MG MG Y Type - prefocus LED Bulbs
| Hi All, Classic dynamo has now in stock LED headlight bulbs to replace standard prefocus bulbs, NOTE these LED bulbs are NOT suitable for the lucas 700 tripod units that have the shield behind the tripod. John UMG624 |

| Hello John What are their contact details please? Kind regards Anton |

| I have ordered P36d BPF Positive earth FBIA which I think is correct for the standard Y Front lamp fitting http://www.dynamoregulatorconversions.com Peter |

| Hi John I have installed LED bulbs on my 1929 Morris Oxford and 1934 Morris 10/4; I can now confidently drive at night and even see where I am going!! No worries about the battery discharging at night. The festoon bulbs on the semaphores are fantastic and are really bright and flash like modern trafficators.Following traffic now seem to understand which direction I intend turning. "Unfortunately" on my MG YT, I have sealed beam headlights and will have to change the total light fitting to be able to install LED lights. Probably not worth doing if the new 45 amp alternators is the price stated in the Bulletin. Neil Cairn's article in this month's MGOCC Bulletin is excellent and I intend converting the rear 'D' lights according to the procedure he describes in the article. Best wishes Anil Koshti |

| Anil, you might want to contact your insurance company if you fit a dynamo type alternator. My company stated that if the car had an electrical fire it would not be covered. As the alternator' kicks our significantly more amps than a dynamo. |

| Thank you all, for your valuable inputs. Much appreciated :o) Anton, Y/T 4220 |
| Anton Piller |
| C Callaghan's comment is very interesting. It would be useful if other members who have carried out this modification could inform us of how they progressed with the insurance aspects. Anil YT |

| Has anyone fitted these headlamp LEDs. If so I would be interested to know how you got on. I have just sent mine back, I found that the movement between full beam and dipped beam was much to much which meant the dip was too low and the main was too high. I was told that this problem had not come up previously. Pity because it was a really bright white light and didn't move the ammeter. Peter |

| I also bought a pair of LED BPF from this company and have had the same experience as Peter V. the beam pattern was too high on main and far too low on dip. When I spoke to the company I was told "that they'd never had this problem reported to them before". When I mentioned Peter V.'s experience I was told it must be a Y type problem! when I checked a std. BPF against the LED version, the two light sources are approx. 3mm deeper into the reflector. When I rigged up a 3mm spacer ring between the LED and reflector, the beam pattern improved confirming my suspicion, although the connector could not be fitted. I am dissapointed and have sent mine back. Dave |

| Good to hear it was not me at fault Dave but still disappointed as the light quality was excellent. I thought our headlamps were pretty standard as they are on T Types as well. Had another great weekend at Llanerchindda last week. Peter |

| Hi All, Just been talking to Peter who does the LED headlight bulbs there was a problem with the bulbs in the y reflector but he has found the problem with one of the LEDs being in the wrong position for those reflectors, he will have a new batch in about 6weeks time which should cure the problem. John UMG624 |

| Hi All, These photos might be of interest if you are thinking of going down the LED road. They show the very white LED against the Prefocus light.With prefocus only one filament is on at a time, with leds on dip only one led lights up when you go to high beam the low beam led is supplemented by the high beam led resulting in a really good light output. the downside of these LEDs is the necessity to carry a magnifying glass with you to be able to see the slight movement of the ammeter when you switch the headlights on !!.The the black and red crosses were part of a test the red being LEDs you can see the distance between high and low compared with the prefocus black crosses, this has been sorted and the modifyed LEDs will be around in six weeks or so.

| John, Where are the photo's is there link missing? Richard |

| Richard i dont know !! |

| John, The photo has size limit, I gues if it's not below the limit the post won't attach Richard |

| richard its telling me successful upload so there are 3 go's out there in the void!! |
| JC Jebb |
| Hi All I am not sure why no photos,will try to workout where they are, Sorry about this john UMG624 |
| JC Jebb |
| Another difference with an led head light set up is when the lights dip they go straight down, the standard bulbs dip to the left in the UK. If you set the main beam straight forward and parallel to the ground as recommended in the manual the dip beam might be still be tending towards on coming traffic. To alleviate this problem, the instructions that come with the Led bulbs say, very careful setting is required with on road testing. Peter |

still trying to put photos on here??

| JC Jebb |
| Hi All I got there in the end!! 
|
| JC Jebb |
| hi Picture 2 is LEDs in dip position,no3 is normal prefocus bulbs look at the difference plus the ammeter pointer well up the scale John UMG624 
|
| JC Jebb |
| I did an almost identical test on a board about 1 meter away and got the same results. the difference on the road was huge. You can see how the standard bulbs dip to the left. Peter |
| P W Vielvoye |
| Hi Peter, I will have a word wih Peter tomorrow about trying to get the LED bulbs dip position over a little bit more. John UMG624 |
| JC Jebb |
| Hi Peter, Had thet word and they are going try to to get dip/main in the same positions as prefocus bulbs.I think part of the idea of LED dip/main above each other was a universal light for left and righthand vehicles,anyway we will see what turns up in a few weeks time. John UMG624 |
| JC Jebb |
| John,If he can get it right it will be well worth the investment. I will let you try them out next time so keep us informed. Peter |
| P W Vielvoye |
| John, I’ve been testing my modified version of the BPF bulb and now have an excellent “as original” beam with high beam just above low beam. The dilemma I am now up against is this: everyone else is fine with centre dip. You and your Y Type club boys say you would like to see a dip to the left. This is possible, I have modified another test BPF to dip to the left successfully. BUT…….if I do a left hand dip this will be fine for countries that drive on the left – UK, OZ basically. I will also have to do a straight or right hand dip for the USA, Europe and other countries that drive on the right. A universal centre dip bulb would suit right or left hand drive countries. So, my ultimate question is – Will a centre dip be fine for you and the other Y Types if it has a perfect high beam slightly above dipped beam or do you really need a lefthand dip. Hi All, Can we have a little vote on wether centre dip would be ok for you or MUST you have n/side dipping?. I have just checked my modern!! Sierra and the dip is straight ahead and mainbeam ia actually slightly to the n/side would you believe it.Anyone who has already bought the LED bulbs with the wide main/dip pattern will get replacements by sending them back once the new LEDs show up in the online shop.

| hi all, Classic Dynamo & Regulator Conversions now have the reworked LED Prefocus bulbs in stock. John UMG624 |
| JC Jebb |
| Let us know when you have tested the dip angle John I lost my postage sending back the last set that were way out. Peter |
| P W Vielvoye |
| Hi All, Been talking to the owner of Classic Dynamo who produce the LED prefocus bulbs and he assures me the problem with the beam pattern is cured and i take his word for that. If anyone has the early faulty bulbs if they send them back with a covering note they will be replaced by Classic Dynamo free of charge.These new bulbs are already half sold out so don't hang around if you are a person with the faulty bulbs. John UMG624 |
| JC Jebb |
| Which beam pattern is OK now? is it the universal centre dip bulb that would suit right or left hand drive countries - or is it just a left hand dip for UK and OZ? Anton |
| Anton Piller |
| Anton the New bulbs are universal, centre dip usable in left or righthand countries. John UMG624 |
| JC Jebb |
| Thank you, John. I am a bit late with my reply, but anyhow.... I am going to order a set of the new universal LEDs today, but will not be able to test them for quite some time. Anton |
