CE Smith Boat Trailer Parts - CE27740

  • CE Smith

Lighted guide-on posts make it easy to load your boat onto your trailer and safer to transport it at night. They attach to the rear of your trailer and extend out of the water, providing visual targets to center the boat between during loading.


  • Guideposts assist you in centering your boat as you load it onto your trailer
    • 1-1/2" Diameter, 16-gauge, pre-galvanized steel tubes are covered with 2" PVC piping for strength and durability
    • Simple installation on rear crossmember of trailer frame with included hardware
  • LED lights ease loading process and make trailer more visible at night
    • Glows amber at front, bright red at rear
    • Alerts other drivers to your position
    • Makes trailer easy to see while you are backing it up or loading your boat
    • Features 1-piece, sealed units that are shockproof and waterproof
    • Activates automatically with your trailer's tail lights
    • Longer-lasting and more energy efficient and durable than incandescent lights
  • Simple installation
    • Wires into your trailer's tail lights
  • Made in the USA


  • Quantity: 2 boat guide-ons
  • Application: trailer frames up to 3" wide x 4-1/4" tall
    • 2 Extra-long U-bolt kits (CE11416; sold separately) are required for mounting on frames up to 3" wide x 5-1/4" tall
  • Height: 40"
  • Adjustable out to 13" on each side

Note: Check with your state Department of Transportation for restrictions regarding maximum trailer width.

When your boat trailer has been backed down the ramp and is partially submerged, these 40" tall guideposts that are mounted at the rear corners of the frame will stick out of the water, giving you two highly visible targets to guide your boat between for loading. The built-in LED lights on the posts stand out at night, making it easier for you to load your boat in the dark and for other drivers to see your trailer when you're on the road. The pre-galvanized steel support posts mount horizontally on top of or below your trailer's frame rail. Just slide the posts into the boat guide supports and secure the posts so that the distance between them correctly matches the width of your boat.

Pre-Galvanized Steel

Pre-galvanized steel parts are stamped from a sheet of steel after it has already been galvanized. The edges of the pre-galvanized parts often lose their zinc coating during the stamping process. Because of the thinness of the coating less than 1 mm and the fact that the edges remain exposed, pre-galvanized parts can begin to oxidize and rust quickly, so its recommended that they be primed and painted.

Average Customer Rating:  4.8 out of 5 stars   (284 Customer Reviews)

Lighted guide-on posts make it easy to load your boat onto your trailer and safer to transport it at night. They attach to the rear of your trailer and extend out of the water, providing visual targets to center the boat between during loading.


This is great! Also - here’s the CE17720 fender all complete and installed. I like the split lighting on the poles, easy to install and much better than - at least for me - piecing together stuff from a hardware store. Worth a little extra dough for these rock solid poles!


I ordered this set of guide ons when I started redoing my boat and my summer got busy and as September rolled around I finally got them mounted and wires hooked up.
Unfortunately now it’s deer season and the boat is going into storage. Get back with me in May and I might have it in the water.


Installation of these guides was pretty simple. I did have to slide the axle forward a few inches, but that was not a big deal. They work great, are very stable, and help considerably when backing at night.

They have been great. I do have one light that’s been intermittently off, but that is probably a loose ground I can deal with.

Everything was in the box and all I need to install the lights
I hooked up the boat and the lights worked great. I think I can
Talk my friend to buy one.
Thank you for the smart crew that thought the light up.
God Bless


Arrived quickly, easy to install and looks really nice on our boat trailer for our 2021 Tahoe T16 boat.


This has made all of difference in the world. It helps with backing up since you can see the lights even if the boat and trailer are too low to be seen from the rear view mirrors. It also helps a lot at night with lining the boat up with the trailer. Before the lights were submerged so it was hard to tell where the trailer really was. Would definitely buy again!


