I used Sylvania Silver Star halogen bulbs for ages, back when there wasn't much to choose from besides HID or crap halogen.
During the last 10 or 12 years of use, they consistently survived about 14 months, or 2 months beyond warranty coverage.
Just like clockwork, or was it? I will never give Sylvania a penny of my money again.
This use was in my former '07 Tundra, which had horrible lighting, only used on weekends, but always with all lights on.
The Tundra double cab was larger than my Warlock, but apparently a shade of grey that was near invisible to other drivers.
In my Warlock, I've used inexpensive Fahren and Auxito low-profile LED bulbs from Amazon, in factory projector housings.
The Fahrens in the low beams are about 2 years old, and Auxito in the high beams are a bit less.
They are fantastic! I rarely get flashed, and I can drive on rural highways at 50 mph with only the low beams on.
The Fahrens have a 3-year replacement warranty, and the company have been phenomenal to work with.
I don't recall the warranty on the Auxito, but it is at least 2 years. I will update when I find it.
If I were starting again, I would find used factory projector housings and Fahren LED bulbs, all the way.
One caveat: most LED bulbs sold during the past 2 years have become brighter every few months.
I have some concerns that they may all have become too bright and cause issues with oncoming traffic unless they are correctly aligned.
I would still choose Fahren LED, but might choose to direct them a bit lower than the standard positions.
This video refers to LED, but I'm convinced that it should apply to all headlights.
