Upgrading to LED headlight bulbs can give you a whiter, brighter beam and a cleaner look, but fit and beam pattern matter far more than raw brightness numbers.
Not every LED bulb is street legal in every housing, and a poor pattern can blind other drivers. Check local rules and choose bulbs designed to mimic your original filament position.

How to choose
Find your bulb size
Check your manual or the old bulb base for the size, such as H11, 9005 or H7.
Check legality and housing
Bulbs meant for reflector or projector housings behave differently. Use bulbs rated for your type.
Aim after installing
Re-aim your headlights if the beam looks too high or scatters; glare is a safety issue.
