It works just fine. Just remember a few points.
Dash needles are orange. This needs to be changed. I just scraped the orange off mine and painted them white.
LEDs are directional, bulbs are not. Therefore you need to mount them further back to get the same effect. This will involve some surgery on the bulb holders.
Check you have the correct polarity BEFORE you reassemble the whole dash. Trust me on that one.....
As for 5300mcd, they're fine. A little dim in the day, perhaps.
