Its not really to make the housing work better, its to make them look better. Thats why you want to do this right?
Get new bulbs. Halogen wear and get dimmer over time. There are some phillips bulbs I used in my jetta that were the brightest available. I’ll see if I can figure out which ones and edit.
This is a tech forum man, you’d be better off checking with a specific forum about your car. I can only give you anecdotal information about my cars that may or may not translate, but let me say this.
You have a car thats from 2006, its 12 years old now. Why do you want to spend $300 on housings plus another $100 for a decent set of LEDs just to put out the same amount of light a good halogen would?
Save your money. Its not going to improve anything more than a resurface and a good halogen would.
As far as LEDs go, I typically stick with genuine CREE stuff since its cheap as hell and works ok.
I cant give you any info about the DNA brand but google and youtube can answer most of the questions you have about LEDs and Housings.
EDIT: I believe these were what I used on my jetta. Big difference overall. When I got the car used the lights were lethargic at best and forced me to use high beams. The housings were also weathered and dull. After resurfacing and replacing the bulbs they work as expected.
Note: these might not be the correct fit, youll have to look up what you need but odds are they make it in your size.