Great product as fishing usually starts early and ends late. I know where my boat trailer is and that increases confidence when I'm towing.


the U-bolts are not big enough for a 4x7 I-frame, but I bolted the brackets directly to the frame and made it work anyways.

I also made it removable, because installed, the trailer would exceed 8.5 ft width.

One star deduction because the brackets came raw mild steel, not galvanized.


Liked one of the two of the pair. One is working great so far. One didn’t make it two hours into the first trip of pulling the boat trailer. And you can’t buy just one. You have to buy as a pair.

I reached out to the manufacturer and they suggested making sure all connections are secure as the LEDs should not be going out like that.
-- Etrailer Expert Brooke M - 07/07/2022


I do like the guide on poles, really don’t need for guide to put ski’s on bunks just love the LED’s. Easy install, took about an hour for lights and all to be completed.


Looking forward to my first use of thes Guide-Ons.


My boat is wide enough to cover my fenders. The horizontal piece does not extend out far enough to clear the side of the boat. I am trying to see if I can add a sleeve to gain more clearance. I will let you know if I solved this problem.


They are a great product. I love how they light up yellow in the front red in the back. I have no problem back my trailer up and loading my boat. They are great for the little set up that I have.


Have ordered multiple times and always gotten good products and always recieved on time with excellent customer service


Nothing wrong with the poles. Work great... the boxing is horrible. All parts are just thrown into the box, nothing is covered for shipping. Plastic tube came beat all to he'll.




Great product. I cut the plastic tubes so that the lights are at the top of the sideboards to prevent catching the docking line on them during loading. My trailer has heavy metal rectangular tubing so the supplied screw to ground the lights was not heavy enough to penetrate with the recommended drill size. I used a self drilling/tapping screw with great success.

The brackets were very well designed and hold the square tubing of the light very well.

I have been very happy with the CE Smith Boat Trailer guide-onlights. Metal parts are still shiny with no hint of rust. Lights assist in trailer placement for docking and assist trailer towing maneuvers easier to tell where the end of the trailer and boat are located relative to the towing vehicle. As you can tell, I have been very pleased with the quality and performance of the CE guide-ons with LED lights.

Good quality heavy duty abs and good quality lighting


Really like everything about this produ ct.


I'm very pleased with the lighted CE Smith guide post for my boat. There very easy to install, and the LED lights are super bright. The guidepost makes it very easy to load the boat onto the trailer keeping the boat from blowing off the trailer with the wind or the current pushing it off. Great customer service experience with E Trailer and very fast shipping. Overall giving them five stars and would definitely recommend them and we'll be using them again in the future!

Thanks, the boat strap and the lighted posts guides are still working great !
Jason T - 04/12/2018


The trailer guides I purchased were exactly what I wanted and expected. They were received in excellent condition and were mounted and working in an hour. Great service and price from eTrailer.

  • What Trailer Wiring Circuit Does the CE Smith Post-Style Guide-Ons # CE27740 Run To
    The brown wire of your trailer wiring would be the one that carries the running light circuit. That would be the correct circuit to use for powering the CE Smith Post-Style Guide-Ons # CE27740. I attached an install video for this product for you to check out as well.

  • Painting Galvanized Steel Brackets for a Boat Trailer
    First, I would prime and paint the whole bracket if for nothing else but to make sure it is all uniform. Galvanized steel is going to require certain products to be able to paint it and have the paint last. the first thing you will need to do is clean the galvanized parts with water-based cleaner/degreaser to remove any of the oily film on the parts from the galvanization process. Once clean you will need to use a water-based primer. Do not use a petroleum-based primer because the oil...

  • What Size Trailer Frames Does the CE Smith Post-Style Guide-Ons with LED Lights Fit
    Yes. The CE Smith Post-Style Guides # CE27740 are designed to work on trailer frames up to 3" wide and 4-1/4" tall, so it will work on your 1-1/2" wide and 3" tall frame.

