1157 to 3157 Conversion Harness - Plug & Play Resistor Kit Prevents Hyperflash

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 1157 to 3157 harnesses with integrated resistors

LED Bulbs (OPTIONAL): 1 pair of 3157 bulbs in standard (Pro) or Signature Series (MAXX)

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.
