Question 1 : I noticed my xenon headlights are 2 different colors. Strange I didn't notice it earlier, must have 2 different bulbs in there . One is white and one is purplish. Any recommendations on brand and model xenon bulbs for an XK? (I like the more bluish tint on HIDs)
I don't want to spend top dollar, nor do I want junk.

Question 2 : What battery would people recommend for the XK. I heard lead acid is fine and it doesn't need AGM.
-Thanks

 

I believe the consensus here is go AGM. I have lead acid right now but will switch to AGM when this one is done. Do a forum search and you can see what others say.

No help on the bulbs as I've never looked into it.
