Frequently Asked Questions
-
How does the forward-facing light work?
Check out the dynamic pictures above for an idea of how the lights will function.
If you choose signal only it will only work as an amber signal.
If you choose switchback (amber/amber) the lights will illuminate amber in running light mode, and amber in signal mode. Further explained, if you just have the running lights on the light will be a solid amber strip. If you activate the turn signal while the running lights are on the solid amber light will turn off, and the amber light will flash. After the signal turns off the amber light will turn back on. If your running lights are off the amber signal light will flash like a normal signal.
If you choose switchback (white/amber) the lights will illuminate white in running light mode, and amber in signal mode. Further explained, if you just have the running lights on the light will be a solid white strip. If you activate the turn signal while the running lights are on the solid white light will turn off, and the amber light will flash. After the signal turns off the white light will turn back on. If your running lights are off the amber signal light will flash like a normal signal.

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 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.
- Turn Signal: If your truck came equipped turn signals the signal will be plug and play.
- Puddle Lamp: If your truck is model year 2005 or newer and originally came equipped with puddle lamp, the puddle lamp will be plug and play. 2004 trucks are not offer with puddle lamp.
- Running Lamp (Switchback Only if 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?
Signal Only - Amber
Switchback (Amber/Amber) - Amber
Switchback (White/Amber) - White for Running Light, Amber for Signal
-
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.
