Thanks IanB.
Yep, my 5th Gen 4Runner SR5 has Projector Low Beam Headlights, but no Left/Right adjustment screw.
As you say, Toyota don't sell the 4Runner in any Right Hand Drive countries so there are no replacement headlight units available.
The Up/Down adjustment isn't satisfying the UK Department of Transportation as still too much glare up and to the right.
I've been battling with this issue for 3 months now and struggling to find a solution. Guess I should have done more research before shipping the vehicle, but it's here now and I need advice, however radical!
My workshop guy is offering to cut the headlight units open from the rear and fit a baffle to shade the up and to the right glare. This seems like a last resort option to me!!
