Motone Custom Billet Turn Signals - Brushed Aluminum Complete Set (4 Indicators)

Description

For riders building a complete custom motorcycle or refreshing all four corners with cohesive lighting, this Motone set delivers four precision-machined indicators in hand-brushed aluminum finish. Unlike piecing together mismatched pairs, this complete kit ensures uniform appearance across front and rear positions while providing E-marked certification for legal compliance—all at a value price point compared to purchasing individual pairs separately.

Key Features

CNC-Machined 6061 Billet Aluminum Construction

All four indicator bodies are turned from solid 6061-T6 aluminum billets using computer-controlled precision machining, ensuring identical dimensional tolerances across the set. Unlike cast indicators that exhibit batch-to-batch variation in wall thickness and surface quality, CNC billet construction guarantees each unit weighs within 2g of specification and features perfectly concentric lens housing geometry. The aluminum construction reduces weight by 78% compared to OEM plastic housings (42g vs. 185g per unit).

Hand-Brushed Aluminum Finish with Natural Patina Development

Each indicator receives a directional hand-brushed finish using 220-grit abrasive media, creating fine linear grain patterns that catch light subtly while hiding minor scratches from handlebar contact. Unlike anodization or powder coating, the brushed natural aluminum finish develops a protective oxide patina over time, providing corrosion resistance without color fading. The raw aluminum aesthetic complements polished engine cases and chrome components on classic British builds.

Universal Dual Lens System with E-Mark Certification

Every indicator includes both clear and amber 40mm diameter polycarbonate lenses, allowing customization based on regional regulations and aesthetic preference. All lenses carry E-mark certification (ECE R6 compliance), ensuring legal street use in European markets and territories requiring certified lighting. The polycarbonate material resists impact from road debris and UV yellowing better than acrylic alternatives, maintaining optical clarity through years of sun exposure.

Premium Osram 10W Amber Bulb Package (Set of 4)

Includes four genuine Osram 12V/10W amber bulbs engineered specifically for high-vibration motorcycle applications. Osram’s dual-contact bayonet base design ensures positive electrical connection under sustained engine vibration, while the amber glass envelope provides inherent color filtration (2200K) for enhanced daytime visibility. The 10W power output meets SAE and ECE brightness requirements for both running lights and turn signal flashing across most jurisdictions.

Stainless Steel Mounting Stems with Complete Hardware Kit

Each unit features a precision-turned 10mm diameter stainless steel 303 mounting stem with 30mm of usable threaded length, accommodating mounting brackets from 2mm to 25mm thickness. The stainless construction prevents thread galling and corrosion at mounting interfaces—critical for long-term durability where aluminum stems corrode or seize. Standard M10x1.0 threading provides universal compatibility with aftermarket brackets and OEM mounting points across Japanese and European motorcycles.

Installation Note: These indicators use universal bullet-type electrical connectors and require adapters for direct plug-in compatibility with most motorcycle OEM wiring harnesses. Torque mounting stems to 8-10 Nm maximum to prevent thread damage. For brushed aluminum maintenance, avoid abrasive cleaners—use pH-neutral soap and water only. The natural aluminum finish will develop a protective oxide layer (light gray patina) over time, which can be removed with fine Scotch-Brite if desired, though this patina actually enhances corrosion resistance. Test flash rate after installation—low wattage bulbs may require load resistors or electronic flasher relay replacement to prevent hyper-flashing.
