Perko 1607DP0CHR Tower & Arch Light — Tri-Position All-Round, 12V, USCG Certified Under 20m (9-1607DP0CHR)

The Perko 1607DP0CHR Tower & Arch Light is a USCG-certified all-round navigation light purpose-built for T-tops, arches, and towers on power-driven vessels under 20 metres (65.6 ft.). Its tri-position design gives you three distinct operating modes from a single light — all controlled by rotating the head and locking it with the thumbscrew.

The 3/4 in. anodized aluminum pole mounts to flat, curved, or V-type surfaces using the included plastic adapters, and the base includes a notch for clean through-base wiring. Chrome finish.

Three Operating Positions

• Up (vertical): 360° all-round white navigation light — meets USCG requirements for vessels under 20m underway at night.
• Down: Cockpit courtesy light — illuminates the cockpit or deck area without projecting forward.
• Forward: Light faces forward and out of the way — ideal for daytime use or when the light is not required.

Parts Desk Insights

Best use case: This is the right light for boats with a T-top, hardtop, or arch where you want a single fixture that serves as both a navigation light and a courtesy light. The thumbscrew adjustment makes switching between modes quick without tools. It’s particularly popular on centre consoles and offshore boats where deck space is limited and multi-function gear is preferred. If you need a fixed all-round pole light without the tri-position feature, see the Perko all-round pole lights below.

• USCG certified for power-driven vessels under 20m — confirm your vessel length before purchasing if you’re close to the limit.
• Mounting adapters for flat, curved, and V-type surfaces are included — fits most standard arch and tower tube profiles.
• The through-base wiring notch keeps your install clean without exposed wire runs.
• Thumbscrew adjustment requires no tools — position can be changed quickly underway.
