MOT Problem :@

[That-Kid-O]

Bike failed an MOT today. Apparently the HID kit installed isn't alligned properly. The left is fine (beams off to the left) but the right side shouldnt beam off to the right but should be in a straight line...

And also the "beams are too high"

I looked on Google and found some info regarding taping the headlights to alter the beam pattern and put it through a re-test. Would this work? and if so someone help please

Hi

HID kits are not road legal.

Problem for the MOT is that the bit that emits the light can easily be in a different place to a conventional bulb, rendering the beam pattern pretty random (only takes the bulb to be a tiny bit out of position to screw things up), and tape isn't really going to fix that.

All the best

Just think of the oncoming traffic you've been blinding....

Hi

They probably will pass it with the lens taped up. However the beam pattern is due to the shape of the lens and reflector, so changing the bulb should make it dip another way.

All the best

LOL Ian I promise it doesn't blind oncoming traffic it is only a slight tilt in the beam to the right.

And Kickstart do I tape the headlights to "fix" the beam pattern or can I just tape the whole thing up?

[carvell]

You need to tape it up to fix the problem, not just tape the entire light up..

I've had an (import) bike pass an MOT with a bit of tape on the headlight to stop blinding the wrong people. You'll find that the tape will need to be cut into a triangle for best results.

Assuming they're your standard projector retro fits, can't you either rotate the whole unit, or dissasemble it then rotate the cutoff shield?

And to carvell...

Could you help me out on the taping technique? Or alternatively can't I just disconnect the ballast and tape up the whole right headlight so it isn't tested? or are there other problems to this? (high beam wouldnt be a prob as they are bi-xenon and act as both high/low beam)

[carvell]

I seem to recall form reading the MOT manual that only one headlight needs to actually function - have a look through the testers' manual:
https://www.transportoffice.gov.uk/crt/doitonline/bl/mottestingmanualsandguides/mottestingmanualsandguides.htm

With regards to taping it up, you need to point the headlight at a garage door and see where it's bright on the right hand side of the light. You then need to put some opaque tape on the light that covers this bright bit on the right.

Have a see if you can get away with disabling the light though.

Hi

From the link Carvell posted it looks like you could disconnect the dodgy aimed light on dipped beam. Claim it is only a main beam light. Tester might advise it isn't right but shouldn't be a failure.

All the best

Technically, no.

You may get some grief off the tester, but according to the manual it should pass.

I just have a single unit headlight on my imported ZX6R, the tester just taped the part of the lens up that allowed the kickup to the right, failed it first though

MOT due next month so will be taping it up again BEFORE it gets tested
