I installed these and what a difference! The main reasons I chose these over the alternative(s):
1. Increased light output, with 70/65W (2000/1350 lumens, High-Output Xenon) vs the OEM 60/55W
2. Comparable lifespan to the stock OEM bulb sets
3. Didn't want the risk of a melted wiring harness with the "high power" bulbs
They show a measurable increase in usable light output and, as the power draw increase is negligble, you avoid the risk of overheating your stock wiring harness and/or connector assemblies. Plus, you don't get into that 6-9 month replacement cycle with those other "high power" or "ultra" type bulbs out there. They are on sale right now, 2 for $35. Here's the link: Osram's 70/65W Ultra High Efficiency +50 H4 bulb.
I also purchased upgraded Osram MiniXen® 2886X mini wedge (W2.1×9.5d) base bulb for my license plate markers. They are 85 lumens vs the stock 75 lumens. $4.62 ea. Shipping was $9.15. Total was $58.37.
