Good morning all, as promised in a previous post I would put up the two headlight beams which are applicable for asymmetrical and symmetrical pattern, hope I have attached them properly as its been an age since I did that, you will see clearly the background is identical on both, with the asymmetrical pattern showing clearly the kick up section which appears common on most new vehicles, with regard to the Defender the beam pattern will believe will be symmetrical due to its reflector shape being originally the quadoptic design plus the led also a symmetrical design. The test im going to carry out should show the beam pattern of the led beam being flat topped ( A quick check confirmed that)
I had a lovely PM yesterday from Lord Haggis which was very helpful, thank you very much J, briefly in the post the lovely member advised he has had no problems getting his trucklite through the dreaded MOT with them fitted. I than decided after studying the lens he posted of the trucklite (see in earlier post) to study the details they provide and yes the sales patter says UK street legal etc, then it struck me!!! It you study the writing on the lens the verification country ain't the UK E11, but in fact Luxembourg E13, this in fact confirms the information I read where It stated, it matters not where the verification is carried out as they are all supposed to be working from the same hymn sheet. Thats my challenge today complete, now to get on with the cover of the beam tested i have been putting together, weather and time permitting, im hoping to get some sense from the test before I run out of time, I'm due in hospital very soon to have a new set of bushes fitted to my knees,, fingers crossed they are not cheap Chinese copies? 
Please advise if the patterns do not appear, will have another attempt !!! Regards to all Ole Dave Last edited by OleDave on 20th Oct 2022 11:14am. Edited 1 time in total |

Looking forward to the next pics of the actual beams from the LEDs  |

Standard Defender Quadoptic halogen lights have the kick to the nearside, not a flat beam.

Click image to enlarge Hi all, sorry its been a while continuing with the test of these SP headlights but the weather has been appalling so any test was out of the question. I am now able to put a picture of the shape of the SP LED headlight beam but please take no notice of the relationship of the pattern to the scales marked on the board as the board was not set up as only a beam shape was required. When the rain did stop I spent hours setting up and resetting the board to adjust the beam so that the peak would be under the 1.25% mark, a number of problems arose which meant it impossible to obtain a meaningful reading, the initial problem was I ran out of adjustment on the headlight setting screws before I could get below the 1.25 figure, the other problem was I could not get a repeatable pattern, if I moved the vehicle the readings on the board didn't match again, there could be a number of reasons for that which includes the surface I was testing on which I could not guarantee was perfectly flat and level and without low points, after much head scratching the decision was to taken to go the ultimate route and get the landy into the garage and tested on their beam setting machine, im hoping to get that done early next week so will advise the results following that. Finally for interest I took the landy yesterday up a local dark lane just to see what the beam looked like, I found it to be a white with a blueish tint, what also was noticeable and maybe it was my eyes the beams seem splattered with darker spots? Its certainly not a solid concentrated beam from what I saw, this could simple be explained by the old saying You only get what you pay for! Unfortunately I am unable to compare the SP led headlights with a more expensive set such as Trucklite to see their beam patterns. Thats it for the moment folks, hope to have something more positive next week. Regards Ole Dave
Certainly not a solid what I expected? |

Interesting, not exactly flat, is it. I don't know if the lack of flatness is sufficient grounds for failing the MoT beam alignment test.

Hi Blackwolf, as you say it can hardly be called flat and I agree at this moment im not sure if that's a failure? Will know a bit more on Tuesday after its been checked and I've had a quick chat with the inspector, I don't think I will be able to discuss it in any depth as I know they are very busy and won't be able to spend the time.
I just have this suspicion that its going to be down to "We always do it this way, as we have been taught" Regardless of the fact that vosa clearly states not all beam are flat! But we will see? Ole Dave |

Thanks for the pic dave.
certainly a different shape to what you would expect from a conventional unit. Rather unhelpful having a bump in the middle of the pattern as by the time the 'bump' is low enough to be legal, then you'll be losing quite a bit of light on the nearside where you would normally have it. Unlikely to cause any issues with traffic coming the other way though. If I get the opportunity, I'll run the pic past my MOT guy and see if he has anything useful to add. Presume this was the dipped beam? How does the main beam pattern look? - If the dip beam is legal, then I'm still tempted to try a set on one of my cars. |

Hi everyone, as promised i would update this thread following the results of Mondays ultimate test of the SP LED headlights with a VOSA MOT inspector at the garage on their beam testing equipment, finally I think following that test I can bring this topic to a conclusion as I have the results.
The Defender was on the beam tester at 8.45 Monday morning, before the test began I explained to the MOT inspector who I know well as a no nonsense inspector, the background of what I was aiming to achieve with the LED headlights plus the fact that I had studied the rules and regulations and requirements of VOSA for headlight legality. Unfortunately on this occasion I could not spend as much time as I had hoped asking questions and possibly taking pictures of the results as vehicles were being lined up for their MOT test as mine began, from personal experience I knew the opinion of this vosa tester would be the deciding factor on the SP led headlights no matter what the outcome was, The first headlamp to be be tested was the offside, as it turned out my time spent making up a test board proved that I was fairly close when the beam was projected into the tester, however, to get the beam down below the 1.25% mark proved to be a bit of a challenge as the bottom adjuster ran out of movement before the beam got to the required 1.25% mark so further adjustments had to be made equally to the left and right adjusters to drop the beam to the legally required mark. The beam on the test machine showed up to my surprise as a much better flat top than on my test board and the three dip beam LED lenses making up the beam pattern converged nicely into a uniform flat top pattern with no kick up witnessed, the opinion of the VOSA tester was that the beam pattern met the requirements and would in fact get a pass for the MOT. Next the nearside headlight was lined up to the beam tester, again it was close but not close enough and the same problems were experienced in getting the beam down to the 1.25% pass line as experienced on the offside, eventually that was achieved by again screwing out the two side adjustments. The beam pattern again was a flat top with no kick up evident, what was evident and as the tester explained, it seemed a messy pattern compared with the offside in that the pattern didn't converge correctly, that could easily be seen looking into the beam tester screen, the opinion here was it was possible it could be a fault in assembly or even possibly an led emitter was out? Unfortunately its a sealed unit which makes it impossible to see what might be causing the uneven pattern, in conclusion and although it would pass the MOT inspection as legal it would under the current MOT guidelines have to be issued with an advisory note as being an uneven pattern. So in conclusion, the SP headlights can pass the MOT test and be legal to use, however, the same cannot be confirmed for any other make of which there is an endless choice. Finally I am of a mind to contact SP to see if they be open to exchanging the one headlight which emits the uneven pattern for a replacement unit, wether they will or not is debatable? Well thats about it for the moment, I hope this process will be of assistance to other on the fab forum, finally if you have any questions regarding all of this please do not hesitate to contact me and I will do my best to answer your queries.
