Description
Product Overview
The Grote 4″ Dual‑System Backup Lamp is engineered for durability and performance. Constructed from high‑impact polycarbonate, the clear lens resists cracking and yellowing while delivering crisp light output. The patented Torsion Mount II gel‑mount cradle secures the bulb and creates a hermetic seal between lens and housing, protecting against moisture and vibration. Rated at 40 watts, this rear‑mounted unit meets OEM specifications for a wide range of cars and light trucks. Dimensions are compact at 4 x 4 x 2 inches, weighing just 3.87 ounces, making it an ideal replacement without added bulk.
Usage
Designed for everyday drivers, fleet managers, and automotive service professionals, this backup lamp excels in city traffic, parking structures, and rural roads where clear rear visibility is critical. Its clear lens ensures the red warning light is unmistakable, enhancing safety during reverse maneuvers. Installation requires no drilling or wiring modifications—simply bolt the unit into the existing rear light housing. The lamp’s robust construction also suits harsh climates, resisting temperature extremes and road salt exposure.

FAQ
Is this lamp compatible with all vehicle makes?
The lamp conforms to the standard 4‑inch rear backup light size used by most cars and light trucks. Verify the mounting bracket on your vehicle matches the bolt pattern; otherwise, a simple adapter may be required.
Do I need to replace the bulb separately?
The unit ships with a pre‑installed bulb secured in the Torsion Mount II cradle. No additional bulbs are needed for installation.
How does the hermetic seal improve performance?
The seal prevents water, dust, and road debris from entering the housing, which can cause corrosion or dimming. This extends the lamp’s service life and maintains consistent brightness.
Can I install this lamp myself?
Yes. The lamp is designed for a bolt‑on installation with basic hand tools. Remove the old unit, align the new lamp’s mounting holes, and secure with the provided bolts.
What warranty does Grote offer?
