Weird indicators

Wonder if anybody has had this problem. I'm in the habit of testing the indicators and brake lights whilst warming the bike up before a ride. When testing the indicators I've noticed that the two front ones come on simultaneously at half brilliance when switching between left and right, the back ones operate normally. After a switching between left and right a few times they start working normally. Weird ???
 
Given that the front and rear indicators for each side are wired in parallel, and the problem is only affecting the front while the rear globes working OK, it seems unlikely that it would be an issue with the switch.

The problem has to be something associated with both front indicators. I suspect the only thing they have in common is earthing. The indicators are on a plastic fairing, so need to have wired earths. Presumably their respective earth wires come together somewhere and then go back to a point on the frame. I guess that earth connection to the frame has failed, and each of the front globes appears to be finding a path to earth through the inactive globe on the opposite side. Not having a RGS wiring diagram in front of me I'm not sure exactly how that would happen as it seems contrary to how the flasher relay would operate.  But I'd be checking earths if I were you.
 
Check the seating of the front indicator bulbs and the warning light bulb.

The front and rear indicators are wired differently.  The rears recieve their current from the switch and are earthed in the "normal" manner.  The fronts also get their current from the switch, but are earthed against each other via the warning bulb, ie, the earths from both front bulbs connect to both sides of the warning bulb.  Sounds strange, is strange, but is normal pratice if only one warning light is used.

Thanks guys.
I have a wiring diagram and I'll check tomorrow, most probably one of the connectors on the back of the instrument cluster.
