When you're out on the road, you want to tow your trailer with peace of mind. In order to be seen and recognized by other folks who share the road with you is as just as important as may be costly if ignored. Having bright lighting is crucial to visibility and your safety. Not just your semi truck requires to be lit up properly, so does your trailer in order to meet the USA standards such as SAE, NHTSA and FMVSS 108. All trailers need to have brake lamps, tail lights, turn signals as well as reflectors. Light requirements for your trailer may vary. It depends on its length, width, and GVWR (Gross Vehicle Weight Rating). So you may also need additional lighting, reflectors and even reflective conspicuity tape to stay on the legal side and be more visible.

Having working lights plugged into your trailer and working in unison with your semi truck's lights equals safe, legal on-road towing experience. Just like the lights on your semi truck, you need to keep your trailer lights in tip-top working order because they're indispensable means of communication between you and other motorists as well as folks that cross the road. This is vitally important as nobody can predict what you're going to do next. When you drive down the road, change lanes, back up, or do any other maneuvers, trailer lights should provide the illumination needed to make everybody aware of your vehicle's presence and intentions. Whether you have burnt out light bulbs, damaged lenses, or malfunctioning lights, replace them with same-as-original lights or upgrade to LEDs to maximize your visibility and safety.

On our digital shelves, we handpick a comprehensive selection of bright, efficient and long-lived trailer lights in a variety of styles, shapes, and sizes. We carry everything from tail lights and turn signals to clearance lights, side markers and reverse lights to tow and submersible trailer lights. Choose from round, oval and rectangular shapes. You'll also find necessary wiring harnesses, light modules, grommets, plugs, mounting brackets, and anything in between to get your trailer lighting up and running in no time flat and for years to come. All products are designed to provide reliable performance without flickering or dimming.

Running lights on your trailer must be on in low-lit conditions. Tail lights and marker lights on the rear are required to be red while markers on the front and sides are required to be amber. This is done so that motorists who see your trailer from the side can indicate its overall length when they're too far to light it up with their headlights. Reverse lights are white lights located n the rear of your trailer used to warn others that you're going to move backwards. Back up lights help make this tricky maneuver easier and safer by providing extra illumination behind your towed vehicle. Plus, your trailer must have a white license plate light to be visible and stay legal.

When it comes to safety, trailer brake lamps and turn signals are one of the most important lights as they alert others that you're about to change directions or bring your vehicle to a stop. Rarely unlike on cars, amber or yellow turn signals are rarely found on trailers since most of them use combination lights that usually consist of a single, two-element lamp and can function as tail and brake lamps and turn signals. One filament illuminates when the running lights are one, and another one emitting a brighter light lights up when braking and blinks when you're going to corner. Your trailer is also required to be equipped with red reflectors at the rear and amber reflectors at sides to reflect light and aid visibility.

In our online store, you'll find trailer light assemblies as well as wiring for all-size trailers. Trailer lamps available as single units as well as kits including basic lights to stay legal. Plus, we offer multi-functional lamps that act as stop, tail, turn and reverse lights. You can also equip your trailer with a tow light bar or go with magnetic trailer tow lights in the case of non-functioning trailer lights and make it safe and legal for on-road towing. They're made to reproduce the performance of your semi truck's lamps on your trailer: the two red lamps function as stop, tail, and turn signals. Controlled from the comfort of the cab of your semi truck via a wireless remote, tow lamps offer superior visibility along with versatility of placement. And if you have a boat trailer, consider installing submersible lights featuring a drain hole to withstand repeated dunking when you put your vessel into water. So, go with top-grade lighting products to get back you trailer's light system back to its tip-top condition or choose brighter, more efficient and longer-lasting trailer LED lights. Most of the LED lights we offer have water-resistant and dustproof sonically sealed lenses and housings engineered to stand up to harsh weather conditions and resist shock and vibration, while providing high visibility to promote safer towing at night and in inclement weather.
