Welsh 320d Posted January 3, 2018 Report Share Posted January 3, 2018 Hi guys, Just had a set of these off ebay with the built in resistor but they will not power up and the standard bulbs work fine? Have run power to them and they work, any ideas what could be up and have these type of bulbs been a problem in e46s before. Thanks Quote Link to comment Share on other sites More sharing options...

Welsh 320d Posted January 4, 2018 Author Report Share Posted January 4, 2018 Would the standard bulbs not work then if contacts were corroded? Quote Link to comment Share on other sites More sharing options...
2clubsp Posted January 4, 2018 Report Share Posted January 4, 2018 Yes, normally, but with much less current flowing it can make a difference. Quote Link to comment Share on other sites More sharing options...
RIZ Posted January 4, 2018 Report Share Posted January 4, 2018 As above flip them around, led bulbs are polarity sensitive they only work one way unlike standard bulbs. Daz 330 Cs 1 Quote Link to comment Share on other sites More sharing options...
Benji83 Posted January 5, 2018 Report Share Posted January 5, 2018 (edited) I don't know if this helps you but I bought some LED number plate bulbs and they came in a pack of 10. I obviously only need the two I've got in and a spare set, so I can post you a pair if you want? They're bright and have lasted me months without issues.
