I've got a problem with my lights. The nearside headlight, sidelight and tail light are all not working. I've checked the bulbs and they're all fine. The sidellight and tail light don't work when the parking light switch is used either.
I've checked the headlight fuses, and they're okay. I've also checked the relays, and there's power going through them (I can hear the relay click when switching the lights on/off). I also tried swapping the relays around, and noticed that when the r/h headlamp relay is removed, both headlights come on but are very faint.
Main beam/flashing the lights are unaffected, and the foglights also work.

Anyone got any ideas as to what to check next?
