure that made no sence so il try and get a diagram up here so it makes sence.
