2009 335, adaptive headlights, how to make them as bright as modern cars?

The headlights on my 09 LCI with adaptive function work, everything does what it should except throw decent light. My wifes base model mk6 jetta with halogens easily puts more light on the road. These things are dim to the point of being dangerous in the rain.

How can I perk them up? I'm halfway sure its just the age of the original bulbs, as I know HID bulbs wear out over time.

I'm tempted to put another stock set in, but dont want to fork out the cash and be disappointed with output still.

Anyone throw me some ideas on how to make these things perform even close to what modern cars can do? Had a mazda6 rental with HIDs that put these to absolute shame. Was next to a tesla this morning and then a new fusion right in front of him, didn't even look like my headlights were on compared to theirs.
