Hi Woozy.
Sorry - I use the FlightCraft and AeroDesigns A340s in preference to the POSky - but I have got their A330-300, and this is what the lights section looks like:
[lights]
//Types: 1=beacon, 2=strobe, 3=navigation, 4=cockpit, 5=landing
light.1 = 1, 7.800, 0.000, -5.500, fx_beaconb , //RED FUSELAGE BOTTOM FLASHING BEACON
light.2 = 1, 0.200, 0.000, 14.500, fx_beaconh , //TOP FLASHING BEACON
light.3 = 4, 82.500, 0.000, 8.000, fx_vclight ,
light.4 = 2, -40.200, -93.100, 13.380, Opensky_airbus_strobe , //PORT WING WHITE STROBE
light.5 = 2, -40.200, 93.100, 13.380, Opensky_airbus_strobe , //STARBOARD WING WHITE STROBE
light.6 = 5, 18.000, 27.000, -4.000, Opensky_wing_light,
light.7 = 5, 19.933, 8.827, -4.368, Opensky_wing_light,
light.8 = 5, 18.000, -27.000, -4.000, Opensky_wing_light,
light.9 = 5, 19.933, -8.827, -5.368, Opensky_wing_light,
light.10 = 5, 19.700, 19.000, -6.000, Opensky_nacelle_refl,
light.11 = 5, 19.700, -19.000, -6.000, Opensky_nacelle_refl,
light.12 = 3, -116.000, 0.000, 11.420, Opensky_nav_yellow ,
light.13 = 2, -116.000, 0.100, 11.300, fx_strobeh ,
I've added in capitals what the relevant ones are. The white wingtip strobes look good to me, but they're different to the ones you mention. Might be worth getting the A330 package and using those effects and effect names instead.
