Optronics MC21 Series Marker Clearance Light Dimensions

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.

Video Transcript for Optronics Trailer Lights - Clearance Lights - MC21AS Review

Today we're going to be taking a look at part number MC21AS. This is the Optronics Beehive Sidemarker and Clearance light with the mounting bracket already attached to it. It's going to feature a heavy duty black enamel steel housing. The mounting bracket and the hardware are both included. This unit is designed for 12 volt systems. It's going to feature a single wire design for power and then the grounding function is going to be accomplished through the mounting hardware.

This is department of transportation approved. We're going to go ahead and take some time just to go over a few basic measurements. The distance that we have between our mounting holes, measuring center on center, it's going to measure 3/4 of an inch. The overall length, measuring from the front of the lens to the back of the bracket, that's going to give us a measurement of about 4 1/16 of an inch. The height, that's going to give us a measurement of 2 9/16 of an inch and then from the front of the lens to the back of the housing, that's going to give us a measurement of about 2 5/16 of an inch. We're going to go and hook it up to our external power source. That way you can see what it looks like with power running to it.

So, I'm just gonna go ahead and connect our power wire and since this grounds through the nine hardware inaudible 00:01:26 I'm just gonna attach our ground wire to the mounting bracket. So you can see here it sends out a really nice consistent signal. The lens allows a lot of light to come through. It's going to contain an incandescent bulb system, amber lens, and it's got that beehive design, so it really does allow a lot of light to come through. And the lens allows the light to be distributed pretty evenly. That's going to do it for today's review of part number MC21AS.

This is the Optronics Beehive Sidemarker and Clearance light with the mounting bracket and the included hardware. .

This is more a review of e-trailer than this particular product. I was looking for some amber/orange bezels to fit over existing white LEDs on my motorcycle etrailer site was easy to search, price was reasonable and being in the StL area, delivery was quick. I've used them several times in the past and always good. 335570


Comments

These worked great for what I needed. Not being sealed units worked for me since I wanted just the beehive lens which was surprisingly hard to find. They have spent a year down low on the bike taking bugs and all manner of road debris with no problems.

I had previsly installed signal lights on my Arctic Cat Prowler UTV using the only red and amber beehive lights I could find. They were the new style sealed units which were very dim. I searched the internet over the last few years looking for the old style with the spring wire that holds the lens and a changeable bulb.Then I came across eTrailer and there they were. I called and what I saw was confirmed so I ordered 2 red and 2 amber.2 days later they were delivered.Great service,thank you! Robert MacRae 71382

Do you have a question about this Trailer Light?


  • What Type of Bulb Does the Beehive Side Marker # MC21AS Have In It
  • The type of bulb that is in the Beehive Side Marker # MC21AS is an A-67 bulb. We don't carry that style of bulb.

  • Tail Lights with Separate Amber Turn Signals for a Motorcycle Trailer
  • We have lights that can have separate brake light/turn signal functions but they are large double and triple tail lights designed for RVs and would probably not be the best option for a motorcycle trailer. One possible solution is to use a set of regular tail lights such as # TL29BK, and then separate amber turn signals that are DOT approved as turn signals (the amber lights we have are DOT approved as trailer side marker or clearance lights). Although a beehive style light such as...

  • Can LED-type Round Beehive Clearance Lights Fit in Place of Incandescent Type
  • The Optronics Beehive Side Marker and Clearance Light # MC21AS that you referenced uses a single-wire electrical connection since it grounds through its mounting bracket. The two LED-type round amber beehive lights we offer, which can be seen on the linked page, use a 2-wire hookup and also are flush-mount types that use a rubber grommet for installation. These cannot be installed in the bracket-mount fixture that holds the lens with a metal ring. LED lights are offered in flush-mount...

  • Red Beehive Marker And Clearance Light In 2-1/2 Inch Round
  • The Beehive Side Marker and Clearance Light w/ Mounting Bracket, 1 Wire - Amber # MC21AS is the only light that comes with the bracket. If you want a red light in the same size, we have the Sealed LED, Beehive Trailer Clearance, Side Marker Light, 2-1/2" Diameter - Red # MCL23RB that can be flush mounted using # A55GB or recess mounted using # A57GB. If you want a recessed mount, you can use the Heavy-Duty Metal Mounting Bracket for 2-1/2" Round Clearance Lights # BK55BB for these...

  • Availability of Red-Lens Beehive Side Marker and Clearance Light
  • We do offer a red-lens Beehive LED Trailer Clearance/Side Marker Light from Optronics, their part # MCL21RB. This high-efficiency LED light features 8 diodes and can be mounted using Round Grommet # A54GB and connected using Two Wire Pigtail # A46PB. We do not have the exact bracket mount light you referenced in a red version. The link at right will show you all round, red surface-mount clearance lights.
