mot fail

Hi & welcome.
What is the make & model of your car please.

There must be at least one sidelight on each side. I'm not familiar with your model but going by that failure your vehicle must fitted with more than one? If this is the case then at least 50% of your sidelights must be working on each side. For example, if you have two on each side then only one needs to work. If you have three, then you need two working.

Have you tried turning on your sidelights and having a look at the rear lights?

Hi ratty. yes. position lamps are the rear tail lights and front side lights. is this the arrangement of the rear lights on your car.

Have a look at this link to a porsche forum, it might help.

Thanks for this but it doesn't tell you how to take the horn pad off and knowing my luck I will probably break it
Thanks

Jock, is there a difference?

Say a vehicle had LED rear position lamps and in that cluster there were 12 LEDs, thus 8 were inoperative (clearly visible), that equates to more than 50% inoperative, so I assume you would agree with that.

What if then like the Ford Mondeo rear lamp clusters you have 3 position lamp bulbs fitted to each side cluster, if two of three bulbs were not working, i.e. 66% inoperative, should that pass the test?

I am not picking holes in your post Jock so please don't read into it in a bad way, it just reads to me as though you are saying the 50% rule does not apply to single multiple bulbs, but only like LED fitments type of lights?

You said;

Less than 50% of light sources working is for when a single lamp is made up of many individual light sources not for when there is more than one lamp per side.

Can you see what I am referring to?

ratty. according to what i have now read the horn push pulls off starting at bottom and slowly work around to the top, it can be a tight fit. if the steering wheel is the same as a 944 then here is a link to a complete workshop manual for that model which could help.
