Halogen is still the simplest upgrade path for many vehicles
A better halogen bulb keeps the original bulb type, connector, heat profile, and beam control. The tradeoff is that performance halogens usually gain output by giving up some lifespan, while white-look halogens often give up output for color.

How to use the halogen data
Brightness, lifespan, and color are tradeoffs
Halogen bulbs are still easy to install, but package claims can be misleading. A brighter bulb may have a shorter lifespan, a whiter bulb may be dimmer, and high-wattage bulbs can add heat and wiring stress. The chart separates measured output from marketing language.
Match the housingReflector and projector headlights can rank the same bulb differently.
Watch wattageAnything above standard wattage needs more caution for wiring, heat, and road use.
Do not chase blueVery white or blue-look halogens usually trade away useful road light.
