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

In this review the MADCATZ 50 Pcs 3/4' amber LED marker lights are presented as a practical, no-fuss lighting solution for 12V vehicles. The single biggest reason to buy is the plug-and-play design: the lights come with a continuous two-prong harness roll and 50 female bullet plugs, so installation is straightforward for anyone replacing multiple side marker lights. For fleet owners, DIY trailer owners, and pickup or RV users looking for bright, consistent amber markers, this kit bundles quantity, wiring, and connectors into one ready-to-install package.

Key Features

• Easy Installation: A continuous 2-prong wire harness with double female bullet plugs means the set is ready to plug in without complex splicing or rewiring.
• Super Brightness: Each 3/4' marker contains three 2835 LEDs to provide clear amber illumination that is visible for side marker and clearance applications.
• Long Life LEDs: The LEDs are rated for long service life and low power consumption, making them suitable for vehicles that need reliable marker lights over time.
• Consistent Spacing: The harness roll uses about 6.5 in spacing between plugs, which matches standard side marker layouts and simplifies positioning along trailers or truck beds.
• Complete Kit: The package includes 50 marker lights and a harness roll with 50 female plugs so you get bulbs and mating connectors in one purchase.

Who It's For

This kit suits owners of trailers, trucks, pickups, RVs, and commercial fleets who need to replace or add multiple side marker lights quickly. The continuous harness and large quantity make it especially useful for refurbishing older trailers or fitting long vehicles where many markers are required.

It is less appropriate for someone who needs a single replacement lamp or who requires custom wiring lengths shorter than the harness provides; hobbyists who prefer hardwired custom circuits may want individual lamp assemblies rather than a continuous plug roll.

Pros & Cons

Pros

• Includes 50 marker lamps and a roughly 25 ft continuous harness, so you can outfit an entire trailer in one go.
