I need headlights, and have always thought that the lighting for the Vanagons was sorely lacking.  So, I am considering Xenon lights.  Are there any drawbacks to using these as opposed to stock lights?  Specifically, I am looking at an auction on Ebay right now...

If they really don't use more draw, are brighter and fit into the existing spots with no modifications I don't see much of a negative...

Thanks..