  • How Do You Remove the Lights on the CE Smith Post-Style Guide-Ons # CE27740
    On the CE Smith Post-Style Guide-Ons # CE27740 the lights are held into the tops of the tubes with little screws. The screws would have to be removed to release the lights.

  • Why Does Running Light Circuit Get Ran to CE Smith Post-Style Guide-Ons # CE27740
    If you wired the CE Smith Post-Style Guide-Ons # CE27740 that you referenced to the stop/turn signal of your trailer wiring they would blink with the blinkers and come on with the brake lights. There's no reason you couldn't do that but as their intended purpose they wouldn't be as effective. Normally these are wired to the running light circuit so that when your tow vehicle has their head lights on (at night) the lights come on to help you guide your boat onto the trailer.

  • Can Ground Wire of CE Smith Post Guide Ons be Ran to Trailer Frame Easily
    The wiring of the CE Smith Post-Style Guide-Ons # CE27740 is a double bonded wiring setup that you would normally run back to front of trailer. Since it's double bonded though you can separate the wires from each other by pealing them away from each other and then run the ground to the trailer frame wherever works for you and then the power wire to the running light circuit and you'd be set.

  • Does the CE Smith Post Style Guide-Ons with LED Lights Come with the Lights Included
    Yes. The LED lights on the CE Smith Post-Style Guide-Ons with LED Lights for Boat Trailers - 40" Tall - 1 Pair # CE27740 are separate pieces that will require installation to the guide-on; these lights will wire into your boat trailer's tail lights. I've linked a review video of these for you to check out.

  • Can You Paint the CE Smith Post-Style Guide-Ons
    No. In most cases getting paint to stick to the galvanized steel on the CE Smith Post-Style Guide-Ons # CE27740 is not going to be possible because of the layer of zinc that's left after galvanization. I don't recommend painting them as it's most likely going to be an exercise in futility.

They both use the same type of mounting brackets that attach to the boat trailer frame.

  • Lighted Guide On Recommendation for a Boat Trailer
    We actually have a product that does exactly what you are looking to do. Check out the CE Smith Guide Ons part # CE27740. These are guide-ons that have LED lights on the tops of them for increased visibility. The PVC of this kit would be strong enough for it's intended purpose of helping guide a boat onto the trailer. As long as you aren't hitting them at too hard of angle you should be just fine. You would probably have bigger problems anyway if you were hitting these hard enough to break...

  • Shortest Available Trailer Guide-On for 2008 Bass tracker 17 .5
    The shortest set of guide-ons are the 40 inch # CE27620 that you've looked at. The nice thing about these is that they're constructed of PVC pipe, and they can be cut down further if you wish. As you can see in the video I've linked, the tops of the guide-ons don't stick up very far from the gunwales of the boat. If you were interested in the light-up guide-ons, you could use the # CE27740, and cut those down as well. If you're on a fairly tight budget, the # CE27620 would work very well...

  • Which CE Smith Post Style LED Guide-Ons To Use
    Which CE Smith Post-Style Guide-Ons with LED Lights for Boat Trailers you'll want to use depends on the height of your boat when it's sitting on the trailer. We don't have craft specific guides for this so you'll want to measure from where you want to install these on the trailer to the top of where the boat sits on it so that you make sure you get something that you can see well. For smaller bass boats that don't sit very high off the water you're typically going to use the 40" tall #...

  • Boat Trailer Guide-Ons for 18 Alumacraft Dominator on Shorelandr Trailer
    I recommend the CE Smith Post-Style Guide-Ons with LED Lights # CE27740. These will provide you with the assistance when loading in wind and current but also with visibility as the lights come in handy when it starts to get dark. This will not only help when loading the boat but also when backing up the trailer as the lights and poles offer a great reference point for seeing the back of the trailer.

If you need to have the shorter ones then you would need the kit, # CE11452-A. It might not be a bad idea to replace the brackets too. If there was enough damage to require new u-bolts then there could be unseen damage to the brackets as well.
