X3 ^ ddm kits. . They been in a few rides I've owned and current ones except cts wich is oem
I had some eBay ones they lasted fairly long il give them that but color output and the jittery and fluttering light . Was about all I could take . Fluttered a flickered so bad I coulda acted like a cop car.

 

Next time ill deff order a better kit. And I understand the argument about which color bulb is best. But in my eyes I'm comparing the 10k to the crappy sealed beams. Which is a vast improvement. And the really white color doesn't seem to absorb on the wet Washington roads as badly.
