Perfect replacement
Fitted perfectly...make sure you look at your faulty one before purchasing...the updated version on may sites will NOT fit...but this matched my original older one. Not as bright as I would like, more "warm" than "Arctic white" ..but that actually may be a good thing for the eyes!

Get the right bulb
This is the right bulb, it has the 4 pin connection, be careful to avoid the 2 pin ones. The after market (ie. Not Osram) 4 pin ones tend to be LED and tend to not fit and not work 50% of the time.

Disappointed
Just opened this light and it’s not working. I bought it as a backup incase . And now my light is out opened this and I’m disappointed really. I have never had a problem before . Have bought another one hopefully it works because they are not cheap.
