Perterson Trailer Clearance Marker Lights M154A-R Pair — Submersible Incandescent, Front Amber & Rear Red

Perterson's M154A-R multi-pack provides two submersible incandescent clearance/side marker lights designed for reliable front amber and rear red trailer marking on a wide range of utility, boat, RV, and cargo trailers.

These two M154A-R lamp units are built for straightforward OEM-style replacement and aftermarket upgrades where dependable, visible marker lighting is needed. Each housing includes long-life incandescent bulbs rated for extended service hours and the fixtures share mounting footprint compatibility with the 154 series, making swap-in installation simple when using the correct bracket hardware. The lights are offered as a pair to cover both front and rear requirements for trailers wider than 80 inches and are suitable for marine and land-based towing applications thanks to their submersible design.

How do these lights fit my trailer and mounting options?

The M154A-R uses the standard 154-series mounting pattern, so it installs in the same locations as many OEM marker lights. Note that mounting brackets are sold separately (see Perterson #154-11K) and the fixtures can be mounted either on top or on the side of most fenders. Because they’re compact, they suit tight spaces and curved fender profiles without extensive modification.

• Direct 154-series footprint for easy replacement
• Top or side fender mounting flexibility
• Bracket required separately: Perterson #154-11K
• Compact housing fits curved or narrow fender edges

What kind of light output and durability can I expect?

Each unit contains two long-life incandescent bulbs rated for extended service life, providing consistent visibility for clearance and marker functions. The bulbs are non-replaceable within the sealed housing, which reduces moisture intrusion points and improves waterproofing for marine use. The housings are designed to be submersible and resist corrosion in wet environments, making them suitable for boat trailers and other moisture-exposed applications.

• Two sealed, long-life incandescent bulbs per unit (non-replaceable)
• Submersible housing suitable for marine exposure
• Resistant to moisture and typical road corrosion
• Available colors for front (amber) and rear (red) placement

Which vehicles and uses are these marker lights appropriate for?

The lights were designed for broad trailer use — from small utility trailers to large horse, cargo, and boat trailers — and are also applied to RVs, campers, and commercial fleets. They’re commonly used where a simple, rugged marker or clearance light is required rather than a multifunction LED assembly. Their submersible rating expands usability to marine settings like boat trailers and marina docking equipment.

• Utility, cargo, horse trailers and boat trailers
• RV, camper, and commercial fleet marker applications
• Off-road and agricultural vehicles needing basic marker lighting
• Emergency roadside kits and marina docking lights

Are there any maintenance or compatibility notes I should know?

Because the bulbs are sealed and not serviceable, the whole unit is replaced if the lamps fail; this trade-off improves waterproofing and reduces corrosion risk. Verify whether you need the separate mounting bracket Perterson #154-11K for secure installation. Confirm local regulations for required marker colors and mounting heights before installing on road-going trailers.

• Non-replaceable bulbs—replace the entire unit if failed
• Mounting bracket sold separately (Perterson #154-11K)
• Check local trailer lighting regulations for compliance
• Use in paired front/rear configuration for proper marking

Who is this for: The Perterson M154A-R two-pack is aimed at trailer owners, marine tow operators, fleet managers, and DIY mechanics who want rugged, OEM-compatible clearance and side marker lighting. It suits anyone needing dependable, sealed marker lights for boat trailers, utility and cargo trailers, horse and RV trailers, or basic commercial vehicle marking where simplicity and waterproof performance matter.
