Hi
I have seen this on other forums and presume everyone is aware of the changes to the MoT effective from Jan 21, the advise below is from another site, apologies if everyone is already aware or it’s been subsequently updated
Please note that since January 2021, the MOT Inspection manual has been updated to include LED bulbs.
Section 4.1.4 now states the following:
“Existing halogen headlamp units should not be converted to be used with high intensity discharge (HID) or light emitting diode (LED) bulbs. If such a conversion has been done, you must fail the headlamp.”
This is a brand new update that seems to only focus on headlights.
There are no mentions to fail other LED bulbs such as brake lights, tail lights or reversing lights.
