mallard Report post Posted December 3, 2016 After my failed one year experiment with XenonDepot LED bulbs in my 2013 halogen projectors I decided to look around to see if there were any better halogen bulbs out there. I found this discussion on candlepowerforums: http://www.candlepowerforums.com/vb/showthread.php?390701-2014-Sierra-Projector-Headlamps-best-upgrade I took a chance on the Vosla +30 HIR2 bulbs and I have to say they're a noticeable improvement over the stock halogen bulbs (lets not even talk about how much better they are than the LEDs). Beam reach is significantly better, they really throw the light down the road. I think the color is whiter as well but note that the bulb lifespan is also shorter than the long life bulbs. You can get them on Amazon or GM Parts Direct. Price is very competitive with current HIR2 offerings. Share this post Link to post Share on other sites
