Grote SuperNova LED Side Turn Marker Light

When on the road, failure to send out signals to other drivers and pedestrians makes the roads less safe. This selfish act causes sudden and dangerous swerves, fender-benders, panic braking, or worse, fatal accidents. The advance notice that a well-functioning turn signal light can give a few seconds before an impending maneuver can save you from such mayhem.

Grote believes that when it comes to signal lighting, failure is never an option. The company never stops manufacturing innovative, long-lasting LED options to match any stop tail turn application. Its SuperNova line of lighting products is designed to deliver value and solutions that light the way most efficiently.

Grote SuperNova® Surface Mount LED Side Turn Marker Light

A part of Grote's SuperNova line of products, this turn marker light gives out bright, flashing illumination that's noticeable even from the driver's rearview mirror. The following factors make it a standout option for truck drivers, vehicle owners, and fleet operators who need a new turn signal light:

50-state legal

This SuperNova LED turn marker light meets the requirements set by each state on the use and installation of turn signals. It is fitted with high-quality LEDs that passed strict SAE J914, FMVSS 108, and California Title 13 requirements. This is ideal for delivery trucks and commercial vehicles used for interstate trips.

Metal-core circuit board

This feature enhances the dependability of a device that operates at slightly higher temperatures. On one side of the board, heat from hot-running components is absorbed; it is then transferred to the other side for heat dissipation. Metal-core circuit boards address the problem of overheating due to a large number of LEDs in devices. This improves the life span and performance of the components.

Durable screw bosses

The screw bosses of the SuperNova LED turn marker light are strong enough to withstand screw torque without developing cracks. These bosses aren't too thick, so surface sinks, voids in the plastic, and other defects are avoided.

Polycarbonate lens

Lightweight and thin, the polycarbonate lens fitted on this SuperNova lighting component ensures excellent impact resistance. This type of lens is ten times more impact-resistant than glass lenses or plastic lenses. It is less likely to develop cracks or get shattered in low-impact collisions.

Grote’s focus on reliability and innovation is what sets it apart in the heavy-duty lighting market. The effectiveness of Grote lights continues to prove that well-designed LED solutions can deliver superior brightness, durability, and visibility for commercial vehicles on every route.

Why choose Grote?

Founded in 1901, Grote takes great pride in pioneering many industry firsts, especially in automotive lighting and plastic injection molding. The company, established by William Grote, was behind the world’s first retro-reflective reflector in 1929—a breakthrough that became the universal basis for modern automotive reflectors. Along with this reflector, Grote also released the first fully automatic plastic injection molding machine.

Three decades later, the brand expanded its list of innovations with products like the Turtle-Back Marker Lamp, the first no-splice wiring system, and the industry’s first long-lasting, repairable lamp. Over the years, Grote has remained a leader in LED technology and smart wiring systems that enhance vehicle safety and performance. Their products help give your fleet a competitive advantage by improving visibility, reducing maintenance downtime, and extending the service life of lighting components.

It was in 1989 when Grote brought the world’s first LED marker light to the market. After three years, Grote Electronics was established in Ontario, Canada, to meet the heavy truck industry’s evolving needs, focusing on high technology, long service life, and efficiency for its LED products and communications systems.

Beefing up Grote’s list of breakthroughs are the first refrigerated trailer fluorescent lamp (1998), the first HID/HIR headlamp for the heavy truck industry (2001), the first solid-state electronic turn signal switch, and the first LED license plate lamp with active reflector optics (2002).

In 2004, Grote launched the first LED forward lighting system on the road, leading the way for other manufacturers to follow. This emphasis on durability and innovation continues today through advanced LED headlight systems, such as United Pacific lighting solutions that deliver consistent visibility and performance for modern fleets.

Other factors to consider when buying a turn signal light

With the endless options available online and offline, choosing the best LED turn marker light can sometimes be an uphill task. If you are having a hard time looking for the best, here are other factors you can consider:

Plug & play installation

Save yourself some elbow grease by installing your turn signals without cutting or splicing. Go for turn signals that easily hook up to the vehicle or truck’s existing wiring. If you are upgrading the entire turn signal assembly, pick one that’s already pre-wired and assembled for easy installation.

LED light’s lifespan

You wouldn’t want to spend your hard-earned money on something that only lasts a few months. Pick an LED light that guarantees longer light hours, as these represent the number of years the light will last. When deciding which option to buy, it helps to understand how to choose the right LED lighting—factors like lumens, durability, and beam pattern all play key roles in long-term performance.

Price

The saying “you get what you pay for” holds true when buying lighting products for your rig. And when it comes to turn signals, the better the bulb, the higher the upfront cost. However, premium-quality turn signal lights are often more efficient and longer-lasting, making them less expensive to operate over time.

Truck-Lite lighting products, for instance, continue to engineer lighting systems that stand the test of time. These components feature a durable construction and cutting-edge LED technology that help reduce downtime while boosting safety and visibility on the road.

Now, if you are working on a tight budget yet still want to score a premium-quality turn signal light, you have come to the right place.
