Why 10‑8

Equipment failure isn't an option.

When equipment fails in the field, it's almost always the part you can't see — crimps that corrode, wiring that chafes through, connections that quit when the heat and vibration set in. We build against every one of them, matched to the mission: front-line trucks get sealed, weatherproof harnesses built to take the heat, and every vehicle gets clean, supported, labeled runs and systems tested before they leave the bay.

Robust by design

Sealed Deutsch connectors, marine-grade wire, heat-shrink and loom where the mission demands it. Built to survive heat, vibration, water and years of hard service.

Tested before it ships

No truck leaves the shop until every light, siren, switch and circuit has been verified end-to-end. It works on day one — and on the worst night of the year.

Built for our departments

From the smallest stations to the largest agencies, we build for the departments across our region and beyond. Straight talk, fair pricing, and trucks ready to answer the call.

Capabilities

One shop. The whole build.

From a single light bar to a complete ground-up fire or police build, 10‑8 handles it turnkey — so you bring us your truck and get back one that's ready to run.

Emergency Lighting

Light bars, hideaways, surface and grille lights — Whelen-preferred, wired for full programmability.

Sirens & Speakers

Siren amplifiers, control heads and speakers mounted and tuned for cut-through on the road.

Control Consoles & Switching

Custom-fabricated aluminum consoles and clean switch layouts built around the way your crews actually work.

Custom Wiring & Harnesses

Sealed, labeled, serviceable harnessing that's the backbone of a truck that never quits.

The Difference Is In The Details

The best wiring is the kind you never think about.

The build that lasts is the one you never see — the harness behind the dash, the connector under the body, the run that's loomed, sealed and strain-relieved so it shrugs off a decade of mud, heat and washdowns.
