2005 is too late to register a US import with just an MoT test, it will have to undergo a full IVA inspection.
For a tidy job on a TJ you will need to get:
2 E marked RHD 7" headlamp units with sidelights. (For obvious reasons)
2 Europe spec wing repeater lenses. (They stick out because they have to be visible from behind)
2 Europe spec tail light clusters. (because you need orange rear indicators)
1 rear fog lamp and switch with illuminated telltale. (you have to have one)
1 number plate lamp. (Because the Euro tail lamps don't have one built in)
You will have to:
Disconnect the amber running light wires and use them for your new white sidelights.
Fit the new headlamps, wire in the sidelights and set the alignment properly.
Fit the Euro spec repeater lenses, you can rewire so they dont come on except when indicating but it isn't strictly necessary.
Fit the rear fog lamp to the offside and wire in.
Fit the European tail lamps, rewire the brake lights to work independantly of the indicators.
Fit the number plate lamp.
Everything else should comply, For IVA purposes, DOT and SAE markings are acceptable for things like tyres which normally have to be E marked.
