I upgraded my headlights to Koito H4 and they rock!
This was based on recommendations from
Daniel Stern Lighting website. I was considering buying these from DSL, but at $179/pair my wallet said to look around a little...then I ran across a listing on CruiserTeq.com that had the
Koito H4 lights listed for $57.50, as Toyota Factory Upgrade parts for Landcruisers...and, since it's an upgrade, Toyota includes the Harness! Shipping was $21 but still ended up under $80 so I saved $100, and I got a free Toyota OEM harness with relays. I paid more than that just for the parts to build my own harness...That's how it goes some days.
So today I rolled into work at 6am (still plenty dark) and promptly installed and adjusted the lights...the Koitos are AMAZING! Super SMOOTH light pattern, they appear brighter overall than the Sylvania Silverstar H4 Sealed Beams that they replaced, and they look GOOD in the grill. VERY happy with this upgrade!
