how do you go about swapping the std fit aux lamps for some decent after market ones like the cibie mini oscars?

can the old lights simply be taken off & the new ones mounted in their place on the existing brackets?
electrically is it as simple as unscrewing the earth wire off the old lamps & screwing into the new ones?

In short, yes.

Most lights ground through the light housing. If you're new lights only have a single wire then it's for power. The ground wire from the harness can be attach to the bracket to make sure you get a good ground.
