Are these night eye led h4 a direct replacement for the original halogen bulbs?

Still can’t get my hand in to take old one out? This post was so someone could advise if light unit has to come out to change main bulb?

I could be wrong but I’m sure changing your halogen bulbs for LED’s is now an mot fail?

That's what i was told that it was a fail because of the light beam it gave you had to have the proper light unit to project the light in the right pattern so as not to dazzle on coming vehicles
Unless these led bulbs can produce the same light pattern i think it has to do with the placement of the led on the bulb has to be in exactly the same place as a halogen would be to produce the same pattern
I could be wrong but there's that many led bulbs out there all claiming to be road legal it's a mine field i got caught out last year i bought some what i thought where road legal and it would of failed it's test a month later he just told me i would have to change them back to halogen and that they could of melted the wires i don't know how true that was but at least the led's were bright and you could see where you was going

I cannot sensibly advise on MOT rules other than to suggest that rather than guessing you talk to a testing station to confirm whether or not LED bulbs are explicitly banned for installation onto your vehicle or if the problem is simply that most LED bulbs do not provide an acceptable beam pattern when examined.

As for melted wires that can indeed be an issue so you will need a decent heat sink and fan to ensure the bulb does not overheat.

However the big issue with after market bulbs (so LED and HID) is ensuring the resulting light pattern reasonably matches the output from a halogen set-up rather than scattering light all over the show and blinding approaching drivers. Before spending your hard earned cash you may want to look at pertinent youtube videos from these folks. (I do not have any financial interest in them.)

As you will see they have real life tested and rejected hundreds of aftermarket bulbs and along the way identified the underlying design factors to look for and brands which actually match the beam pattern from a Halogen bulb when installed in a headlight housing only designed for use with halogen bulbs and therefore stand a chance of passing an MOT test inspection.

Do you know if the equipment level affects whether an error code is given on the dashboard?

Could h4r hid kit be a better option I’ve ran less and found them not to be that bright.

The current DVLA guidance to MOT testers says: ‘Existing halogen headlamp units on vehicles first used on or after 1 April 1986 must 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 for light source and lamp not compatible.

This does not refer to complete replacement headlamp units which may be constructed with HID or LED light sources.

If a complete headlamp unit has been replaced with a unit that was manufactured with HID or LED light sources, it must not be failed for ‘Light source and lamp not compatible’ but it must meet all other requirements detailed in section 4 of this manual specific to the type fitted at the time of test.’
