<h3>Chris Products: Trusted Motorcycle Lighting &amp; Visibility Parts</h3><p><strong>Chris Products</strong> has been a cornerstone of the motorcycle and ATV aftermarket parts industry for over three decades. Based in Hillsboro, Oregon, the company has built its reputation by delivering high-quality, USA-made components that meet or exceed DOT standards — giving riders confidence that every part is built for safety and real-world performance. Records show the business was established in 1982, and that long track record speaks for itself among serious riders and builders alike.</p><h3>Lighting &amp; Visibility at the Core</h3><p>Lighting and visibility accessories are at the heart of the Chris Products lineup. The brand is perhaps best known in the Harley-Davidson aftermarket as a premier supplier of turn signal light lenses — offering replacement lenses in amber, red, clear, smoke, and blue finishes to cover decades of FX, FXR, Softail, Dyna, Sportster, and touring models.</p><p>Whether you need a complete new assembly or just a fresh lens, Chris Products has you covered. Their <a href="/5780-chris-products-turn-signal-light-2872">turn signal lights</a> and <a href="/11729-turn-signal-light-assembly-chris-products-5780">turn signal light assemblies</a> are engineered for clean, hassle-free installation, and their <a href="/5780-chris-products-turn-signal-light-lens-11728">turn signal light lenses</a> make it easy to restore proper function and fresh style without replacing an entire unit. Both incandescent and LED turn signal options are available, with DOT-compliant designs that keep riders street-legal without sacrificing style.</p><h3>License Plate Solutions Built for Riders</h3><p>Beyond lighting, Chris Products is widely respected for its <a href="/14259-license-plate-chris-products-5780">license plate</a> accessories and hardware. The brand rounds out a rider&apos;s visibility setup with reflectors engineered to enhance conspicuity from the rear — compact, durable pieces that attach cleanly to license plate areas or rear fenders, adding an extra layer of passive safety on night rides. Their <a href="/5780-chris-products-license-plate-frame-10002">license plate frames</a> bring both form and function, finishing off the rear end of a build with purposeful styling. One of the brand&apos;s standout product segments is their license plate frames, which combine functional protection with classic motorcycle styling — a favorite finishing touch for riders who pay attention to every detail from front to rear.</p><h3>Built for Harley-Davidson, Compatible With More</h3><p>Chris Products has long been a go-to resource for Harley-Davidson enthusiasts, though their catalog extends to a variety of other motorcycle and ATV models. Whether you&apos;re restoring a vintage FX-series Harley or refreshing the look and function of a modern touring bike, Chris Products offers components designed to integrate seamlessly with OEM specifications.</p><p>Their extensive lineup includes OEM-style turn signal assemblies, marker lights, signal brackets, horns, license plate frames, reflectors and essential hardware for Harley-Davidson, metric cruisers and custom builds. Many Chris Products items come as complete kits with detailed instructions, hardware, and components, making them suitable for DIY installation. For riders who demand precision fitment and dependable quality, Chris Products remains one of the most trusted names on the market.</p>
