Note to ATC Inspector:

The trailer should already at this point of inspection been measured for masses and dimensions. Record this dimensional data above as this may have a bearing on required lamps/reflectors to be fitted. Identify each kind of lamp and reflector evident on the trailer and complete the relevant section below. Some sections may not be applicable based on the trailers dimensions. Definitions at the bottom of this page help explain measuring location. The requirement for each lamp/reflector is contained in the green section of each table. On the left side of each table, record all the details of the e-mark and number and characteristic letter as on the lamp. The letter/character on the lamp identifies its function. The letter/character that identifies the function can be seen in the green section of table under “presence”. For example, the letters “AR” on the lamp indicates it has a reversing lamp function. The letter “L” on the lamp indicates its rear registration plate lamp function. Appendix at end of this inspection report has some illustrations that may aid inspection

Please use the remark section under each section if there is any comment/observation noted during inspection. If there are more devices fitted than space in report to complete the relevant information, please supplement report with separate document. Photograph all sides of trailer

Min height indicates distance from ground to lower edge of illuminated area, max height to top edge of illuminated areaWidth indicates distance from nearest external vertical edge of trailer to nearest edge of illuminated areaLength indicates distance from rear external edge of trailer to nearest edge of illuminated area on side lamps/reflectors or the distance between adjacent lamps.

Example of approval mark on rear lamp cluster

Above is an example of an approval mark on a lamp cluster. The letter “F” indicates Fog lamp function, “2a” indicates direction indicator function, “AR” indicates reversing lamp function, “R” indicates rear position lamp function, “S1” indicates stop lamp function. The two digits directly underneath each letter indicates the series of amendments it complies to. The “E9” in the circle is the country it was approved in. The number underneath E9 “1432” is the sequential approval number assigned by the country which approved
