Sylvania 1157A.TP Basic Miniature Bulb - 10 Pack

The Sylvania 1157A is a dual-filament miniature bulb purpose-built to replace factory tail light, brake light, turn signal, and parking light bulbs on a broad range of vehicles. It fills a critical safety role — these are the lights other drivers depend on — so fitment accuracy and consistent output matter. As a direct OEM replacement, the 1157A slots into factory sockets without modification and meets industry performance standards right out of the box.

Sylvania manufactures these as an OEM-tier light source supplier, which means the materials and construction match what came in your vehicle from the factory — not a budget knockoff. The 10-pack format is practical for shops, fleet owners, or anyone running older vehicles that cycle through bulbs more frequently. Keep in mind that incandescent dual-filament bulbs dim gradually before they fail outright, so Sylvania recommends replacing them in pairs when one burns out to maintain even light output across both sides.
