Well, turned out to be another plug'n'pray-installation.
My H1-bulb (in my EUDM Accord, not the NSX) is placed in an adapter. The spring securing the bulb, is locked over the wings of the adapter, and not the bulb itself. Se pics.
Any good suggestions for solving this problem easily? I could dremel a similar adapter to fit (as I do not want to destroy the OEM one) but cannot find anything like it on the net.
these?
