    Product Information

    Description, Q&A, Specs & Installation

    Description

    Simple plug and play harness that prevents hyperflash when installing LED bulbs in your factory turn signals.  The optional bulb types available on the listing allow for a choice of White, Amber, Red, or Switchback (most popular) function.

    Wire Harness: 2x Sparksmith Exclusive 3157 harnesses with integrated resistors

     

    CK vs Non-CK: Okay, this one can get a bit confusing. But compare your sockets with the images below and choose wisely. Not sure what you have, read our blog for more info. Still not sure, contact us and we'll help you get the right parts!

    The Good Stuff: These aren't your cheap $15 Amazon adapters with those failure prone gold anodized resistors. No sir. This is a high quality setup that is hand made right here in the good ol' USA. Better still, we'll throw in some stainless screws to mount the resistors and dielectric grease so you can be sure your factory sockets will be in top shape for years to come.

    Harness: 2x 3157 Jumpers w/ integrated slim line resistors
    Hardware: 4x #6x1/2" stainless steel, self drilling screws
    Protection: 5 gram tube of dielectric grease
