GROBARPART 3156 Daytime Running Light Socket Harness — 2-Wire Pigtail for Chevy/GMC 2000–2007, Plug-and-Play

The GROBARPART 2-wire 3156 daytime running light socket harness is a direct-fit replacement pigtail for specific Chevy and GMC models, restoring secure bulb connection for DRL, turn signal, brake and tail lamp sockets.

If a burned connector, corroded socket, or a brittle wiring pigtail left your daytime running lights or turn signals unreliable, this GROBARPART harness offers an OEM-style replacement. It accepts a broad range of wedge-base bulbs (3156/3056/3456/4156 and related types), matches common OE part numbers, and is designed for plug-and-play installation on many Chevrolet Avalanche, Silverado and GMC Sierra and Yukon trucks and SUVs.

Which vehicles and OE part numbers does this socket harness fit?

This harness targets older GM full-size trucks and SUVs where the factory sockets wear out. It lists compatibility with model years and variants across Chevrolet and GMC lines and replaces several manufacturer part numbers used on lighting sockets.

• Chevrolet: Avalanche (2000–2007 variants), Silverado 1500/2500/3500 (2000–2007 configurations including HD and Classic)
• GMC: Sierra 1500/2500/3500 and Yukon/Yukon XL (2000–2007 model ranges noted)
• OEM cross-reference: replaces part numbers like 19258649, 15306157, 15306358 and similar socket references

How do I know this harness will work with my bulb type?

The GROBARPART pigtail is built to accept multiple wedge-style bulbs commonly used for daytime running lights, turn signals, tail and brake lights. Confirm the bulb base type in your vehicle's manual and compare to the listed compatible bulbs before ordering.

• Compatible bulb types: 3156, 3056, 3456, 4156 plus related 3057/3155/3357/3457/3757/4057/4114/4157
• Designed for standard wedge-base bulbs rather than bayonet or twist-lock styles
• Check your vehicle lamp assembly for the same socket shape or cross-reference your original part number

What are the installation and durability features of this replacement socket?

The harness arrives as a ready-made 2-wire pigtail so you can swap it in without cutting or splicing when the factory connector has failed. Molded plastics and reinforced wiring aim to resist vibration and typical under-hood exposure; still, proper routing and securing during installation improve longevity.

• Comes as a pre-wired 2-wire pigtail with molded connector housing for a snug fit
• Plug-and-play swap for sockets that match the listed OE cross-references
• Quality control tested before shipping and backed by a one-year limited warranty

Will this repair require special tools or electrical work?

Most installations are straightforward and use basic hand tools. If your original harness was clipped or soldered into a larger loom, you may need a few extra steps; otherwise the replacement is intended for direct connection into the lamp housing.

• Typical tools: screwdriver, trim tool or pliers for removing retainer clips
• No specialized crimpers or soldering required for clean plug-in installations
• If the existing wiring is damaged beyond the connector, minor splicing or professional assistance may be necessary

Who this is for: This GROBARPART 2-wire 3156 daytime running light socket harness is aimed at owners of Chevy Avalanche, Silverado and GMC Sierra/Yukon vehicles from the listed years who need a reliable, cost-effective connector replacement. It suits DIY mechanics who want a plug-and-play fix for flickering or nonfunctional DRLs, turn signals, tail or brake light sockets, fleet maintenance teams replacing worn sockets, and restorers updating aged wiring harnesses. Before purchase, verify your vehicle year, lamp assembly style and bulb base to ensure a match with the compatible bulb types and OE cross-reference numbers provided.
