2010 Discovery 4 high beam reference lock (or lumens)
Hi,
Can anyone please tell me what is Disco 4 high beam reference number. Units are of that type: AH22-13W029-MD
The reference number should usually be on the headlight unit, but it isn't . I have searched the interwebs for hours and even asked from the LR reseller here. No luck.
I want to add extra lights, but the sum of high beam lights can't be more than 300000 cd (or reference number 100).

So as it seems, even Land Rover themselves don't know about their product. TBH it was kind of embarrassing to say, that the local dealer doesn't have the information. But telling them that LR themselves ..Don't know either to or
Help me Obi-wan Kenobis. You are my only hope.
Thank you for contacting the Customer Experience Centre.
After speaking with another team within the department they believe the light fittings may have been changed previously which is to why you cannot locate the reference number.
Unfortunately we do not keep any records here to look into this further.
We also as a manufacturer would not recommend amending the vehicles original specification.
I am sorry this may have not been the answer you were looking for.

I have never heard of a European rule that states the maximum candle power of main beam vehicle lights. There is definitely not an Australian one, only a maximum number of additional main beam lights.
Have you been able to find the ‘main beam reference’ number of the extra lights that you plan to fit?
Is this something that the Estonian authorities actually check?MY14 TDV6

In Finland, if the original high beams are unmarked, the reference value is assumed to be 20 (I think). The sum of reference values cannot exceed 100 in the front here. Perhaps you could take a look at Estonian traffic regulations whether the same applies over there?

nelivedu the article you refer to is incorrect.
The maximum permitted light output is 430,000 cd which is equivalent to a total of 100 of peak beam reference number. The maximum used peak beam reference number used to be 75 which would be equivalent of ca. 300,000. The change in maximum peak beam reference number from 75 to 100 took place about a decade ago.
You can check these figures out in UNECE R 48 section 6.1.9.1
Now the D4 headlight cluster would need approval markings for low/main beam, DRL, indicator etc marked on it which would be a lot of information on the front lens. The chances are that the approval markings will be on the back of the main housing rather than on the front lens.
The UNECE regulations apply through out Europe and in signature and participating countries.

In our law it's marked 300000cd = ref.100. Anyway, this does not matter much, because they are looking for the reference number anyway (not the candles or lumens) And Kelvo, yes they are pretty strict here with the MOT stuff. I guess we are bit of a German "Ordnung muss sein" wannabes.
Lights I bought are LuminaLights Predator x2. They are ref. 30 each.
I wish they would assume that unmarked lights are 20. Then it would be all honky dory, however the mot guy I asked, said, that he will have to fail me, because if he can't locate the ref. marking he does not know if its below 100. I know in Finland they are more lax about the extra lights. Probably because swedes drive around like x-mas trees (Just jealous .

Funny - I’ve always considered Finnish inspections and police to be not-so-lax compared with UK and US. In ‘murica almost anything seems to be legal.

I find that hard to believe. Estonia is a signatory country to the UNECE and a member of the EU. The EU is a participating party to the UNECE regulations. These regulations are for Vehicle Harmonisation so that the regulations are standardised between different countries. I can not see how a country taking part in the UNECE regulations can redefine the standards as that would make it difficult to harmonise vehicle standards.

Only information I can find on the lights is this sticker. Doesn't seem to have this reference lock number somewhere though.

Isn’t there anywhere the letter E in a ring and numbers/letters to the left or right of it? I thought all E approved kit had to have it stamped somewhere...

They should indeed. But haven't found it anywhere. Looked all the pictures on internet too. Mystery!
