You might have a connection problem with your LKM or Lamp Control Module. It is in the fuse box on the left side of the engine bay right next to the firewall. It should be marked LKM. Make sure it has a good connection.
Some individuals have indicated their LKM has developed elec. contact problems and they have had to take it apart and resolder some of the connectors.
Other than checking bulbs and fuses, I would start there...

: When I switch on the low beams, all the dash and obc lights, etc dim slightly. Low beams don't come on. High beams fine and no dash light weirdness with them.
: Haven't checked the obvious such as both low beams being burned out .... but the dash light behavior is odd. Owner's manual or fuse/relay cover don't mention which relay is which. fuses fine.
