Rear Tail Light Socket Harness (81555-04150) – The Fix for Flickering Tail Lights on Your 2005-2015 Toyota Tacoma
Is your Tacoma's tail light flickering when you brake? Does it dim when you turn on your headlights? This isn't a bulb issue – it's a wiring failure. The OEM socket harness (part #81555-04150) corrodes over time, causing dangerous electrical faults. We've engineered a direct replacement that fixes it permanently.
Why This Harness Works When Others Fail
Toyota Tacomas (2005-2015) suffer from a known wiring flaw in the rear tail light assembly. The original socket harness corrodes where it meets the body, causing:
❌ Brake lights to flicker or fail
❌ Turn signals to dim
❌ Parking lights to stay on
❌ Grounding issues that drain your battery
Our 81555-04150 Rear Tail Light Socket Harness solves this with:
✅ Identical OEM Specs: Matches Toyota's exact wiring diagram, connector shape, and mounting points.
✅ Weatherproof Seals: Prevents moisture intrusion (a top cause of corrosion).
✅ Dual-Filament Socket: Works perfectly with 1157/2057 bulbs (no bulb compatibility issues).
✅ Double-Lock Connectors: Stops loose wires from causing intermittent faults.
Installation is Effortless (No Tools Needed)
Disconnect the old harness from the tail light assembly.
Plug in our pre-assembled harness – the connectors only fit one way.
Secure with the OEM mounting clip.
Done in 5 minutes. No wiring experience required.
