What a Leekooluu backup camera does and whether you need one
A Leekooluu backup camera is an aftermarket camera system you mount on your vehicle's rear bumper or license plate area. When you shift into reverse, the camera sends a live video feed to a display screen mounted on your dashboard or windshield, showing you what is directly behind your vehicle. This is useful if your vehicle did not come with a factory backup camera, or if you want a second camera for a trailer or RV.
Leekooluu makes several models with different features — some are wireless, some wired, some include night vision, and some come with multiple cameras. The basic function is the same across all of them: reverse, see the camera feed, avoid obstacles or people behind you. Whether you need one depends on your vehicle's visibility, how often you back up in tight spaces, and whether you have passengers or cargo that blocks your rear view.
This guide walks you through choosing a Leekooluu model, installing it, connecting it to power, and troubleshooting common problems. It does not cover every model — Leekooluu makes dozens — but the installation steps are similar across most of them.
Key Takeaways
- Leekooluu backup cameras mount on your rear bumper or license plate and connect to a display screen that shows video when you shift into reverse.
- Wireless models are easier to install because they do not require running cables through your vehicle, but wired models are more reliable in areas with radio interference.
- Installation requires mounting the camera, running power to the display, and connecting the reverse light wire so the display turns on automatically when you shift into reverse.
- Most Leekooluu systems work in low light, but night vision quality varies by model — check the product specifications before you buy if you back up frequently in darkness.
- If the camera feed cuts out or the display does not turn on, the problem is usually a loose power connection, a blown fuse, or the reverse light wire not being connected correctly.
Wireless versus wired Leekooluu systems
Leekooluu makes both wireless and wired backup camera systems. A wireless system has a camera that transmits video to the display screen over a radio signal — no cables run between them. A wired system has a cable that connects the camera directly to the display. Each has trade-offs.
Wireless systems are faster to install because you do not have to run cables through your vehicle's interior or under the bumper. You mount the camera, mount the display, pair them together, and you are done. The downside is that wireless signals can be blocked or interrupted by metal, thick plastic, or radio interference from other devices. If you park near power lines, cell towers, or in areas with heavy radio traffic, a wireless system may drop the signal occasionally.
Wired systems are more reliable because the camera and display are connected by a physical cable — nothing can jam the signal. The downside is installation takes longer because you have to route the cable from the camera, under the bumper, through the vehicle, and to the display. If your vehicle has a lot of plastic trim or a complex bumper design, running the cable can be difficult.
For most people, a wireless Leekooluu system is the better choice because installation is simpler and signal loss is rare unless you live in an area with heavy radio interference. If you have had problems with wireless devices in your vehicle before, or if you back up in the same location every day and want zero risk of signal loss, a wired system is worth the extra installation work.
What you need before you start installing
Before you open the box, gather the tools and information you will need. You will need a screwdriver set (usually Phillips head), a wire stripper (to expose the copper on the reverse light wire), a crimper or wire nuts (to connect wires together), and a 12-volt test light or multimeter (to find the reverse light wire). Most Leekooluu kits include wire nuts and some basic connectors, but a crimper gives a more reliable connection.
You will also need to know where your vehicle's reverse light wires are located. These are usually behind the rear lights or under the rear bumper. Your vehicle's service manual or a YouTube video specific to your make and model will show you where to find them. Do not guess — connecting to the wrong wire can damage your vehicle's electrical system.
Clear a workspace where you can lay out all the parts and read the instructions without rushing. Leekooluu instructions are usually printed on a small card or available as a PDF on their website. read the PDF if you can — it is easier to read on a phone or tablet while you work.
Installing the camera on your bumper or license plate
The camera itself mounts on your rear bumper, usually above or below the license plate. Leekooluu kits come with a metal bracket and mounting hardware. Start by deciding where on your bumper the camera will sit — it should have a clear view of the ground directly behind your vehicle, with no bumper trim or lights blocking it.
If your vehicle has a license plate, the easiest mounting point is usually the license plate frame. Leekooluu makes license plate bracket kits that bolt the camera directly to the plate frame. This keeps the camera centered and at the right height. If you do not want to use the license plate frame, you can bolt the bracket to the bumper itself, but you will need to drill holes — use a drill bit slightly smaller than the bolt diameter, and wear safety glasses.
Once the bracket is bolted down, slide the camera into the bracket and tighten the adjustment screws. Point the camera straight down and slightly backward — you want to see the ground about 10 feet behind your vehicle. If the camera points too far down, you will see mostly ground. If it points too far up, you will see mostly sky. Adjust it until the view looks right, then tighten all screws firmly so vibration does not shift it while you drive.
For wired systems, this is where you also run the video cable from the camera toward the front of your vehicle. Route it along the underside of the bumper, then up into the vehicle through the nearest opening — usually where the bumper meets the body, or through a grommet hole if one exists. Avoid sharp edges and pinch points. find the cable with zip ties every 12 inches so it does not rattle.
Mounting the display screen and connecting power
The display screen usually mounts on your dashboard, windshield, or sun visor. Leekooluu kits come with a suction cup mount or an adhesive pad. If you use the suction cup, clean the windshield or dashboard with rubbing alcohol first so it sticks firmly. If you use the adhesive pad, press it down hard for 30 seconds and let the adhesive cure for an hour before you drive.
