Fitment Notes

  • Compatible with any vehicle using a standard CF18 (LM449) turn signal flasher relay - plug-and-play direct replacement for the factory CF18 module.
  • For Toyota trucks and SUVs (including Tacoma, 4Runner, Tundra, Sequoia, and Highlander): compatible only with trim levels that do NOT feature factory Daytime Running Lights (DTRL). Not compatible with DTRL-equipped Toyota trucks.
  • Not compatible with most newer vehicles that do not use a CF18-style flasher. Contact Diode Dynamics to confirm compatibility if unsure.
  • Compatible with both LED and standard incandescent turn signal bulbs - eliminates hyperblinking caused by LED bulb installation with no additional resistors or wiring required.
  • Maximum load rating: 150W continuous (approximately equivalent to six total incandescent turn signal bulbs - three per side).
  • Fully functional on Subaru OneTouch-equipped vehicles - overrides the factory fixed 3-blink with the user-programmable blink count.

Features

  • Eliminates LED hyperblinking: replaces the factory CF18 flasher with an intelligent module that maintains correct blink rate regardless of bulb power draw - no resistors, no load equalizers, no additional wiring needed.
  • Tap-to-Signal: a single tap of the turn signal lever triggers a programmable series of automatic blinks - ideal for lane change signaling without holding the stalk. Number of blinks is user-programmable via the included guide.
  • Eight unique hazard functions: built-in strobe, slo-mo, and wig-wag hazard modes can be applied individually, in combination, or layered with strobe for eight total distinct hazard patterns - all programmable.
  • Arrival and Departure Modes: pressing the lock or unlock button activates the turn signals in a steady glow for 10-90 seconds (adjustable) to illuminate the surrounding area when approaching or leaving the vehicle at night. Can be disabled.
  • Embedded microcontroller with proprietary Diode Dynamics software - provides all programmable functions without any external controllers, apps, or additional hardware.
  • 8-terminal relay construction with the same physical footprint as the factory CF18 (LM449) flasher - direct plug-and-play swap with no wiring modification.
  • Tested and rated for a continuous maximum load of 150W - supports up to six total incandescent-equivalent turn signal bulbs without overloading.
  • Compatible with Subaru's OneTouch lane-change signaling system - programmable blink count fully overrides the factory fixed 3-blink sequence.
  • Designed, programmed, and assembled in the USA by Diode Dynamics in St. Louis, Missouri; backed by a 3-year replacement warranty.

Product Description

The Diode Dynamics DD4015 SmartTap CF18 LED Flasher Module is a direct plug-and-play replacement for the factory CF18 (LM449) turn signal flasher relay used across a wide range of Lexus, Scion, Subaru, Toyota, and Pontiac vehicles. At its most basic level, the SmartTap solves the hyperblinking problem that occurs whenever LED turn signal bulbs are installed: because LEDs draw less power than incandescent bulbs, the factory flasher interprets the lower load as a burned-out bulb and rapidly increases the blink rate. The SmartTap eliminates this behavior entirely, maintaining the correct standard blink rate with any LED or incandescent bulb - no inline resistors, no load equalizers, and no wiring modifications required.

Beyond hyperflash prevention, the SmartTap adds a full suite of programmable intelligent signaling functions through an embedded microcontroller running proprietary Diode Dynamics software. The Tap-to-Signal function enables single-tap lane change signaling - one touch of the stalk triggers a user-defined number of automatic blinks, keeping the driver's hands free. The built-in hazard system includes strobe, slo-mo, and wig-wag patterns that can be applied individually or combined for up to eight unique hazard configurations. The Arrival and Departure mode activates a steady-glow turn signal when the lock or unlock button is pressed, providing up to 90 seconds of illumination around the vehicle - adjustable in duration or fully disableable. On Subaru vehicles equipped with OneTouch lane signaling, the SmartTap fully overrides the factory fixed 3-blink sequence with the programmable blink count, with no modification or workaround required.

The SmartTap is rated for a maximum continuous load of 150W - equivalent to approximately six full-power incandescent turn signal bulbs - making it compatible with mixed LED and incandescent setups without any risk of overloading the module. Installation is a direct swap: unplug the factory CF18 flasher and plug in the SmartTap in its place. All programming is done using the included guide and the vehicle's existing controls - no app, no Bluetooth, and no additional hardware needed. Designed, programmed, and assembled in the USA by Diode Dynamics in St. Louis, Missouri, the DD4015 is backed by a 3-year replacement warranty.
