Plumb Signs partnered with TRA Medical Imaging on a three-sign brand program for their Gig Harbor location at 4700 Point Fosdick Dr NW, Suite G. The signs follow the visitor in: a wordmark cabinet on the building exterior, a halo-lit diamond identifying the suite on the building's lobby wall, and a second halo-lit diamond anchoring the reception wall behind the front desk.
The exterior cabinet — "TRA MEDICAL IMAGING" set in a clean horizontal lockup — sits on the curtainwall-and-tile facade and gives patients the visual cue from the parking lot. Inside, the two halo-lit diamonds carry the brand the rest of the way: a quiet, premium effect with the aluminum silhouette floating off the wall and a soft white-LED halo wrapping the edges. The reception piece measures 4' wide × 3'10" tall on a 1½" wall stand-off.
Healthcare and medical-imaging environments earn first-impression work that signals confidence. Patients arriving for diagnostic imaging want to know they're in the right place and that the operation behind the door takes details seriously. Three coordinated signs handle that arrival sequence — one outside, one in the lobby, one at reception — all designed, fabricated, and installed in the same project. Built in our Tacoma shop, twelve miles east across the Tacoma Narrows Bridge from the install site.

Four Views · One Arrival Sequence
Patients meet the brand four times on the way to their appointment: at the building from the parking lot, walking up to the suite door, identifying the office from the lobby, and again at the reception desk inside. Each sign was designed, fabricated, and installed by Plumb Signs as one coordinated program — and the approach view shows how the halo reads at lobby distance, not just up close.
Fabrication & Illumination Specs
Halo-lit (reverse-lit) construction: an opaque aluminum face floats off the wall so the LED light source is hidden behind the sign and projects a soft halo of light onto the wall around the silhouette. Sharp by day, glowing by night.
- Sign body: CNC-cut fabricated aluminum diamond, returns welded and finished
- Dimensions: 4'-0" wide × 3'-10" tall
- Construction: Reverse-lit (halo) with concealed LED module bank on the rear
- Stand-off: 1½" wall stand-off for clean LED halo dispersion
- Listing: UL-listed sign assembly
- Illumination: Energy-efficient white LED modules, even spread across the back face
- Power: Low-voltage, low-heat — long service life, low operating cost
- Finish: Automotive-grade paint, matte/satin on the face for glare control
- Mounting: Stud-mount to wall structure with concealed hardware — no through-face fasteners
- Service access: Rear-access LED bank for driver/module replacement without removing the sign face
Built to Plumb Signs' standard for interior reception and brand-ID signs: clean welds, knife-edge returns, paint-grade finish on the face, and a service-friendly LED layout so a single failed module never means pulling the sign down.
How the Project Came Together
1. Brand alignment. The TRA diamond is the brand's identifying mark — paired arrows wrapping a central "TRA" set inside a diamond outline. Reproducing it as a halo-lit interior sign meant getting the silhouette right at scale, including the arrow geometry and the internal counter shapes, so the lit halo reads cleanly without filling in.
2. Shop drawings & CAD. Plumb's in-house design team produced fabrication drawings — dimensioned face profile, return depth, LED layout, mounting-stud pattern, and wall-anchor schedule — sized to the reception wall and the stand-off needed for an even halo.
3. Fabrication in Tacoma. CNC cut, welded, finished, and LED-engineered in our 909 S 28th St shop. Every sub-assembly — face, returns, LED panel — staged together before crating for the run across the Narrows.
4. Install at Gig Harbor. Licensed installer ran the site survey, set the stud pattern off the centerline, anchored to the wall structure with concealed hardware, dressed the low-voltage feed, and commissioned the LED bank. From scaffold-up to lights-on, the sign was set and commissioned in a single visit.
Why a Halo-Lit Logo for the Reception Wall
Halo lighting — also called reverse-channel or backlit — sits between the loudness of a face-lit channel letter and the quiet of a flat dimensional logo. Light comes from behind the sign, the silhouette stays sharp and opaque, and a soft glow rings the edges. The result reads premium in any lighting condition: confident at midday, atmospheric in low light, never harsh.
For reception walls, lobby ID, and donor-recognition installs, halo-lit construction holds up across a few useful axes: the face is paintable and brand-accurate; the LED hardware lives behind the wall plane so nothing competes with the logo geometry; the lit effect photographs well; and the energy load is low enough to run on through business hours without a noticeable utility line item. It is the construction Plumb Signs reaches for first when a client wants their brand to arrive in the room without shouting.
Interior Sign Services in Gig Harbor & the Kitsap Peninsula
Plumb Signs is based in Tacoma — twelve miles east across the Tacoma Narrows Bridge from this office. That short hop means site survey, install, and any future service call happen without travel-day overhead. The same crew that builds the sign drives it over the bridge to set it.
We design, fabricate, and install commercial signage — exterior monuments, channel letters, illuminated cabinets, wayfinding, ADA-tactile, interior reception and lobby ID, halo-lit logos, and dimensional letter walls — across Gig Harbor and the wider Kitsap Peninsula: Gig Harbor, Bremerton, Port Orchard, Silverdale, Poulsbo, Bainbridge Island, Kingston, and Belfair.