Mount the display where you can see it while driving in reverse, but not so high that it blocks your view through the windshield. Most people mount it on the lower left side of the windshield or on the dashboard to the left of the steering wheel. Make sure the cable (if wired) or the power cord (if wireless) can reach without stretching.
Next, connect power to the display. Leekooluu displays run on 12 volts, the same as your vehicle's battery. The power cord has two wires: red (positive) and black (negative, or ground). The red wire needs to connect to a 12-volt source, and the black wire needs to connect to a ground point on your vehicle's chassis.
The easiest way to power the display is to run the red wire to your vehicle's fuse box and add a new fuse tap, or to run it to the positive terminal of the battery. The black wire can connect to any bare metal on the vehicle's frame — a bolt on the dashboard, a screw on the door frame, or the negative terminal of the battery. If you are not comfortable working with your vehicle's electrical system, a car audio shop can do this part for you in about an hour.
Connecting the reverse light wire so the display turns on automatically
The display should turn on automatically when you shift into reverse, not when you turn on the ignition. To make this happen, you need to connect the display to your vehicle's reverse light wire. This wire carries 12 volts only when the transmission is in reverse.
Find the reverse light wire by locating your vehicle's rear lights. The reverse lights are usually white and sit on either side of the license plate. Behind the light assembly, you will find a connector with several wires. One of them is the reverse light wire — it is usually white or white with a stripe. Use a test light or multimeter to confirm: have someone shift the vehicle into reverse while you touch the test light to each wire. The wire that lights up is the reverse light wire.
Once you have found it, strip about half an inch of insulation from the reverse light wire and from the trigger wire on your Leekooluu display (usually a thin white or yellow wire). Twist the two bare copper ends together, then cover the connection with a wire nut or crimp connector. Wrap the connection with electrical tape for extra security. This connection tells the display to turn on whenever the vehicle is in reverse.
If you cannot find the reverse light wire or do not want to work with your vehicle's wiring, you can buy a manual switch that mounts on your dashboard. When you shift into reverse, you flip the switch to turn on the display. This is less convenient than automatic, but it works and requires no wiring.
Testing the system and troubleshooting common problems
Before you drive, test the system in your driveway. Turn on the ignition, shift into reverse, and check that the display turns on and shows a live video feed from the camera. The image should be clear, in color (if your model supports color), and show the ground directly behind your vehicle. If the display does not turn on, the problem is usually a loose power connection or a blown fuse.
If the display turns on but the camera feed is black or blank, the camera may not be getting power. Check that the camera power wire is connected firmly. If it is a wireless system, the camera and display may not be paired — most Leekooluu wireless systems pair automatically when you power them on, but some require you to press a pairing button. Check the instructions.
If the image is very dark or grainy, the camera lens may be dirty or the camera may not have enough light. Clean the camera lens with a soft cloth. If it is still dark, your model may not have night vision, or night vision may be turned off in the settings. Check the display menu — most Leekooluu displays have a brightness or night vision setting you can adjust.
If the display turns on but the image cuts out when you drive, the problem is usually a loose cable connection (for wired systems) or radio interference (for wireless systems). For wired systems, check that the video cable is fully seated in the connector at both the camera and the display. For wireless systems, try moving the display to a different location on the dashboard — sometimes a different position reduces interference.
Frequently Asked Questions
Can I use a Leekooluu backup camera on a trailer or RV?
Yes, Leekooluu makes wireless camera kits designed for trailers and RVs. The camera mounts on the back of the trailer, and the display mounts in the tow vehicle's cabin. Because the distance between camera and display is greater than on a car, make sure you buy a model rated for the distance you need — most wireless Leekooluu systems work up to 30 feet, but some go further.
What if my vehicle already has a factory backup camera?
You can still install a Leekooluu camera as a second camera, or you can use it to replace the factory camera if the factory system fails. If you want to keep both, you will need a display that can switch between two camera inputs, or two separate displays. Some newer vehicles let you add a second camera through the factory infotainment system — check your vehicle's manual.
Do I need a professional to install this?
Most people can install a Leekooluu backup camera in two to four hours with basic tools. The hardest part is usually finding and connecting the reverse light wire. If you are not comfortable working with your vehicle's electrical system, a car audio shop or mobile installer can do the work for $100 to $300, depending on your vehicle and whether the system is wired or wireless.
Will the camera work in rain or snow?
Yes, Leekooluu cameras are rated for outdoor use and work in rain and snow. The lens may get wet or covered with snow, which will blur the image, but the camera itself will not be damaged. In winter, you may need to wipe the lens clean before backing up. Some Leekooluu models include a lens heater that melts snow and ice automatically — check the product specifications if you live in a cold climate.
Can I hardwire the display to stay on all the time, not just in reverse?
Yes, you can connect the display power directly to a 12-volt source instead of to the reverse light wire. This lets you view the camera feed anytime, not just when you shift into reverse. You will need to turn the display on and off manually, or you can wire it to a switch on your dashboard. This is useful if you want to monitor a trailer or RV while parked.
