# Diode Dynamics EP29 LED Turn Signal Flasher Features Compatible with LED bulbs. Prevents hyperflash errors. Simple swap for original module. Direct fitment and proper sizing. Flasher Hyperblink Fix. Why do you need this module? When your factory turn signal bulbs go out, your vehicle's flasher senses that less power is being used, and it will blink the turn signals quickly to alert you. Since LED bulbs use less power, you get the same fast blinking, known as "hyperblinking," even though the LEDs are functioning just fine. Basically, your car thinks the bulbs went out! To slow down the blinking to regular speed, you can add resistors to increase the circuit's power consumption again. However, whenever possible, replacing the flasher with a module like this is the easiest option. Simply unplug your original flasher from under the dash, and swap it with this one to prevent hyperblinking. Quality. The flashers distributed by Diode Dynamics are produced by industry leaders such as Novita. Watch out for generic cheap flashers, as many are slightly too large and may not fit properly in the socket. - Direct replacement for your vehicle's flasher relay - Direct fitment and proper sizing - Simple swap for original module - Prevents hyperflash errors - Compatible with LED bulbs This Part Fits: Year Make Model Submodel 2002 Cadillac Escalade Base 1999-2002 Chevrolet Silverado 1500 Base 1999-2002 Chevrolet Silverado 1500 LS 1999-2002 Chevrolet Silverado 1500 LT 2002 Chevrolet Silverado 1500 WT 2001-2002 Chevrolet Silverado 1500 HD LS 2001-2002 Chevrolet Silverado 1500 HD LT 1999-2002 Chevrolet Silverado 2500 Base 1999-2002 Chevrolet Silverado 2500 LS 1999-2002 Chevrolet Silverado 2500 LT 2001-2002 Chevrolet Silverado 2500 HD Base 2001-2002 Chevrolet Silverado 2500 HD LS 2001-2002 Chevrolet Silverado 2500 HD LT 2001-2002 Chevrolet Silverado 3500 Base 2001-2002 Chevrolet Silverado 3500 LS 2001-2002 Chevrolet Silverado 3500 LT 2000-2001 GMC Jimmy Diamond Edition 1998-2000 GMC Jimmy Envoy 1998-1999,2001 GMC Jimmy SL 1998-2001 GMC Jimmy SLE 1998-2001 GMC Jimmy SLS 1998-2001 GMC Jimmy SLT 2002 GMC Sierra 1500 Base 2001 GMC Sierra 1500 C3 2002 GMC Sierra 1500 Denali 2002 GMC Sierra 1500 HT 1999-2002 GMC Sierra 1500 SL 1999-2002 GMC Sierra 1500 SLE 1999-2002 GMC Sierra 1500 SLT 2002 GMC Sierra 1500 WT 2002 GMC Sierra 2500 Base 1999-2002 GMC Sierra 2500 SL 1999-2002 GMC Sierra 2500 SLE 1999-2002 GMC Sierra 2500 SLT 2002 GMC Sierra 3500 Base 2001-2002 GMC Sierra 3500 SL 2001-2002 GMC Sierra 3500 SLE 2001-2002 GMC Sierra 3500 SLT 1993-1995 GMC Yukon Base 1999 GMC Yukon Denali 1993 GMC Yukon GT 1996-1997 GMC Yukon SL 1993-1999 GMC Yukon SLE 1995-1999 GMC Yukon SLT 1994 GMC Yukon Sport ## Details - **Price:** 50.96 CAD - **Vendor:** Diode Dynamics - **Type:** Light Accessories and Wiring ## Variants | Variant | Price | Available | |---------|-------|-----------| | Default Title | 50.96 CAD | In stock | ## Images - Photo - Primary - User 2 - User 1 - Logo Image - Logo Image --- > Source: [Standard Auto Part](https://www.standardautopart.com/products/diode-dynamics-ep29-led-turn-signal-flasher) > Updated: 2026-07-05
