I don't completely understand your question. The 6014 is the generic high/low round lamp made by all of the major lighting companies. what are you thinking of changing to? You could step up to halogens... heres a quote i found on the 6014's SEEING THE LIGHT Years ago, all headlamps were sealed beams. So if a vehicle needed a replacement headlamp for a 1980s vintage or older vehicle, there were only a few basic sizes of round and rectangular beams: those for two headlight applications (6014 round hi/low sealed beam and 6052 rectangular hi/low beam) and those for four headlight systems (4000 round low beam, 4001 round hi beam, 4652 rectangular low beam and 4651 rectangular high beam). Most of those older-style sealed beams were originally standard incandescent lamps. In 1978, the federal government revised its headlamp regulations to allow the use of "halogen" sealed beams. Halogen lamps are brighter and last longer than regular lamps because the bulbs contain a small amount of bromine gas (one of five elements in the halogen chemical family). The bromine gas allows the use of a smaller, hotter tungsten filament because bromine redeposits the microscopic particles of tungsten that boil off the filament back onto the wire. This extends the life of the bulb and prevents the glass from darkening as the bulb ages. Halogen lamps are a good upgrade for these older sealed beam applications because halogen lamps produce more light with the same or less current. Halogen sealed beams have an "H" prefix on their part number and are available in various sizes for round, rectangular and low-profile rectangular headlamps. How much brighter are they? A conventional incandescent bulb generates 16 to 18 lumens of light per watt compared to 20 to 22 or more lumens per watt for a standard halogen bulb (some high output halogen bulbs produce as much as 28 to 33 lumens per watt). The higher output of a halogen headlamp throws more light on the road to improve nighttime visibility and extend the driver's visual range. The light is also whiter than a regular incandescent bulb, which improves visibility too.
