The light it omit has a bluish tint FYI They look fine for a few minutes after turning them on, but then they turn a very undesirable shade of purple-ish blue
Sure enough, they're pretty blue
The middle of the bulb got hot,black, and started smoking
Not all are the same shade either
After being on for awhile the bulbs overheated just a 1/2 hour to an hour
The difference in the lighting inside my cab now is like night and day compared to the OEM HT 908 bulbs
