Anderson Manufacturing Clearance & Marker Lights - Incandescent
Anderson Manufacturing Incandescent Clearance & Marker Lights
When it comes to keeping trailers, boats, and commercial vehicles visible and road-legal, few names carry the weight of Anderson Manufacturing. As the Anderson Marine Division — a storied arm of Peterson Manufacturing — Anderson has been engineering safety lighting solutions since 1945, building a reputation for reliability, durability, and compliance that professionals and enthusiasts have trusted for decades. Their incandescent clearance and marker lights represent the backbone of that legacy: proven, practical, and built to perform under real-world conditions.
Purpose-Built for Visibility and Safety
Clearance and marker lights serve a critical role on any towed or wide vehicle — they define the outermost edges of a trailer or vessel at night and in low-visibility conditions, giving other drivers the spatial reference they need to pass safely. Anderson Manufacturing’s incandescent offerings in this category are engineered specifically for surface-mount applications on boat trailers, recreational trailers, and commercial haulers where straightforward, dependable lighting is the priority.
Key Product Lines and Features
Anderson’s incandescent marker and clearance light lineup includes well-regarded series such as the E150 / E150KA — a PC-rated rectangular design measuring approximately 2.48” x 1.20” — which functions as both a side marker and a clearance light, and can serve as a combination unit when properly mounted. These lights are PC-rated for polycarbonate construction, offering impact resistance that stands up to road debris and trailer vibration. The E151A is a compact P2-rated rectangle (approximately 2.12” x 1.12”) that brings the same versatile dual-function capability in a slightly smaller footprint. For oval applications, the M116A features a wedge-profile, surface-mount design that is especially popular for use on recreational trailers, with a single electrical lead that grounds through the mounting hardware — keeping installation clean and simple.
- PC-Rated and P2-Rated Lenses: Polycarbonate construction resists cracking and yellowing over time, maintaining light output and appearance through seasons of use.
- Long-Life Incandescent Bulbs: Certain Anderson incandescent models feature 15,000-hour-rated bulbs, maximizing the service interval between replacements.
- Sealed, Sonic-Welded Construction: Many Anderson marker and clearance housings have their lens and body sonic-welded into a single sealed unit, significantly reducing the risk of moisture intrusion — a critical advantage in marine and wet-road environments.
- Surface-Mount Simplicity: The wedge and rectangle profiles are designed for straightforward surface installation, with single-lead wiring that simplifies electrical connection on trailers of all types.
- Dual-Function Capability: Multiple Anderson incandescent models are approved for use as either a side marker light or a clearance light, or as a combination of both, offering flexibility during installation.
Why Choose Incandescent for Your Trailer or Marine Application?
While LED lighting has grown in popularity, incandescent clearance and marker lights remain a go-to choice for replacement and restoration applications — particularly on older trailers where incandescent sockets are already in place. Anderson’s incandescent units are direct-fit solutions that eliminate the need for adapter harnesses or socket modifications, making them a practical, cost-effective choice for maintenance and repair. Their amber lenses meet standard DOT/FMVSS visibility requirements for marker and clearance applications on vehicles and trailers.
Whether you’re replacing a failed light on a boat trailer, maintaining a fleet of recreational haulers, or sourcing parts for a restoration project, Anderson Manufacturing’s incandescent clearance and marker lights deliver the dependable performance this brand has been known for across generations of trailer owners.
