*Compared Only to SYLVANIA BASIC
Replacing only one old, dim headlight bulb with a new, brighter bulb creates uneven light, impacting your downroad visibility.
2. SMART MAINTENANCE
Headlight bulbs are on at the same time, so when one burns out the other is not far behind. Save time and replace together.
3. MATCHING PAIR
When upgrading to better headlight bulbs, replace in pairs to ensure equal brightness and color so you can see better at night.
