@Ansett747 | Jonathan - what happens when you switch on the parking lights only? Does that side light up at all? Or is it super bright?
If it lights up super bright, you may have the wrong type of globe in there.
If it doesn't light up at all, either there's an earthing problem to the globe, the globe has failed, or the wrong type of globe is in there.
As Ramrod mentioned, the parkers / Day Running Lights are a twin filament globe, 21W for DRLs, 5w for parking. Check your owners' manual for the correct type of globe and socket for that application. The globe socket base should have 2 stubby pins in it - one pin is for the 21W+ connection, the other is for the 5W + connection; the ground is common to both and via the metal outside of the globe base.
