Default 2010 RX350 HID Replacement

I realize some of these threads are old. But I just replaced my HID bulb and posting to multiple places so the next person can more quickly find info.

My passenger-side HID went out on my 2010 RX350 recently. I decided to replace the bulb myself to rule out the ballast and save money.

I wanted the same color so I purchased the Phillips 4300K D4S bulb from Amazon ($41, love Prime) instead of local Napa ($101) or dealer ($175). I also picked up 10-pack cover clips ($8) since old ones wouldn't hold very well.

I removed the clips/cover per the manual, disconnected the battery +cable, and followed these 9 steps:

After reassembling everything, the headlight fired up but I lost usual seat/radio presets due to power disconnection. The unlabelled bulb was obviously fried.

Hope that helps someone.

Default HID xenon headlamp for 08 RX 400h

Hi all,
i need to know if the inside part of an HID headlamp, the part that holds the xenon bulb, can be changed, is that what the dealership would do if the bulb socket was damaged (melted) ? Or would I need to replace the whole headlamp assembly ?
