Comparing Miro-Flex LED Trailer Side Marker Light and Mid-Ship Turn Signal OPT78FR and MCL48AB


What is the difference between the Optronics Amber LED Side Marker lights OPT78FR and MCL48AB. They both have 16 diodes and look the same but one is more expensive.


Helpful Expert Reply:

There are a few differences between the # MCL48AB and # OPT78FR. One of them being the delphi plug that comes with the # OPT78FR. this connector provides a weatherproof connection. The # MCL48AB just has the standard 3-wire pigtail.

The other difference is the rating. The # MCL48AB is P2 rated while the # OPT78FR is PC rated. Since a PC light meets all specifications of a P2 light the best choice is going to be the # OPT78FR. The PC rating means it will be visible horizontally left-right at 180 degrees. In other words the light will be visible from different angles where the P2 light only sines directly.

I have attached some review videos for your reference.
