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
