Thanks I taught it was something I could do myself

You can if you want. Plenty of instructions to be found online.

it'll probably fail again, after.

You can do it yourself using instruction from Youtube, but there are probably mechanics locally that have proper equipment to adjust them.

Its a 2 min job, get it done properly by someone who knows what theyre doing

It is. I've never paid to have it done.

It's a 2 minute job for someone with experience and equipment.
It's a 30 minute job for someone with experience but no equipment.
Or it's a 3 hour job for someone without experience nor equipment (but access to youtube, measuring tape and a flat drive + wall).

Did a car ever fail for having headlight aim too low ?

Seems to be, just point the light at the ground and good to go..

Equipment? What equipment do you need? Pull up to a wall on level ground and see is the offending light too high or too low, adjust as needed job done!!

To do it right is a bit more involved that that unless you roughly want to set it same height as other light.
It can be done 100 correct though without specialist equipment.

I find a dark brick wall is best as the joint lines in the brickwork can be a great help, I never had a fail yet... Will regret that won't I??

This equipment.


Then setting lights takes 2 minutes (assuming there's nothing stuck within adjustments mechanism).

If you want to to set your light correctly without equipment, it is very time consuming. As well as you need perfectly flat surface and ideally a flat wall (ideal 90 degrees to surface).

And yes - I know you can set in just by eye and test it on dark road, and very likely pass NCT. But that doesn't mean they'll be set correctly.


Remember that NCT allows your dipped lights to reach as far as 120m and as low as 30 metres, and very often if they are set lower they'd still pass as NCT guys don't bother.
This is a huge margin for error considering most car manufacturers give exact figure of how lights should be set (usually around 50-70 metres).
