Thanks again for your insights and recommendations.
There is a thread around here titled something like "If you hate your yellow halogens..." with a lot of folks' experience. My take-away from that thread is that everybody makes a whiter/cooler color halogen than the OEM bulbs.
Anytime, hope it was helpful.
I understand that feeling about the OEM headlights, but it's pretty subjective. FCA doesn't make bulbs, I don't think the stockers are any worse than any other major brand halogens, it's just that all halogens grow dimmer and yellow with age, so anyone replacing old bulbs generally would see an improvement even if you put the exact same part number in. If you've ever replaced just one bulb out of a pair, you know what I mean.
FWIW, I rooted around in the barn just now for one of the OEM 9005 Sylvania high beams I pulled out of my '14 R/T Blacktop when I upgraded to 9011 HIR-1 bulbs. They were pretty yellow and dim, but if you look at the bulb, it's easy to see why.
There's some color variation in standard 4300k halogen bulbs, but nothing like the 5-6k you get from HIDs or LEDs. My 300C and my Charger each have three white "colors" now; roughly 5k from the HIDs, 4300 from the 9011 high beams, and 6k from the LEDs I put in the foglights to try to get as close as I could to the factory HIDs.
