I've got a 2007 E-350 and would like to upgrade the single zenon headlights with a brighter bulb like the new Silverstar. Is it possible to replace these zenons with something better, brighter?

Thanks

 

I am not sure what is in there now. I'll need to pull one to see. I would prefer a more white/bluish light that provides more "down-road" illumination. I drive in some rural areas at night and the single zenon is horrible.

If anyone has already upgraded from the single zenon, please let me know what make and part you recommend.

Thanks!
