I did also replace this blub a while ago.

Does anybody of you have a bluish rubber piece fitted on the blub? I had one and it will make the letter glow flourocent blue when fitted.

I am just curious to see if this is oem or not? Also same goes for vents knob in dash. Arrow will glow flourocent blue.
