H.I.D conversion

The only change to the MOT in 2012 re headlamps is that if the main beam warning lamp on the dash does not illuminate when the headlamps are on main beam and does not go off when on dip beams are illuminated, the car will fail it's MOT.

For a new car to pass EU regs with HID headlamps, the car must have auto leveling to a particular spec and the headlamps again are to a particular spec.

UK type approval is no longer in place so there are no UK regs to make HID lamps illegal. A Department of Transport spokesperson has confimed this in a letter reproduced on another forum.

As long as the

Main beam warning light works re on and off.
The headlamps work and the aim and beam shape pass the test when viewed in the beam tester that the MOT VOSA regs require, your car will pass the MOT.

I think the relevant part of the regs is part (c) below from directive 2010/48/EU

4.1.4. Compliance with requirements
Visual inspection and by operation.
(a) Lamp, emitted colour, position or intensity not in accordance with the requirements ( a ).
(b) Products on lens or light source which obviously reduce light intensity or change emitted colour.
(c) Light source and lamp not compatible

The point is HID conversions should not pass the beam shape test.

My 06 Impressa has standard fit HID headlamps with headlight washers and self leveling and has passed two MOT as it should have.

The Department of Transport has said it has no plans to outlaw HID conversions.

There is no reason why a well engineered HID conversion will fail the beam shape test. Why should they not pass the beam shape test?

OTOH there is no proof that the available kits on sale will pass the MOT test.
