I may be wrong but I thought lamp housings were marked if they were hid. Googling suggests they'll be marked DC for hid dipped, DR for hid main, DCR for both. Presumably lack of these markings would be enough to confirm any suspicions and cause someone to poke around a bit more for a HIDS4U logo on the ballast or similar.
Edit - these markings are in fact one of the things referenced in the testing manual regarding how to identify hids. Lack of them could raise suspicion. How bothered your average tester will be in looking for this stuff is a different matter.
I sincerely hope you had to Google thatOn the Corsa C it's on the sticker on the back of the unit
Not guy probably not checked the memo lolMy friend has a HID kit fitted to his 2010 Focus. It just went through its MOT no issues.
