LM487 đ ⥠LED Blinker Flasher Relief
Honestly, nothing is more distracting than a turn signal that wonât behaveâespecially after swapping in LED bulbs.
This LM487 LED flasher turn signal relay module is designed for the kind of over-flashing / warning-light weirdness people run into when the flasher logic doesnât match the new LEDs.
What this is (and why it exists)
This is a 10-pin flasher relay module intended for specific GM GMT800 vehicles (2003â2007 range, depending on configuration).
The biggest appeal is that itâs meant to help address over-flashing and related turn-signal behavior when LEDs are involved, so your indicators act more like youâd expect.
Quick heads-up: the listing notes itâs only for GMT800 and not for GMT900 or other basic modulesâso checking what you already have matters.
Key Features
Replaces LM487 flasher relay and is listed as compatible with multiple GM part numbers (including 10383321, 15764135, 10383320, 15231201, and EFL-27).
Intended for GMT800 vehicles with a 10-pin flasher module / hazard warning flasher relay configuration.
Designed to help solve over-flashing and turn-signal issues that can happen when LEDs donât light up as expected.
Uses a PP plastic housing, intended for long-term use in harsher environments.
Best Fit For
This relay is best viewed as a replacement flasher module for the right GM setupâespecially if youâve got a 10-pin flasher module and youâre dealing with LED-related turn signal behavior.
- Drivers of compatible GM Chevrolet vehicles with GMT800 10-pin flasher modules
- People trying to fix over-flashing after replacing turn signal LEDs
- Anyone wanting the hazard/vehicle warning flasher behavior to match the new LED lighting setup
Why People Buy These
The âwhyâ is pretty simple: when LED bulbs replace older lighting, the vehicleâs flasher module may not respond how you expect.
This kind of relay is designed to help bring the flasher timing and warning-light behavior back into line for the intended vehicle configuration.
Final Verdict
If your GM has a 10-pin flasher module and youâre seeing over-flashing or odd turn-signal behavior after LED changes, this LM487 flasher relay is a practical option to consider.
Just make sure your current module matches the GMT800 / 10-pin description before you buyâbecause the listing explicitly cautions about GMT900 and other setups.
