Update. I called Holdens after a short discussion it appears that there should be a dust cover with each lamp.
Initially the guy thought I was talking about the white spot lamp covers, rather than the rubber dust cover that fits on the rear of the unit and covers the headlight bulb.
They will send me a replacement dust cover.
