Generic 1157 3-Wire Tail/Brake/Turn Socket — 2-Pack Direct Replacement for Classic GM (1969–1991)

These two 3-wire 1157-style sockets provide a direct-replacement connection for tail light, brake light and turn signal bulbs on many classic GM vehicles.

Designed as a straightforward electrical socket replacement, this 2-piece set fits a long list of Buick, Cadillac and Chevrolet models from the late 1960s through the early 1990s. Each socket accepts a standard 1157 dual-filament bulb and handles park (tail), stop (brake) and turn functions through three separate wires. The parts are delivered fully assembled and inspected, so they’re ready to swap into the existing harness without splicing or modification on compatible vehicles.

Which vehicles and years will these 3-wire sockets fit?

This socket set is compatible with many GM applications spanning Buick, Cadillac and Chevrolet model lines. Fitment covers numerous model years across Centurion, Century, Electra, LeSabre, Riviera, Regal, Skylark, Wildcat, DeVille, Eldorado, Fleetwood and multiple Chevrolet pickup, Suburban, Blazer, Camaro, Impala and truck series.

• Accepts 1157 dual-filament bulbs used for tail/stop/turn circuits.
• Compatible with vehicles listed in product details (1969–1991 model years).
• Works with straight 3-wire socket versions and many factory harnesses.
• Ideal for GM cars, trucks and wagons where original sockets failed.

How easy is installation for a DIY restorer or mechanic?

Installation is typically quick and straightforward: unplug the old socket, remove it from the housing, and plug the new assembly into the existing bulb and harness. Because the sockets come assembled and inspected, you’ll avoid trimming or soldering in most standard swaps. For vehicles with corroded pigtails, minor harness cleaning or replacement of the lead wires may be required.

• Pre-assembled—no on-site assembly required.
• Direct plug-in replacement for standard 1157 bulb holders.
• May require basic trim or harness cleaning on corroded connectors.
• Recommended tools: screwdriver, dielectric grease, basic hand tools.

What are the construction and quality details?

These sockets are manufactured to ISO9001 standards and undergo 100% inspection before shipment to ensure consistent electrical contact and mechanical fit. The materials resist heat from incandescent bulbs and provide reliable contact points for the dual-filament design. They are intended as durable replacement parts suitable for restoration or maintenance use.

• Made in Taiwan to ISO9001 quality standards.
• 100% inspected prior to shipping for electrical reliability.
• Complete assembly—ready to install into original housings.
• Designed for outer stop & turn plus parking light function.

Will these sockets work with LED bulbs or modern upgrades?

The sockets accept standard 1157-form bulbs whether incandescent or LED retrofit equivalents with the same base. When using LED replacements, verify polarity and load-resistance because some LED bulbs require load resistors or electronic flasher units to operate correctly in original GM circuits. Always test lights after installation to confirm turn, brake and tail functions.

• Accepts 1157-style LED and incandescent bulbs with matching base.
• LED conversions may need resistors or flasher updates for proper flash rate.
• Test all circuits after installation for correct function and polarity.
• Use dielectric grease to protect contacts from corrosion when possible.

Who this is for: This 2-piece 3-wire socket set is aimed at classic GM owners, hobbyist restorers, and mechanics who need a dependable, plug-and-play replacement for failed tail/brake/turn lamp holders. If you’re repairing a Buick, Cadillac or Chevrolet model from the late 1960s through early 1990s listed in the fitment, and you want a ready-to-install, quality-inspected socket for 1157 bulbs, this kit provides a practical and cost-effective solution.
