The purpose of this thread was to compile info so it can be easily shared with others. I'm sure a portion of people already know about this.
Want a headlight upgrade that's not HID or LED? The answer is HIR! With some slight modifications to the bulb bases you can replace your 9006/9005 stock bulbs with 9012/9011 bulbs not only are these brighter than stock but they have nowhere near the added glare of HID or LED. Here is some info (from the link). I highly reccomend that you make sure your headlight lenses are crystal clear. If not attempt to properly restore them don't use that BS bug spray, toothpaste whatever. Last resort should be new assembly's as they aren't as good as OEM.
High Beam
9005: 1,860lm +/- 12%
9011: 2,500lm +/- 15%
Potential max increase of 75.6% more lumens
Low Beam
9006: 1,095lm +/- 15%
9012: 1,875lm +/- 15%
Potential max increase of 131.7% more lumens
