Here I ‘d like to post a UK native who talked about the E-MARK , very interesting and informative：
E marks on lights. Whats that all about then? I can give you the short potted version that you need to know, followed by the
longer version for those with a high boredom threshold.
The “E” means Europe. Hence American lights are not usually “E” marked. (The fact that they exceed ours for safety in most
regards cuts no ice with Brussels.)
The short version: If a light has an “E” mark on it, it means it has supposedly been approved – somewhere in the EU as
compliant with the myriad of bullshit European regulations applicable to such things.
Chances are, if your light has an E mark, your VOSA tester will not get too involved seeing if it complies to some obscure
Brussels rule he will merely assume it does because it has an E mark. That said, he reserves the right to check something
himself if he is not happy with it. My experience suggests they look for an E mark, and when they find it, they say, “Ahh,
thats OK then”.
That is not to say that your non E marked American light is not compliant with the rules. It might well be, but he is more likely
to check it with light meters and tape measures, etc. if it doesn’t have an E mark.
We are referring here to VOSA testers though. MOT testers seldom have the knowledge or the inclination to get involved in the
minor detail of EU regulations and associated Euro babble. I tend to E number the car up for SVA test, and then fit what I want
to fit straight after (if it differs).
Below is some Euro babble about light bulbs. If you can struggle through it, you can see why I gave you the potted version above.
An E-mark guarantees an automotive product complies with European vehicle legislation. In the UK, national
implementation of Construction and Use Regulation 95/54/EC has made it a criminal offense to use a car with a non-E-marked
part fitted.The automotive bulb market is covered by Regulation No. 37, revision 4, defining which bulbs necessitate an E-mark.
In general,bulbs that are fitted in external positions on a vehicle must abide by this legislation, although some interior lamps, for
example those used in the courtesy lights on the vehicle doors, also require approval.
Furthermore any lamp unit that is E-marked must have E-marked bulbs fitted. The number accompanying the E-mark is not an
indication of the quality of the product, a common misconception, but indicates the country in which the testing took place. All
countries test the bulbs in the same way against the same standards, ensuring uniformity of the bulbs. Consequently no individual
E number can be associated with any superiority in quality.
E1 Germany, E2 France, E3 Italy, E4 The Netherlands, E6 Belgium, E9 Spain, E11 United Kingdom, E13 Luxembourg,
E18 Denmark, E21 Portugal, E23 Greece, E24 Ireland, etc. The main checks performed to assess E-mark applicability for bulbs
- Dimensional checks ensure a tolerant lamps beam pattern
- Electrical checks certify that the power of the lamp does not exceed the rated value
- The brightness of the bulb, rated in Lumens, is appraised by photometer inspection
- Color temperature tests check that the color of the light emitted from the bulb is predominantly white.
It is important to note that life cycle is not part of E-mark testing and therefore differs greatly between manufacturers. It is
essential to pick a well-respected brand in order to assert confidence in the longevity of the bulbs.
A legitimate E-marked bulb will have numerous details stamped upon it. These include the E-number followed by a 3 digit
approval code unique to the manufacturer and product. The trade mark or brand name should also be issued, along with the
rated volts, watts and the letter U if the lamps UV output is tolerable. If the bulb does not possess these stamps, there is a good
chance the E-mark is not legitimate.
