You can find this product under 09-14 Ford F150 & 10-14 SVT Raptor LED Side Mirror Marker Lights (75-201).
Q: How do I install the LED side mirror lights?
A: First locate the reflector on your mirror
Use a flat too or flat head screwdriver to gently pry off the reflector and remove
Please note that the iJDMTOY LED light and most reflectors have a single tab but some reflectors might have 2 tabs. Some minor cutting/modification of the tab openings on the back of the mirror housing might be required if your old OEM reflector had 2 tabs
Install your new LED turn signal lights by routing the wiring to the glass/mirror side of the mirror housing.
Attach the positive and negative wires accordingly.
Clip the LED light into place.
