The only garage this might be an issue is an opc or specialist. Mainstream MOT are big business. They have neither time nor interest to worry about dismantling headlight assemblies to confirm compliance. Never going to be a real world issue.


My T-light hid equipped 993 sailed through the MOT today.
As other posters have said, you'd have to be an inquisitive expert to discover the HIDs where not original.

Thanks - my 993 with HIDs has likewise passed all its MOTs ok since 2010 .... the issue is new Dft guidelines wef 18 May 2018 (they are available online) state clearly that aftermarket fitted HID lights will be failed.

FYI Section 4.1.4 on page 7 states:

Some vehicles may be fitted with High Intensity Discharge (HID) headlamps. It is not permitted to convert existing halogen headlamp units for use with HID bulbs. If it is clear that such a conversion has been carried out, rather than replacing the entire unit with one designed and approved for use with HID bulbs, the headlamp should be rejected.

I'm not sure my MOT station would even ask the question, given the scant attention they pay to headlight alignment.

For the first couple of years I owned this car one of the headlights was obviously misaligned because I had a great view of the road when the headlights were dipped but people coming the other way kept flashing me because they thought I had the headlights on beam.

I eventually set about trying to adjust them, but moved them too far in the other direction to such an extent that we couldn't drive the car at night because the headlights were pointing straight down at the ground.

The car has probably passed five MOT's during this period, with the headlights completely misaligned, so I have no idea what checks they are doing, but there is obviously quite a margin for error. On that basis I'm reckoning that checking the internals is probably way beyond them.

For what it’s worth my old man is an MOT tester; says there is next to no chance testers will be investigating the nature of the lights, presence of a ballast, etc.

Once checked for aim they are pretty much done.

Doesn't surprise me, I asked them about fitting HID's for me a few weeks back and they declined saying it would be an MOT fail. I'm still tempted though and then get an MOT at a non Porsche specialist.

Yeah, I think I'll go visit my Local Garage for the MOT..

Hi,

My 993 has the Tore B kit and went through its MOT about three weeks ago with my local OPC and there we no comments what so ever. Just goes to show its another of life's mysteries.

Admittedly I've not fitted HIDs to a 993, but it's a piece of cake on a 987 Cayman, you could swap them out come MOT day in 20 mins.

I couldn't remember when it was - so I just checked.
I fitted Tore's HID kit to my 1st 993 in 2013, and my current 993 in 2014 - so that's now passed the last 5 MOT's without an issue.
I don't use OPC though.....

My 993 passed it's MOT with HID headlights with no issue at a OPC. However a week after, my Racing Puma failed with HID bulbs at a Mr Clutch. Both headlights are projector and perfectly suited to a HID bulb. I guess the difference being that no Puma was offered with xenon headlights and thus obvious that they were aftermarket. With a 993 it wouldn't be so immediately obvious. As Tore states the basic headlight design is identical. No self levelling, though I guess most had headlight wash.

We have a Clio V6 in the family with standard fit gas discharge HID headlights. It has no self levelling as standard as the back of the car is never going to be loaded enough to push the headlight aim up. I suppose that same notion applies to some 911's - no rear seats, no effect on headlight aim. Any weight in the boot is going to push the headlights down which is not going to present a problem for other road users.

Never had a problem with my Hids at MoT time. No washers, no auto levelling. I have Morimoto projectors with Tore B's hid kit, mains are Cyclops Leds ( a bit of trimming of plastic required) it's all internal to the pod and looks std except when you hit full beam. The Morimotos have a very sharp cut off and are really bright just below that so adjustment has to be spot on.
