Aston Martin LHD RHD Conversion (Lighting). The Aston Martin DB9, DBS, Vantage, Rapide and Vanquish “can all have their headlights adjusted for driving” in a country where driving is on the opposite side of the road, I will outline how to adjust the headlights but also show the limitations of this adjustment.
Aston Martin DB9, DBS and Vantage
These cars all have 4 headlights, with just the outer headlights operating on dipped beam, thus only the outer lights need adjusting to flat, note it is not possible to change to LHD from RHD or vice versa.
The lever should be down for RHD and up for Flat, the lever is between the projector bowls on the right hand light

and on the outside on the right hand side light

This how the conversion works, lens removed for clarity

DB9 Vantage projector set to flat, as can be seen this converts the beam pattern to flat, no kick up on either side, rather than LHD

Aston Martin DB9.2, Rapide and Vanquish 2
These cars have the single Bi-Xenon on each side of the car and have a very strange adjustment system.
