MADCATZ 50 Pcs 3/4ft LED Amber Marker Lights with 2-Prong Harness

In this review the MADCATZ 50 Pcs 3/4' LED clear lens amber marker lights package is evaluated for installers and fleet owners who need a bulk, ready-to-wire solution. The bottom line: this kit is useful when replacing many side marker lights at once because it pairs fifty super-bright 3-LED amber lamps with a continuous 2-prong wire harness roll and fifty female bullet plugs to simplify wiring and reduce installation time. It is best for 12V trailers, trucks and campers where uniform, long-lived marker lighting is required.

Key Features

• Bulk kit: Fifty clear lens amber marker lights and a harness roll are included, so a whole trailer or multiple vehicles can be refitted from one package.
• Super brightness: Each 3/4' lamp uses three 2835 LEDs to deliver extra visibility while remaining energy efficient and running cool.
• Long life: The LEDs are specified for extended use with an estimated 50,000 hour lifetime, reducing replacement frequency.
• Plug-ready harness: The roll contains about 25 ft of double female bullet plug harness with 6.5 in spacing to match typical side marker placements.
• Quality wiring: The harness uses 18 AWG tinned copper and a PVC jacket with 0.18 in bullet contacts for corrosion resistance and reliable electrical connection.
• Wide compatibility: Designed for universal 12V vehicles including trailers, pickups, RVs and boats, making it a flexible fleet option.

Who It's For

The kit is best for professional installers, fleet maintenance crews, and DIY owners who need to replace or install multiple side marker lights at once; the included continuous harness and 50 female plugs make it faster to wire a full trailer or several vehicles. The product suits anyone who prefers a plug-and-play approach over individual pigtails for each lamp.

It is not ideal for someone who only needs a single replacement lamp or who requires a custom-length harness with different plug spacing, since the harness has fixed 6.5 in spacing and comes as a roll intended for multiple lights.

Pros & Cons

Pros

• Durable wiring: 18 AWG tinned copper and PVC jacket offer solid conductivity and basic protection against the elements.

Cons

• Fixed 6.5 in spacing on the harness may require trimming or re-routing for nonstandard marker layouts.
