Plug & Play Pan Tail Light – Triumph Motorcycles (2001–2016, 2016+)
If you ride a modern classic Triumph, you know the stock tail light is the first thing begging for an upgrade. The factory plastic just doesn’t cut it—visually or physically—on a bike built with real metal and heritage in its bones. That’s why we engineered the Plug & Play Pan Tail Light: a billet aluminum and stainless steel assembly that bolts straight to your Triumph’s factory mounts, no drilling or wire hacking required.
Inspired by the flat, purposeful lines of classic British roadsters, this pan-style tail light is all about clean integration and functional design. The body is crafted from proper metal, not plastic, so it feels as solid as it looks. The plug-and-play harness with OEM-style connectors means you’re not spending your weekend deciphering wiring diagrams—just bolt it up, plug it in, and ride.
You get two mounting options—license plate or shock mount—so you can dial in the look and function that fits your build. If you’re running custom turn signals, dedicated adapters and harnesses are available to keep everything tidy and reliable. The integrated license plate light keeps things legal and streamlined.
This isn’t just a cosmetic swap. It’s a real upgrade in fit, finish, and rider confidence—built to match the quality and intent of your Triumph. If you want your rear end to look as dialed as the rest of your bike, this is the tail light that belongs on your build.
Fitment Notes
• Plug & Play Tail Light requires you to update the mounting location of your turn signals. We offer two plug & play options: License Plate Mount, Shock Mount.
• For customers looking to use their own turn signals, we offer a selection of DIY turn signal adapters and turn signal harnesses.
• Replace the stock plastic taillight with a taillight crafted from a mix of aluminum and stainless steel components. Bikes are supposed to have metal components.
Key Features & Benefits

- Customizable Turn Signal Mounting: Choose from license plate or shock mount options, or use your own signals with available adapters for a tailored fit.
- Precision Fitment: CNC machining ensures tight tolerances and a clean look that matches the lines of Triumph modern classics.

Performance
With a handcrafted look that takes its inspiration from Moto GP exhausts seen on the track,
British Customs’ GP Slip On Exhaust is a unique choice for your Triumph, providing an updated alternative to the typical classic style exhausts available for Triumphs while delivering real performance benefits.
The GP exhaust is the lightest British Customs stainless steel exhaust system, manufactured from lighter 20 gauge stainless steel (rather than 18 gauge used in our other exhausts) and updated internally with our new race core instead of the heavier, louvered cores used in the Predator Pro and Sleeper Pro Slip On Exhausts. The perforated baffle core is wrapped in stainless steel packing and allows for increased air flow, less weight, and a higher pitch performance exhaust sound.
Each segment of this stainless steel exhaust system is rolled, hand shaped, fitted, and brushed in Gardena CA, manufactured with care by our expert craftsmen who leave the welds exposed to preserve and feature the craftsmanship poured into it. Design features like rubber isolated exhaust hangers reduce engine vibration and bracket fatigue, and each exhaust is finished with a riveted stainless steel end cap making the exhaust serviceable if you send it back to us for repacking.
Key Features
- One of the first & original "GP" designs for Triumph modern classic models
- 100% Stainless Steel Construction
- Light - weighs approximately 2.65 lbs per muffler
- Bolt-on installation using factory mounting points
- Perforated baffle core for higher engine flow, weight savings, and race sound
- Rubber isolated exhaust hanger to reduce bracket fatigue and engine vibration.
- Exposed TIG welds for a handcrafted look
NOTES: The GP Slip On Exhaust will not work with a center stand.
Liquid Cooled Bonneville T100/T120 prices are higher compared to other models due to 2x gaskets that are included for installation.

Handling
Galfer Brake Kit for Triumph Motorcycles
When upgrading your brake rotors, it is recommended that you replace your brake pads as well. Installing a new rotor without installing new a brake pad will reduce the effectiveness of your braking components and cause both the rotor and pad to wear prematurely. To provide an easy solution and extend savings to our customers, British Customs has worked with Galfer USA to create a Triumph-specific rotor/pad combo that will drastically improve the braking performance of your Triumph. This is the rotor/pad combo that we run on our bikes and we recommend this set up for your Triumph build.
Rotor Description: Full floating to ensure optimum brake pad-to-rotor contact. Every high-quality, Galfer-patented Wave® rotor is made from a proprietary mix of virgin high carbon 420 stainless steel, laser cut (never stamped), double disc-parallel ground to assure perfect parallel flatness and heat treated to each specific application. KBA and TUV approved. Seamlessly replaces stock rotor. Full instructions provided along with any technical help needed! Precision made in our Galfer factory in Spain.
Features:
- Designed for both street and track use
- Keeps brake system cooler by allowing air to pass over every point of a brake pad surface
- Best friction surface of any stainless steel rotor
- Full Floating Wave® blades ensure optimum pad-to-rotor contact for maximum stopping force and feel
- Seamlessly replaces stock rotor
- Extremely predictable and consistent
- Provides outstanding performance even in the most aggressive conditions
- Drastically increases lever feel / modulation and brake torque
- Advanced Brake Pad ceramic composites ready to withstand higher temperatures than regular semi-metallic carbon brake pads
- HH friction Pad rated compounds deliver excellent feel and modulation

The Triumph Street Twin is a highly capable bike. For this build we sought to equip the 900cc model for a longer ride so we used our shop Street Twin which has gone through multiple build iterations. Ergonomics and luggage were top priorities, as well as prepping the bike for the varying road conditions of the PNW.
