Mini-bump, I just bought some of the highest powered version 168 bulbs off Ebay (these except without the projector lens
https://www.superbrightleds.com/more...wer/1701/4011/) to use as parking lights. They claim 350 lumens and 3W, which I can believe based on the size of the metal housing and the claimed current levels (lower current LEDs are more efficient). If that's correct, I'll get a whopping 1/3 of a standard HB2 low beam's brightness from the parking lights alone! Combined with DRLs (the main headlights at lower voltage) I might have as much light as a full standard HB2 halogen!
I also have my finger on the trigger for one of the LED kits with a nice fat heatsink for the headlights when they go out, which may not be anytime soon. Someone on Spyderchat posted a picture of the 50W/bulb versions and it is staggeringly bright compared to a Sylvania Silverstar, so I think a 30W will do nicely. Beam cutoff is messy compared to stock but when taller tires go on the rear, my car will be raked forward by more than 1 degree from stock.
