Daytime Running Lights

[Fazman]

Hi all , just wondered if someone can help. I havre a 2016 T6 with the horrrible yellow daytime running lights i recently bought 2 led error free bulbs off a seller on eBay . I fitted them both and only one worked so contacted the seller and true to his word he sent me another one which arrived today and again only 1 works so i took the working bulb out and tried it in the other light and it worked so left it there and fitted the third bulb to the other ex working side and it doesn’t work. So i refitted the yellow type bulbs and both work . Can anyone help , is this due to the type of bulb as i am stumped as to why this happened

Thanks in advance

Swap the wires over in the bulb holder, it’s just a polarity issue

Both wires are grey as halogen lamps aren’t concerned with polarity, it seems pot luck which way they are connected at factory
