Minor update, adding mostly for posterity.
I've got 121k on the truck now. My HIDs used to occasionally flicker, but it wasn't bad or very regular. Recently I noticed the driver's side was flickering all the time, even when I was just sitting a stop light, so I figured it was time for new bulbs.
I tried the $30 DMEX HIDs from
Amazon. They're decent and if you're strapped for cash they'll work, though I'd recommend getting the 4500-5000K color. Up close they seem bright. Cut-off was fine. They didn't seem as bright as the OEM bulbs at a distance (shining down my alley), but I think that might be due to the fact that they are 6k bulbs so the blue-ish light doesn't seem as bright at a distance.
Because I wanted *better* than OEM, I ended up ordering a set of Philips Xtreme Vision. Cost shipped from Germany was $156 for the pair off
ebay. You can also order from lichtex.de directly. I was a bit concerned about fakes but Lichtex seems highly reviewed. the QR codes scanned fine, and the bulbs show up by Philips as being genuine. I think they claim 5000K color but are definitely slightly yellow-ish and I would've pegged them at ~4500K. They definitely are brighter than OEM and shine well down my alley. I don't know that they're 150% of OEM brightness but I'd definitely guess it achieves the same brightness for 10-20% more distance.
Pro tips for headlight replacement:
- Start with the passenger's side as it's easier to see WTF you're doing
- Use latex gloves when swapping the bulb. You shouldn't need to touch the bulb, but just in case...
- For the driver's side you can leave the battery in place but pop out the clip and remove the washer fluid fill tube
- I'd definitely recommend new gaskets to protect the bulbs from moisture, given how tight new gaskets make the ballast fit vs how easy it is to reinstall the old ones.
