These fit just fine in my 2014 Sienna. These are much quieter than the previous generation. I had my doubts but the loud whirring sound present with the old version is not present with these.
I don't know if I see a 900% increase in brightness. I feel like that would be a pretty obvious different. The silver lining here is that I don't think I want a giant increase in light. Both the older version and this current version have plenty of light as far as I'm concerned.
Hopefully the lifespan is a 900% increase over the last version which only lasted about 10 months. Ok, I'd settle for a 50% increase.
