This item was not in the shipping box. When I called to see what happened,l was told that they would look in to the missing part. I received the items just this week along with a invoice a bill. I was billed the first time I ordered the items. I didn’t receive the items in the first shipment and should not be changed again.

These were an excellent LED replacement for our stock instrument panel bulbs, and they are dimmable. Work and look great.
The comment about the plastic rim is a fair point. Other than that, these bulbs are great. No electrical noise from them in my audio system (sometimes LED drop in replacements apparently cause that). The bulb material itself is rugged and grips better than glass, in case you have to be creative with your fingertips and/or needlenose pliers for bulbs that go in awkward, hard to reach places. Or so Ive heard...
These are great replacement bulbs for the incandescent bulbs. I gave it a 2 star because of the 9 bulbs I purchased, only three fit my military press-to-test indicators. The remaining 6 had to be turned down on a lathe to fit the holder. Cause: There is a white ring between the metal base and the plastic dome. This ring is too large a diameter to fit the holder. After reducing the diameter to that of the dome itself, all the bulbs fit and functioned fine.

Very, very dim.... pretty much useless
Very Dim, I thought by using an LED light in the cabin it would be brighter. The original regular bulb is 5 times brighter!
Very dim. About 1/4 the light output compared to the incandescent. Not useable as instrument lights.
