Specs:
This red LED light serves as either a side marker light or a clearance light. The light gives your truck or trailer a distinctive look that's completely street legal. This Optronics GloLight has a unique solid light pattern when lit, so your lights stand out from the rest. Optronics GloLights are a great way to add both style and value to your truck or trailer.
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.
The long-lasting, cool-burning LEDs make this light the perfect replacement for incandescent vehicle and trailer lighting. LED lights are more efficient, use less power, and last much longer than incandescent lights.
The surface-mount technology used to construct these lights protects the LEDs from shock and vibration better than through-hole technology because the diodes are soldered directly to the surface of a printed circuit board instead of attached with wires that run through holes in the board. The result is a circuit board that is smaller yet provides more routing area and that offers superior performance, reliability, and durability.
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 light on your trailer - one as a front or rear clearance light and one as a side marker light.
This GloLight has a standard 2-prong plug as pictured above. A 2-prong pigtail with mating plug (A46PB or A49PB - sold separately) is required to connect this light to your vehicle or trailer. An optional mounting bracket is also available (BK5557GB - sold separately) to make it easier to mount the light on your trailer.
Recessed-mount trailer lights install underneath a housing or a grommet (A54GB - sold separately). These lights will extend into the mounting surface and require that a hole be cut into your trailer.

Today, we're reviewing part number MCL155RB from Optronics. This is their GloLight, sealed, two inch,round trailer,LED clearance, and side marker light. It has six LEDs,whichare also called diodes, and so you get plenty of light out of this. It's three quarters of an inch deep this way and two inches across, two inch diameter that way. The LEDs will burn thousands of hours. They burn coolly so you won't hurt your fingers when you touch it.
There are no filaments to break, no bulbs to burn out or to be replaced. It also runs more efficiently and you get brighter light with less power. The housing is sealed and water-proof and this flushmount. In order to mount it, you do need a grommet, a two inch grommet and if you don't have one, Etrailer does offer this one. This is the Optronics 2-inch ground grommet flush mount, part number A54GB, that is sold separately. The light pops right in.
It is tight when it's new, so it's difficult to insert it completely during a brief demo, but it's not that hard to get in when you give it a little umph. When it is inserted completely, you do get a flush mount. The back of the grommet is open so you have clear access to your plugs. Let me put the grommet aside. You also need a two wire pigtail plug to install this light.
If you don't have one, Etrailer has this Optronics2-Wire Pigtail Plug sold separately. This is part number A46PB. I'm going to plug this in to the light. There, that's in there pretty good. We are going to use a portable power source today to demonstrate the light. First, I'm going to connect the white wire.
This is your ground. It has a ring terminal and it gets installed on a clean unpainted metal surface. The black wire is your 12 volt. Now we can turn off our overhead light, and you'll see how brightly that shines. Now this has a unique bull's eye design when it's lighted, and you can see, it has six rings that go around the center. That's your bull's eye design and it is proprietary to Optronics. You see how brightly that shines. It's a very powerful light. Now we can turn our overhead lights back on. I'll turn off the power. This light does meet all the automotive lighting requirements of the Department of Transportation and there is a lifetime warranty on the LEDs, and that's it for part number MCL155RB, the Optronics GloLight, sealed, two inch, round trailer, LED clearance, and side marker lights. .
Great service.
