Hi to all
My car is a 2006 Plus 4
I am sure this has been addressed and perhaps all I need is pointing to the relevant thread.
I want to convert my standard Morgan bullet wing mounted side lights to MOT compliant DLRL LEDs
I believe that the standard bullet light bulb can be converted to (I think) a six ish LED cluster bulb.
I also know that the existing live wire will need to be connected to an appropriate ignition on permanent live.
However, to be MOT compliant I want to ensure the DLRL are dimmed when the main/dipped beam is manually switch on. So I am assuming there is a gizmo/relay that senses/knows when power is going to main/dipped beam and consequently reduces voltage to DLRL bulbs.

Your comments surprise me. All you are going is using your side lights as a sort of DLRL, and you are allowed to run with sidelights on all the time anyway. I am sure there is no requirement for sidelights to dim when the headlights are on. As I understand it, the only difference with DLRL is that on modern cars they are designed in such a way that they cant be switched off. That rule doesnt affect you or you would have a car fitted with DLRL anyway.
You may enjoy / want the added complication of dimming as a bit of tinkering / a project, but IMO you dont need to do it for MoT purposes. Bestc check, or if you have already checked tell me I am talking nonsense.
I was told that if you are using the high intensity LED as DRL (as per new cars) they must dim when you put your head lights on. Its NOT just about having permanent side lights on.
I also have a friend who has converted his bullet lights to bright LEDs (without auto dimmer) and he is being flashed by on coming cars at night time. He is now trying to modify to dim (to half intensity) when headlights on..
The bulbs he used required a modification to bulb holder/bracket - which I am trying to avoid. Hence trying to locate a bright DRL LED bulb that fits existing bulb holder within bullet housing. Needless to say the LEDs need to be forward facing.
I am positive that with high intensity DRL they must dim to be MOT compliant.
Just found this on Govt web site:https://www.gov.uk/government/publications/daytime-running-lights/daytime-running-lights
Legislation and requirements:Vehicle manufacturers must fit DRL to new types of passenger car and light goods vehicle (car derived vans) type approved to European vehicle requirements from February 20111 . In practice this means that any new model launched after this date, and many launched before, will be fitted with DRL. However, existing models on sale before this date without DRL fitted can continue to be sold and used indefinitely.
Similar requirements apply to large vehicles (such as HGVs) and buses from 7 August 2012. Motorcycles do not currently require DRL to be fitted, but most manufacturers voluntarily opt for an AHO (Automatic Headlight On) system to be installed as an alternative. Changes to European legislation will, in future permit manufacturers to fit DRL on their motorcycles.
DRL activate automatically when the engine is started and remain on unless the headlamps are switched on. They may however remain off in some low speed and stationary situations. In general all other lights should remain off when the DRL are on but for a limited period some vehicles may be available which automatically activate the rear position lamps at the same time as the DRL.
DRL may be combined with other lamps. For example some manufacturers use the same lamp for both the DRL and position lamp.
In these cases the DRL automatically dims to function as a lower intensity position lamp when the headlamps are turned on. DRL placed close to direction indicators may also automatically dim when the direction indicator is active. This is to ensure that the direction indicator is not masked by the light from the DRL.
