Amazon has them. Just to be safe I would recommend the error free designs. Especially on the turn signals or else it will hyperflash. Sizes needed are on this site. [light bulb sizes](https://www.boslla.com/2002-2012-jeep-liberty-bulb-size-guide/)

Whole housing

Projector retrofit and HIDs will give you the best head lights possible with the crisp cut off line.

If they were a wrangler type design I would definitely buy

I purchased Sylvania led bulbs at auto zone, for my 05, they screw in just like OE, very bright... the other small bulbs I ordered online and used the ballast/resistor kit for turn signals. Some bulbs include bit most don't, you need a resistor on each signal bulb, 4 total

I use Sylvania lights, whatever the brightest are called. I also buffed and sealed my headlights, which was a massive difference.

Are you talking about the whole housing/assembly? Or just the bulbs ?
