Optronics MCL78 Series Identification Light Bar Dimensions


Sonically Sealed, Waterproof Trailer Light

The waterproof construction of this light makes it ideal for use on trailers that may be submerged, like a boat trailer. The housing and lens are sonically sealed together to create a single unit, which means that water will not get into the light and damage the diodes or circuit board.


P2-Rated Lights

Diagram of light spread for P2 rated light

A P2-rated light produces a 45-degree angle of light to either side of its centerline for a total of 90 degrees of coverage. This beam pattern can be seen straight on, but it cannot be seen clearly from the side. So this type of light can be used as either a side marker light or a clearance light, but it cannot function as both. If you need both functions, then you must install 2 separate lights on your trailer - one as a front or rear clearance light and one as a side marker light.

This is a great light bar - I always go with LED when replacing any exterior lights on our trucks. This one looks nice and the three red LED's are good and bright!

I made this purchase for my son's boat trailer. I ordered on the Monday before Thanksgiving and it arrived the day before. My son was so excited he went out and hooked it up to his truck battery to show us how bright it was. He is very pleased!

See what our Experts say about this Optronics Trailer Lights

  • Recommended Trailer One Piece Identification Light for Trailers Over 80 Inches Wide
    If you need a three light LED bar like you are describing I recommend the # MCL78RB or the # MCL98RB. As for if the legality of the solid # STL69RRXB light bar, I totally agree with you it's not worth the ticket, that being said you will need to contact the Florida DOT, because I was not able to find any information regarding this on their website. I have linked our help article on trailer lighting and regulations as well as the clearance LED ID bars for your convenience.

  • Amber Light Bar About 16 Inches Long for Trailer Clearance Light
    We don't have an amber colored light that's exactly like the # MCL78RB you referenced. The closest I have is the Peterson Mini Identification Trailer Light Bar item # 427800, which measures 16-5/8" long and mounts on 16-1/8" centers. Note that this is also an incandescent light, not LED.

  • Can Optronics Identification LED Light Bar MCL78RB be Used in Place of Peterson Light 150-3
    Yes! You can use LED light bar # MCL78RB in place of the Peterson 3-light ID light bar that you have now. I have included a link to a video review of this light bar for you.

  • Replacement LED Light Recommendations For Trailer
    For a grommet mount red 2 inch clearance light I recommend part # MCL55R1224B. This light uses a 2-wire pigtail, part # A46PB for installation. If you need amber, you would order part # MCL55A1224B. Installed without a grommet, these lights measure 2 inches diameter x 1 inch deep. You can use the 2 inch grommet part # A54GB for this light for a flush mount. It would require a 2-5/16 inch mounting hole. The tail lights I recommend are the Optronics GLOLight LED Stop/Turn/Tail Light, part...

  • Matching Horse Trailer Clearance Lights and Light Bar
    I think that your selection of light bar # MCL78RB and clearance light # MCL66RB will look could together. Since the clearance lights get screwed onto a surface you shouldn't have a problem with them getting knocked off. I have linked videos on each of these lights for you.

  • How To Use the Identification Light Bar MCL78RB As a Third Brake Light
    Yes, the Identification Light Bar part # MCL78RB will work as a third brake light. However, you will likely need to separate the stop and turn signal circuit before you power the light or else it would flash with the turn signals as well. The Pacer Performance 3rd Brake Light Logic Module part # PP20-702 however will solve this problem. I have attached a wiring diagram of the module for you as well. The green wire on this module will go to the black wire on the light.
