2006 DTS Performance Lux III
The HID bulb doesn't get brighter when the high beam is on. There is a shudder in the assembly that opens and closes allowing more light through the projector lens. I haven't heard of anyone changing the hids to led. But it's doable. Stay away from the cheap junk on ebay and amazon. You want a quality led that will last.
