W110, W113, W114, W115, W123 Performance H4 Headlight Upgrade
7 inch diameter pair of headlights with replaceable H4 bulbs that will really light up the countryside but won't blind oncoming drivers.
For the past 20+ years, we have promoted H4 headlight upgrades for these old Mercedes. The original sealed beam headlight bulbs lacked light output, and we found them sometimes downright "sketchy" on dark roads, especially when deer were known to be present.
