Optronics Dome Light Dimensional Diagram

Need extra light over your camper kitchen sink for when you do the dishes? Or perhaps you need to upgrade the dim, old lights in your enclosed car hauler? This dome light has warm white LEDs that give you brighter light underneath a kitchen cabinet, in a walkway, above a shower stall, or inside a small hunting cabin.

Optronics Dome LEDs

LEDs are more energy efficient, last longer, and burn brighter than lights with incandescent bulbs. You won't have to worry about replacing bulbs that have brittle filaments. And because LEDs draw minimal power, the light won't drain your battery, overload your circuits, or produce too much heat.

Raw Lumens vs. Effective Lumens

Lumens are utilized to measure the actual amount of light that you can see and use from a light source. If you need a super bright light for a workspace, you will want to go with a light that has a higher lumen count. If you want a softer glow in an RV living space, you should go with a light that has a lower lumen count.

Light sources typically have 2 different kinds of lumens: raw and effective. Raw lumens represent the natural amount of light that a manufacturer says their light fixtures can produce. Effective lumens, on the other hand, represent the usable brightness of the entire light assembly, including the drive method or any lenses or reflectors.

Surface-Mount, Bolt-On Installation is Easy

Optronics Dome Light Installed

This surface-mount dome light is incredibly easy to install as an upgrade or direct replacement of your existing light. To access the bolt holes, pull the lenses up and away from the housing. Do not use any tools to remove the lenses, as they will crack. Then, using hardware (not included), bolt the housing onto the ceiling, wall, or cabinet before re-installing the lenses. The light has a 2-wire design that hooks up to ground (white wire) and power (black wire). Once you're finished, you can then turn the lights on and off using the integrated toggle switch in the center of the light. And if you want to be able to control the brightness of the light, you can connect it to an LED-compatible dimmer switch (not included).

I am sorry that this arrived in this condition. We are currently sending this information over to our shipping department for them to do better in the future. Our customer service department will be getting in touch with you soon.


Bought these lights to replace all the light fixtures in my 30 foot coachman trailer. The bulb fixtures were very hot and burning out the switches. These were an exact replacement. Easy to install, more light output, run very cool,price is great and fast shipping.Have had installed for 1 year and no problems. Very happy with these lights.bought 8 double and 2 single


Easy direct replacement, nice light quality and distribution, bright without prismatic colors. Lens covers were difficult to remove (necessary to access the screws to install). Otherwise, so far so good.



The lights seem to work well. Brightness and light output is good. My complaint is the lenses - which are not smooth, but have rounded ridges for strength? - act as a prism and project a variety of colors on the walls. This is distracting, at the least, and irritating. I ended up pulling the covers off, leaving the LED panels exposed so that we have plain, unfiltered light in the camper. I would like to have lenses that just let unrefracted light through.


This puts all my old lights to shame. Brighter and more energy efficient. (savings)
Now I'm considering replacing others that don't need to be replaced because I'll need less of them on to light my camper interior.
Easy order, quick delivery. If i need anything else for my trailer and etrailer had it, I'm ordering it from here.


I am well pleased with LED light upgrade. They are bright and are very easy to install. they are great buy.

Alonzo J.


They have been working great. Very good product


Great replacement light. Bright and plenty of wire for an easy install. These were not as long as my old lights so I did have 2 screws holes that showed after I installed these but that didn't bother me.


work nice, have gone though most of my older camper and cargo trailer with this model and single side version, I like the warmer white ones not as much of a blueish light, much brighter than traditional dome light bulbs.

sometimes the flicker a little when running off vehicle, but probably slight voltage fluctuation, also I've found they don't work with some switching mode power supplies but will work fine off batteries/clean DC


Nice lights, well made and easy to install and get hooked up. I thought they would be a brighter white than what they are but they still produce plenty of usable light to be able to see well.


Great product and etrailer quick tracking and delivery. Installed and now we can see with low consumption led lighting.


This light fixture went into bathroom above medicine cabinet. It puts out great light. Also does not put out heat.


Very nice product for a very low price. I think these are the best buy in trailer lights. They're good enough that I cancelled my plans to install a couple of 4ft strip lights.

