Triple R Composites Ford Fiesta MK7.5 ST180 Diffuser Fins & Rain Light
Give your Ford Fiesta MK7.5 ST180 a sharper, more purposeful rear end with this diffuser fin and rain light kit. It adds a clean, factory-style finish while making your rear bumper stand out.
Why choose this kit
- Gives the rear bumper a sportier, more aggressive look
- Matches the style of OEM bumper trims with a subtle black finish
- Integrated LED rain light for a motorsport-inspired touch
- Precision fit thanks to CAD design and 3D printed manufacture
- Supplied with stainless steel fitting kit for a tidy install
The kit includes four diffuser fins and a centre mount with LED rain light. The fins help visually break up the rear bumper and give a track-inspired appearance without being over the top.
Each part is CAD designed using scan data taken from the Fiesta MK7.5 ST180 rear bumper. They are produced in tough Nylon 12 on an SLS 3D printer, then media blasted and finished in black for an OEM-style textured look.
LED rain light wiring
The LED centre rain light can be wired to suit your setup. In simple terms:
Red wire – positive feed (power in)
Black wire – earth (ground)
Yellow wire – connect to the positive feed to change the strobe pattern
This lets you choose how the light behaves, for example as a static extra brake light or with a flashing pattern for show or track use where allowed.
Always check local road laws before using any flashing light on public roads.
