Best trailer light kits: Factors to consider

So, you’ve decided to do the safe and legal thing by getting your trailer a quality trailer light kit. Good job. However, we understand that you may not know how to go about it. Well, fret not. The tips and other information in this section will help you identify and choose the best trailer light kits for your utility trailers faster than you can say, Jack Robinson.


One of the first things you should know about trailer lights is that they will be exposed to moisture, especially if you work in wet conditions/weather or dock watercraft frequently. As a result, you should be aware that you'll need to opt for waterproof light kits if you want something that'll last a long time. The cheapest trailer light kits will include incandescent bulbs wrapped in a waterproof light pod. If you're willing to spend a little more, you will still get incandescent bulbs, but the bell jar principle will protect them from moisture this time. However, if you have deep pockets, you'll get the best that the market has to offer, which is permanently and efficiently sealed LED lights. In addition, you should also select DOT-approved lights with IP67 ratings for top-notch durability.


Like your kids’ Lego sets, trailer light kits come with lights of various shapes. In this case, the shape you choose will be determined by your trailer's frame. So, if your trailer has a rectangular frame, go for rectangular lights. Apply this rule of thumb to any other trailer frame, and Bob’s your uncle.

Light technology

When you pop open your trailer light kit, you’ll find either an LED or incandescent light bulb. Note that it isn’t some kind of raffle; you can choose whatever light bulb type you want in your trailer light kit, and we strongly suggest you go for LED lights. LED trailer lights are becoming the industry standard because they’re approximately six times more energy-efficient than incandescent lights. Because they are relatively inexpensive, incandescent bulbs are the most affordable option. However, you should be aware that they are not as durable as LED lights. Their illumination is not as efficient, as they emit light at 360° rather than the more efficient 180° illumination.

Trailer size

Your trailer’s size can also significantly influence the type of trailer light kit you choose. For example, if your trailer is wider than 80 inches, you have no choice but to select kits with clearance lights. Traffic authorities require these lights to be installed on oversized trailers, so you must ensure that it comes in your kit before buying it.

What type of lights are included in a trailer light kit?

Since you're purchasing a kit, you'll likely find a variety of lights in one package. However, we'd like to highlight some of the most important lights that every standard trailer light kit should include.

Reflectors: Reflectors, as the name suggests, reflect the lights from other light sources. They aren’t actual lights since they require no wiring to function. However, they’ll illuminate even if the other lights fail.

Brake Lights: You probably already know these as the red lights that indicate that you’ve hit the brakes. They’re highly critical since their absence may cause accidents if you suddenly stop and drivers near you have no idea. In fact, it is illegal not to use brake lights for your trailer, so ensure that they’re in the package you’re buying.

Turning Signals: These lights are typically installed on both sides of your trailer and are just as important as any other set of lights in a trailer light kit. They indicate whether you’re turning right or left, which is good for other road users to know. They also come on when you switch on your blinkers during emergencies.

Rear Identification Lights: You need rear identification lights to drive a large trailer. They typically come in a set of three red lights and are often installed right in the middle of the trailer’s rear side. Their function is to alert other road users of the presence of an oversized vehicle.

Tail Lights: Every light in the trailer light kit has a critical application in low-light conditions, but taillights are probably the most essential of them all. They’ll come on when you switch on your headlights and enable other drivers to see your position at night.

Clearance Lights: Here’s another set of lights you need if you drive a large trailer (> 80 inches wide), and they often come in two colors: red and amber. By design, red clearance lights are rear-facing, while the amber lights are forward-facing. You’ll need to install these lights on both sides of your trailer in order to alert other road users of your position.

Side Marker Lights: Like forward-facing clearance lights, side marker lights are typically amber in color. You need them to help other road users spot your trailer from an angle - like a curve in the road.