Brightness - very good, a pair fully and easily light up the interior of my 8.5x20 enclosed trailer. It helps that I have gloss white walls and ceiling. For a trailer with a plywood interior, I would probably go with 3 of these on the ceiling. If you need detailed task lighting, you might consider using 4 of these (two at the ends of the trailer and two spaced out between front and back). That would give an enormous amount of light thruout the interior.

Installation: very easy. The covers come off easily if you use a blunt tool and push on the cover "slots" to ease the lens off. I used the blunt handle of a trim removal tool, but a piece of wood dowl would work fine as well, Even a screwdriver might be fine if you were really careful with it. The lenses are on tight but apply firm pressure an the lens will slide loose.

The lights have 8 mounting holes but you really only need to use 4. This makes it easy because you just pick the holes that are most convenient to use (I put a pair into the aluminum header rail in my trailer ceiling).

Don't forget that white is ground and black is power. I grounded the lights by crimping a small ring terminal on the white lead and putting it over one of the mounting screws.



I compared these with the lights in many other trailers and no question these are the best value in trailer interior lighting. There are better lights but at more than 5x the price. Quite a few friends who saw these in my trailer have bought these to replace their existing lights.


I changed out 7 double and 5 single lights to these LED lights in our 2009 Wildwood Bunkhouse. They are excellent lights and nicely brighter than the originals (many of which were beginning to melt the lenses).

I noted in the reviews of the trouble getting the lenses off for mounting. I had all 19 lenses off in less than 5 minutes. Very simple. Just used a small wooden dowel (diameter of a pencil) with the end shapped square and placed in the small notch in the lense and gave a firm tap with a small hammer. Tap one side then the other and they are off. I rigged up a stop for the light on the camper table but could have used a shallow drawer or some such.



Lights have worked out great. The battery power supply fan never turns of now, but did originally when about 4 old lights were on. I am thinking of replacing the last two, that I thought last year would not be used much.


We all our light fixtures in our 28 ft Winnebago with these LED dome lights, Our previous ones were not LED, and after 10 years, the plastic crumbled. These dome lights are awesome, simple to install, and though a tiny bit more narrow than the old dome lights, look fine mounted on the ceiling.
Etrailer got them to us in a record number of days, well packed. When we were unsure which to order, their personnel were excellent at answering. Their website is also great to use. Love that you can put in the make, model and year of your RV, and it tells you what will work. AWESOME!!! We will order with you in the future. Thank you.


This LED light corrected the problem that I had with OEM lights in my 2014 travel trailer where RFI from the lights were causing interference on broadcast television. Of course I have other lights that need replacement, but this is a solution. Attached photo is for the single head light which also had the same problem.

David W.


problem solved



Still pleased with this light.


I installed these lights every 4 feet in my new enclosed car hauler and boy to they light things up! With no windows in the trailer and the door closed it's completely dark in there and the one tiny light supplied with the trailer was not going to do it.



Lights work great. I installed a master switch right by the door and when I enter I can light up the entire trailer. A million times better than the single light that came with the trailer.


Replaced an old closet light in my motorhome - easy changeout - much more light now!


Wow! These lights are a 1000% improvement! My trailer had 2 old school lights that didn't produce any light at all (had to use a flashlight). These are Exactly what I was looking for. In fact I liked them so much I ordered 2 more for my oldest sons trailer too. And super fast shipping!!!

Bobby M.


Still working great!


Very pleased with these replacement lights. Would recommend to anyone looking to upgrade to LED lights. Excellent quality and value.


the overhead lights were as advertised
RV much brighter on the inside with the new lights installed



For they past year the optics overhead lighting has worked great


Replaced failed unit over my coffee shelf, definetely awesome.



working fine


Not bright enough. I just went with a battery powered flood light


These lights are excellent. I replaced the incandescents in my pop-up camper with them. The are way brighter and will save power when running on battery. I also put the dual version in the center for even more light. They are a little shorter than the ones I took out, so your wiremold could be a little short. That wasn't the case with mine because of the center light. I just had to remove and cut a couple pieces to fit. I highly recommend these as an upgrade to your camper interior lights.

Happy Camping!


Love these lights! They're so bright. We needed better lighting in the kitchen area and these are fantastic. Plus they don't get hot and brown out. I highly recommend these lights!

Connie P.


The light is amazing. We love the brightness.


