E marking guide
The standard for automotive bulbs is ECE Regulation 37, more commonly shortened to the ‘E’ mark. ECE Regulation 37 details exact specifications that cover the light output, fila-ment geometry, voltage and wattage and the size and shape of the bulb.
The light output specification ensures the correct level of illumination from the
light assembly. Too bright and you could dazzle other road users. Too dim and you may simply not be able to see the way ahead.
Filament geometry specification ensures the correct alignment of the light source,
(the filament, in the light assembly) ensuring the light source is correctly focused for optimum light output.
Voltage and wattage specification ensures that the bulb can safely be fitted to a
vehicle’s electrical system without overloading the switching or wiring harnesses.
Size and shape specification ensures that the bulb fits correctly into a light unit or
assembly.
What makes a compliant bulb?
A compliant bulb will always have....
The above approval mark affixed to a filament lamp indicates that the lamp has been ap-
proved in the United Kingdom (E11) under the approval code A1.
The first character indicates that the approval was granted in accordance with the require-ments of ECE Regulation No.37 as amended
by the 02 & 03*/series of amendments.

The E mark is only one part of the specification and even
if the product appears to be correctly marked it may not meet the standards.
Ring Automotive has full facilities to test ECE Regulation 37, including:
1. Overall light output and colour temperature in it’s integrated sphere Photometer 2. Voltage and wattage 3. Geometry via shadow graph 4. Physical dimensions 5. Beam pattern in a 10m dark room using the latest image capturing technology
detecting over 1 million light readings per test.

Beyond E marking
The E mark is not always a guarantee of quality, the performance of the bulb is the real test. Ring Automotive has identified many supposedly approved bulbs as being counterfeit. These are simply poor copies of genuine bulbs. That’s why Ring Automotive has invested in its own quality assurance laboratories here in the
UK. No other bulb supplier has made the investment nor has the range of equipment at its disposal.
