🛠️ Why the 175 Matters

The 175 is the heaviest‑duty flasher in Signal‑Stat’s lineup:

  • 160 — Standard heavy‑duty

  • 175 — High‑load heavy‑duty (your unit)

  • 536 — Ideal‑equivalent heavy‑duty

  • 552 — Automotive heavy‑duty standard

The DOT marking (DOT 108a) indicates it meets federal lighting equipment standards — a requirement for commercial vehicles.

Collectors value the 175 because:

  • It’s less common than 552‑series flashers

  • It’s tied to commercial/fleet history

  • DOT‑marked packaging is rare

  • NOS boxed units are increasingly scarce
