Mike,
Not quite: the magnet for the brush indicator light on the G3/G4 and G5/Avalir II brush rolls will be in a different position depending on the models involved.
The G3/G4 nozzle had the indicator light on the side of the nozzle where the toe-touch control is, while that for the G5/Avalir II had it on the side facing the bag.
Part numbers of the revolving brush assemblies:
156293 = for G3 and G4, brush indicator light magnet is on side of brush roll facing toe-touch control
152502 = for G5 to Avalir II, brush indicator light magnet is on side of brush roll facing bag
152505 = for G5 to Avalir II (stiffer bristles), same attributes as 152502
Hope this helps you!