The best led lights ever. Very bright, great for reading, doing puzzles, or whatever.
Not the same size as your original, I bought some plastic plugs from Hobby Lobby to fill holes that exposed on my ceiling. Looks good.
Easy installation snip 2 wires, scotch clip the the white @ black wires, turn on the power. Perfection


Quick order. Easy to purchase from, will use again.

  • One LED Strip of RVILL34 Dimmer Than The Other
    According to Optronics, having one strip of LED's on their # RVILL34 means that the lamp is defective and would need to be replaced. The good news is that Optronics offers a lifetime warranty on the LED's, so you'd just need to contact the folks you purchased it from for a warranty replacement.

  • Recommended LED Lighting for Interior of 2006 Ex-Ambulance Cube Van for Dog Grooming Business
    To ensure you have enough light, I recommend the Optronics LED RV Interior Light with Switch - 18 Diode - Surface Mount - White Housing # RVILL34. This light has a 920 Lumen rating with 815 effective lumen output. This is brighter than most LED lights and similar to a 60W incandescent light bulb. Just a couple of these would give you more than adequate light with less shadows.

  • Why Does Lumens Rating of Interior Light RVILL34 Seem High
    Lumens are a funny rating actually. Since Lumens is more about the visibility of the light at a distance they really aren't a great way to describe the amount of light provided for illumination. The # RVILL34 does have a very high Lumen rating at 930 but that is linked to the fact that the lights are LED and the light panels in the light are pretty large. This is a very bright light though, check out the review video I attached.

  • Do Horse Trailer Interior Lights Require a Fuse be Installed on the Circuit
    For an interior light on a horse trailer most would not install a fuse on the trailer side. The circuits are already protected by fuses on the vehicle side so it would be a bit redundant. If you have the 12 volt power ran to the trailer and ready to be wired to a light you are on the right track and would just need to install and wire a new set of lights. The most popular option we have that would work well is the part # RVILL34. This uses LEDs for illumination so it doesn't draw hardly...

  • How to Wire 2-Wire LED Lights to Enclosed Trailer
    No problem. If your existing trailer interior lights use a 1-wire hookup this means they use their mounting hardware to make the ground connection and the single lead is the +12V feed. Adding more high-efficiency LED lights with 2 wires will only require you to run that separate (white) ground wire to a suitable metal surface on the trailer (such as the surface the existing light are mounted to).

  • LED Interior Trailer Light Recommendation for Enclosed Trailer
    LED interior lights can be pretty easily installed on your trailer that will be powered by the trailer connector's 12 volt power circuit. The part # RVILL34 is a pretty common LED setup that would work well. It has a switch built in and two LED panels to produce light for the trailer. As long as your trailer is you might go with at least two depending on how bright you need it to be. The 12 volt power circuit of your 7-way is the 1:00 position of the 7-way.

  • What's a Good Light for Above my RV Shower Stall?
    Yes the Optronics LED RV Interior Double Dome Light with Switch part # RVILL34 would be a great light to have above your shower stall. I like the really bright and clear light that this on produces. Since it is LED you won't have to worry about changing any bulbs and the LEDs tend to last much longer that he standard incandescent and don't draw as much power. This would be a solid choice. I linked a video of Hayden showing the install process and how it works below. Happy Camping!

Once the lenses are removed you will have access to the LED boards and the mounting screws holding the light assembly to the surface its mounted to.

Clearly you have 12 volts present at the wiring, and if an incandescent bulb can be illuminated there then there is no reason the # RVILL34 shouldn't work unless there was an error in the wiring.

  • Will the Optronics LED RV Interior Double Dome Light Work With Both 110 VAC and 12 VDC

  • How Should I Wire a LED Light I want to Add to my Camper
    The Optronics LED RV Interior Double Dome Light with Switch part # RVILL34 as you said only requires two connections. White going to ground and black to power. I would switch my power wire connection to where it is connected after the switch on the existing light. This will ensure that both lights get power at the same time rather than them getting it separately.

  • Does Optronics LED RV Interior Light with Switch RVILL34 Run on AC or DC Power
    I'd imagine that your interior lights are currently powered by either AC or DC power and when the camper switches from 120 AC to 12 DC there is actually a converter in play that keeps the power source the same voltage for your lights as this is a common setup. If the lights you have currently are 12 volt then the Optronics LED RV Interior Light with Switch # RVILL34 would work well as a replacement. Nearly all campers use 12 volt lighting like this.
