Had HID in my Bird for 7 years, never an issue, adjusted correct always passed,
but May 2018 the usual garage told me, things changed in March 2018, HID conversion is now a MOT fail, we will pass it now but you will have to sort it for next year, I then asked about the LED I have in the high beam, told that's not a problem, just HID?
so went on GOV MOT manuals website and he's right,
so it looks like swap the HID bulb for MOT in May, then back
MOT manuals section 4 -
"Some motorcycles may be fitted with high intensity discharge (HID) headlamps. Existing halogen headlamp units shouldn’t be converted to be used with HID bulbs. If such a conversion has been done, you must fail the headlamp."
