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.
