I've had a recent intermittent problem with my headlight, the dealer checked it out and was unable to replicate the issue and deemed it OK. They did however supply me with three new relays as a 'just in case' measure. These relays were four pin rather than the original five pin. The parts man said that the five pin have been superceded by the four pin. I haven't fitted them yet so unable to comment on suitability. I'm going to wait until (if) another electrical problem occurs.
