My lamps haven't given up the ghost but they do seem to be growing more dim. The lamps still look new so it doesn't have to do with the lamp itself. I purchase a pair of D1's with the ignitor. The Auto leveling system incorporates a retainer. ( Left) They don't use the common spring clip. Is there a "safe way" to separate the bulb from the ignitor to put the retainer on the new bulbs? I appreciate the pointers on this one.
