Frequently Asked Questions:

• How do the forward-facing lights work?

  Check out the dynamic pictures on the Product Details tab for an idea of how the lights will function.

  Signal Only: The lights will only flash with the signal. They will not illuminate as running light.
  
  Signal & Running Light 1.0: The lights will flash as a turn signal. At night when the running lights are activated, the lights will operate at 50% intensity for running light, 100% intensity for turn signal.
  
  Signal & Running Light 2.0: The lights will flash as a turn signal. At night when the running lights are activated, the lights will operate at 100% intensity for running light, 100% intensity for turn signal.
  
  Switchback: The lights will flash as an amber turn signal during the day. At night when the running lights are activated, the lights will operate at 100% intensity in WHITE for running light. When the turn signal is activated, the lights will operate at 100% intensity in AMBER in a flashing pattern until the turn signal is de-activated (at which point it will return to a solid white light).

• Are your mirrors plug and play?

  Power Function: If your truck was originally equipped with power mirrors the power function on our mirrors will work properly. Please note our mirrors do not support curbview assist or memory functions. They will still plug and play, but these features will not integrate properly with our mirrors.
  
  Defrost Function: If your truck was originally equipped with rear defrost the defrost function on our mirrors will work properly.
  
  Signal Function: If your truck came equipped with power adjust, the turn signal will be plug and play (even if your original mirrors didn't have it).
  
  Running Light (If Signal & Running Light or Switchback Option is Selected): You must run one wire to a running light feed (harness included). All wiring internal to the mirror is done; you just need to do the truck side wiring (instructions included).

• What color are the LED's when illuminated?

  Smoked Dotted (Amber LED)- Amber at all times
  Smoked Dotted (White LED)- White at all times
  Amber Dotted (Amber LED)- Amber at all times
  Smoked Strip- Amber if signal only or signal & running light, color changing (white running light, amber signal) if switchback
  Clear Strip- Amber if signal only or signal & running light, color changing (white running light, amber signal) if switchback
  

• How does the white rear facing light work?

  All vehicles must have the white LED light hardwired. A 9-foot jumper harness is included for each mirror.
  Most customers choose to run to the trailer backup fuse in the underhood junction block.

• Where do I enter my paint code?

  Unfortunately we do not paint the mirrors for you.
  Our paintable mirrors come with non-textured caps in a white/neutral color so they are fairly ready for paint. The caps come off of the mirrors so that you can paint them and just snap them on with no disassembly required.

• Are your mirrors power folding?

  No, unfortunately we do not offer a power fold option.

• If I purchase the Signal & Running light or switchback option, do I need to purchase the dual function harness as well?

  No, the harness is included in the price.

• Do your mirrors come level?

  Our mirrors are designed off of the OEM mirrors, and the OEM mirrors do not sit level. Many choose to level the mirrors out and there are many writeups out there on how to do it (takes about 30 minutes), however we do not endorse this as it takes the tension off the arms resulting in additional glass shake.
  If the mirrors are damaged as a result of modifications the warranty for that portion of the mirror is considered void.

• What is the difference between the low output flood and the high output spot light?

  Scroll down to see the difference; it's night and day! If you have tint on your truck the high output spot light will make the world of difference.
  Even if you don't have tint, the high output spot light is extremely convenient.
