PC-Rated Lights

Diagram of light spread for PC rated light

A PC-rated light produces a 90-degree angle of light to either side of its centerline for a total of 180 degrees of coverage. This beam pattern can be clearly seen when you are standing directly in front of the light, as well as when you are standing on either side of the light. When properly installed, this type of light can function as both a front clearance light and a side marker light or as a rear clearance light and side marker light.

Do you have a question about this Trailer Light?
  • Recommended Replacement Light/Lens for an Older Reflect-O-Lite 400
    the Reflect-O-Lite 400 light has been discontinued for quite a while so there isn't going to be an exact replacement. Instead, the closest replacement lens we have is the Replacement Amber Lens for Optronics MC66 Series Clearance or Side Marker Trailer Light # A66AB or the Replacement Red Lens for Optronics MC66RB Clearance or SIde Marker Light # A66RB. Both of these lenses measure 4" long x 2" tall x 7/8" deep, and is made of acrylic. There's no guarantee it'll be compatible with your...

  • Replacing Incandescent Trailer Lights with LED Equivalents
    There is no specific preparation procedure required to change over your trailer's lighting from standard incandescent fixtures to the brighter, cooler-operating and more efficient LED types available now. LED lighting is a great way to both improve trailer visibility and reduce power demand on your tow vehicle's wiring system. While you are going through this conversion it is a good idea to take a thorough look at your trailer's connector and wiring, from the 4-pole (or 7-way) at the trailer...

  • Clearance Trailer Lights With Replaceable Lens Recommendation
    We do have clearance lights that may work for you. The clearance lights we offer come in amber or red and we have either 1 or 2 bulb units. You mentioned you like the 2-bulb feature on some clearance lights. I recommend part # MC66RB. This light comes with 2 incandescent bulbs and has a red lens. The amber version of this light is part # MC66AB. Both of these lights use the replacement bulbs, part # A194B. These are push-in bulbs. The replacement lens for the red light assembly is part...

  • Does Optronics # MC66RB Incandescent Trailer Clearance/ Side Market Lamp Include Bulbs
    The Optronics # MC66RB Trailer Clearance/Side Marker Light does indeed include bulbs. Optronics also offers a similar LED lamp, part # MCL31RB. LED lamps draw a fraction of the power of incandescent bulbs, and will last considerably longer.

  • Can Optronics Trailer Light # MC66RB Be Used as a Clearance Light on a 1976 Starcraft Trailer
    The Optronics trailer light, # MC66RB, can be used as a clearance light. You would need to tap into the running light circuit on the trailer wiring. You can do this anywhere along the tail light wire so if you wanted to mount it near the tail light you could do so. The white wire will need to be grounded to the trailer frame. I have included a link to a video review of this light for you.
