With everyone looking to save more money when purchasing replacement parts for their vehicle we've seen more information being published online listing who the original manufacturer is for parts.  For example cab marker lights are typically manufacturer by Truck-Lite or Grote.  However Truck-Lite and Grote sell these lights to the OEM's (GMC, Ford, Chrysler, etc..)  These OEM's frequently repackage the product and sell the light using their own part number.  Frequently the OEM part number costs more. 
How to find out who manufacturers your light:

Inspect the light lens or mounting for information

• "Truck-Lite" and "Signal Stat" can be purchase directly from Truck-Lite distributors
• "Grote" lights can be purchased from Grote Light distributors
• The light also may say  "Model 10" or a variation of this, contact a Truck-Lite or Grote distributor for help in finding your light.
