Frequently Asked Questions:

• How do the forward-facing lights work?

  Check out the dynamic pictures found 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 curb view 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 a rear defrost the signal will be plug and play.
  Running Light: 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 LEDs 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 a switchback
  Clear Strip- Amber if signal only or signal & running light, color-changing (white running light, amber signal) if a 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 and installed into the mirrors before they are shipped to you.

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

  Navigate to the Product Details tab to see the difference; it's night and day! If you have tint on your truck the high output spotlight will make the world of difference. Even if you don't have tint, the high output spotlight is extremely convenient.
