many new style car lights are 'flat dip' ie they have no kick up to the left, much like motorbike lights thus enabling manufactures to use the same lights be the car left or right hand drive.
The current MOT Inspection Manual has two different sets of criteria: "British American type" and "European type".
I haven't heard of any problems with testing. (But the wording is tortuous.)
no problem at all for the MOT with flat dip
Just for Jonathan (and of course others who are interested...) below are some amateur pics of the Dave Gemzoe LED's per John's post #4.
It wasn't dark at the time nor a scientific test but more of an "alignment aid" process - however you can see how brighter they are and how well they cut-off on dipped beam (similar pattern to the original H4 bulbs) to avoid glare to on-coming vehicles. At night they are much more impressive
That's encouraging! Did you have to adjust the bulb alignment at all?
John - no adjustment at all but that was why i put the tape on the sheet to check the alignment when fitting .... just "plug & play"
Thanks for that, Neil. I'll see what happens when I fit my own Gemzoe bulbs in a few weeks.
Garf - out of interest what size headlights and what type of lenses are you using?
Ian - 7" with the original reflectors and lenses from 1995 (with a quick polish inside).
I should add that the non-LED was also a Phillip's Extreme 140% bulb ....so even more impressive! You can actually rotate the LED bulb in its plastic holder (which itself slots perfectly into the reflector housing) in case you need to adjust get the horizontal alignment (there are placement notches as you rotate but I didn't need to).
