Hella marine NaviLED TRIO 2LT980650-001 connections

2LT980650-001 combines masthead tricolour navigation sectors with an all-round white anchor light. The instructions describe the tricolour for sailing vessels under 20 m, and exclude its use while motoring or motorsailing. Select the vessel's appropriate navigation-light arrangement for the activity; an electrically illuminated lamp alone does not establish that the displayed lights are correct.

Black is common negative, red supplies tricolour navigation and blue supplies the white anchor function. Provide independent mode switching and a fuse no larger than 3 A as directed by Hella. Keep the functions distinct instead of joining both positive leads into one always-on feed. The catalog preserves all three physical leads but does not implement a navigation/anchor selector or interlock.

The current instruction sheet specifies 9–33 V input. It gives less than 3.5 W for combined port/starboard/stern and less than 1.5 W for anchor; its wiring table rounds these to less than 4 W and less than 2 W. The catalog uses the tighter technical-specification navigation bound, equivalent to approximately 0.29 A at nominal 12 V. Change the operating budget for anchor use and actual duration. Do not add the two modes as if both were required continuously. Terminal limits use the 3 A protection ceiling as a planning bound, not connector ampacity.

Install the lamp where the navigation sectors and anchor light remain unobstructed. Align the mounting base to the vessel's fore-and-aft direction using the arrow and the installation drawing; the cable exit alone is not a reliable substitute for checking sector orientation. The sealed light engine fits over its mounting shaft and must be seated and secured as instructed.

Route the mast cable with strain relief and seal the connection without stressing the short factory cable. A large mast height makes the complete supply-and-return run important even for this small load. Confirm the voltage at the lamp, not just at the distribution panel.

At dusk or in suitable controlled conditions, check port red, starboard green and stern white from their intended viewing sectors. Then switch to anchor and confirm the all-round white function. Verify that the panel's labels match what lights up at the masthead, and that selecting one operating mode does not leave the other unintentionally energized.

If one function fails, measure that positive feed against the shared negative and inspect the switch and cable joints. If both fail, start with the shared return and supply protection. The light engine is sealed; opening it to repair an LED compromises the intended assembly.

Hella NaviLED TRIO installation instructions, PDF pp. 1–2, covers operating modes, alignment, power and the color-coded leads. Official product page identifies the part. Check the label on older hardware, since earlier supply ranges differ from the reviewed sheet.
