The Future of Halogen Bulbs
Today’s HIR (Halogen Infra-Red) incandescent light bulbs produce 75% of the light output of HID headlights at 25% of the cost. They are a single filament bulb with the same base and o-ring style as a 9005 or 9006 headlight bulb.
These bulbs attain light levels 75% to 110% brighter than stock as a result of an engineering process by GE that deposits multiple, yet almost invisible, layers of semi-reflective coating on the surface of a specially shaped quartz bulb. This coating reflects a portion of the infrared energy emitted by the filament back onto the filament, causing it to glow brighter and emit more light from the uncoated forward portion of the bulb. Although the filament gets hotter, the glass does not.
These bulbs generate NO MORE heat than a regular halogen bulb, and they draw the same electrical current as the stock bulbs that they replace. These are a great option if you wish to upgrade your stock 9006 or 9005 halogen bulbs because they will be a near direct plug-and-play upgrade. The cross-reference numbers are: 9005 bulb = 9011 HIR bulb; 9006 bulb = 9012
If you have access to a high-quality HID system, that is still a better option, but if you want to upgrade on a budget, consider Halogen Infra-Red light bulbs.
