1999-2007 Silverado/Sierra DoubleUp Tail Light Mod

Simple plug and play harness that combines your reverse light and turn signal into one of our Signature Series Switchback bulbs.  WHY?  Well, because we can and it's cool. When have you ever seen an amber turn signal on a Cat Eye Chevy? I mean, come on. What's not to love.  Oh, also SAFETY. This kit also doubles up (see what I did there) the park/brake signal so those two functions now use BOTH of the red portions of your tail light. BEST OF ALL this mod will work with literally ANY tail light, be it stock or aftermarket, no matter the style. This setup will work with whatever you're running already.  Looking for a new set? We have plenty of styles available. Peep the related products in this listing for more info.  OBNOXIOUSLY BRIGHT is the best way to describe the MAXX option. Trust me, you WILL be seen with this option installed.    WHAT'S INCLUDED? WIRING: 4x Sparksmith Exclusive DoubleUp harnesses. Two with integrated resistors for the Reverse/Turn Switchback bulbs, two for doubling up your Park/Brake setup. LED BULBS: 2 pairs of 3157 Switchback bulbs in standard (Pro) or Signature Series (MAXX) LED BULBS (OPTIONAL): 2 pairs of 3157 Red bulbs in standard (Pro) or Signature Series (MAXX) DON'T FORGET: The pictures/videos in this listing show the MAXX bulb setup. You can keep using your existing bulbs if you want.
