In the case of a HID kit, a ballast or ignitor?

So, this means any vehicle from the old B/C reg will automatically fail if it has a conversion done (by conversion, I mean just the bulbs replaced).

Can't see much changing in the real world, plenty of people know a 'friendly' MOT tester and once they are in, unlikely to be stopped by the Police, unless they are going to target cars with wrong coloured bulbs or that seem excessively bright (unlikely)

HiDs are easy. They have a warm up.
LEDs are instant. If you know what to look for its obvious (even before looking at colour temps).

You don't even need to know the build sheet details. The outer lens tells you what it should have.

Not much changed then other than cars used before 1st April 1986 are exempt.

And see what ?
What they ^^^ said.
And HID kits will have wires going through the cover over the back of the converted bulb .... that's what the converted Smart 451 had when I first bought it

How , no method notes , everyone is guessing at this point , yes HID is much more obvious but some LED that just fit in the housing behind a thick projector lense more tricky .

It's like the DPF MOT test , you have to know the ins and outs to get a complete understanding rather than saying.. = instant fail .

As I've said. Colour temp is a giveaway as is time to full brightness. HiD are very slow, halagen are faster and LED instant.

But we don't know what exactly they are looking for , so it's all guesses at this point.


Fail or pass ?
