Nilight Whip Light Spring Mount Base 2PCS — Heavy-Duty Barrel Spring Mount, Carbon Steel Black

Nilight 2PCS Heavy Duty Barrel Spring Mounting Base provides a rugged, spring-loaded foundation to protect and secure whip lights or CB antennas on off-road and utility vehicles.

These two spring bases are engineered to absorb impacts and reduce breakage of whip-mounted lights and antennas while offering broad vehicle compatibility. Constructed from high-strength carbon steel with black powder-coat and stainless fasteners, the mounts resist corrosion and flex under strain. They are designed for screw shafts with diameters between 0.448" and 0.465" and require a M12*30 thread hole or 0.47" mounting opening on the vehicle or bracket. The package includes two spring bases, two stainless nuts, and four stainless washers for quick installation.

How does this spring base protect whip lights and antennas?

The barrel spring design disperses impact forces by bending rather than transmitting shock to the light or antenna, reducing the chance of snapping during collisions with low branches, tight tunnels, or sudden crosswinds. The flexible spring absorbs concentrated loads so the attached accessory survives impacts.

• Spring structure flexes to dissipate energy and prevent breakage.
• Strong carbon steel body resists deformation under load.
• Powder coating and stainless hardware guard against rust after repeated use.

Will these bases fit my whip light or CB antenna?

They are compatible with whip lights, fiberglass CB antennas, center-load antennas and similar accessories that use a screw shaft between 0.448" and 0.465" in diameter. Note: these mounts fit non-spring models of Nilight whip lights only.

• Accepts screw diameters: minimum 0.448"; maximum 0.465".
• Requires a mounting hole or bracket with roughly 0.47" clearance and an M12*30 thread on the base.
• Confirm your accessory’s shaft size before ordering to ensure fit.

How durable and weather-resistant are these mounting bases?

Manufactured from high-strength carbon steel, the mounts are built to withstand off-road vibration and shock without bending. A thick black powder-coat finish plus included stainless steel nuts and washers provide protection against rust, dust, and moisture for long-term outdoor use.

• Carbon steel construction for structural strength and shock resistance.
• Thickened powder coating reduces corrosion and simplifies cleaning.
• Stainless steel fasteners included to prevent galvanic rust.

How easy is installation and what vehicles are these compatible with?

Installation is straightforward and typically takes under 10 minutes with the provided hardware. The bases suit many vehicle types when the mounting dimensions match—UTVs, ATVs, trucks, golf carts, dune buggies and similar platforms.

• Package includes 2 spring bases, 2 stainless nuts, and 4 stainless washers.
• Fits vehicles or brackets with a 0.47" mounting hole and M12*30 thread mounting point.
• Commonly used on Can-Am, go-karts, sand rails, ambulances, pilot cars, and more.

Who is this for? If you own whip lights or CB/fiberglass antennas mounted on off-road, utility, or fleet vehicles and want a stronger, more flexible base to reduce breakage, these Nilight spring mounting bases are a practical upgrade. They suit hobbyists and professionals who need quick installation, corrosion resistance, and proven impact absorption—just verify your shaft diameter and mounting hole size before purchase.
