Hypersonic 2-Pack Car Bumper Corner Antenna Poles, Green — Telescoping 11–23" with Pivoting Base

Hypersonic 2-pack adjustable bumper corner antenna poles are easy-to-fit parking markers that attach to your car’s bumper to help drivers judge corners and avoid scrapes.

These compact, telescoping marker poles mount on a horizontal bumper surface and extend from about 11" to 23" with a pivoting base so you can set the angle that’s visible from the driver’s seat. Designed for new or shorter drivers, the lightweight stainless-steel poles and plastic bases give a visual cue to the passenger-side and rear corners without changing vehicle handling. They fold away for car washes and remove easily when no longer needed.

How do these antenna poles help me park more accurately?

The poles create a visible reference point at the edge of the bumper so you can tell how close you are to curbs, other vehicles, and obstacles. That extra sightline reduces guesswork when squeezing into tight spaces.

• Visible corner marker from driver’s seat
• Telescopes 11"–23" so you can set a custom height
• Pivoting base adjusts angle for different vehicles
• Compact profile when folded for car washes

Will these fit my car and how do I install them?

These universal mounts are intended for horizontal bumper sections. The base uses a secure plastic housing that bonds best to clean, dry surfaces; no vehicle-specific parts are required. Installation is straightforward but requires surface prep and a 24-hour cure period for best adhesion.

• Fits most cars with a horizontal bumper mounting area
• Clean and dry the mounting surface before fitting
• Do not drive or wash the car for 24 hours after installation
• Fold the pole up when using automatic car washes

What materials and features should I expect from the Hypersonic bumper poles?

The poles combine stainless-steel tubing with a plastic base to balance durability and lightweight visibility. They are built to resist everyday knocks and fold away when not needed, though they are not reflective or illuminated.

• Stainless-steel extendable pole for strength and rust resistance
• Durable plastic base that pivots to set angle
• Non-illuminated top — visible day or in city lighting at night
• Adjustable length and folding function for convenience

Who is this for? These Hypersonic bumper corner markers are ideal for new drivers, people of shorter stature, or anyone who wants a simple visual aid to protect bumper corners while parking or maneuvering in tight spots. They’re a practical accessory for drivers who prefer low-tech, low-cost solutions over sensor systems — especially on older vehicles or rental cars where permanent modifications aren’t desirable. Remember to follow the installation notes closely so the mounts remain secure and fold them for car washing or storage.
