3/4 in Side Marker Lights 20 Pack - Amber & Red with Harness

In this review the 20 Pcs 3/4 Inch Side Marker set is presented as a practical lighting kit for owners of trailers, trucks and pickups who need a straightforward way to add or replace multiple marker lights. The kit stands out because installation is truly simple: each light uses a plug-in design with a 2 prong harness roll so a full run of markers can be installed in minutes without complex wiring, making it especially useful for DIYers and fleet maintenance teams who value speed and reliability.

Key Features

• Plug-and-play installation: The included 2 prong harness roll and female plugs let users install the markers quickly without splicing or advanced wiring.
• Balanced kit mix: The package contains 10 amber and 10 red 3/4 in markers so users get a complete set for typical side and clearance layouts.
• Bright SMD LEDs: Each marker uses 3 high quality 2835 SMD LEDs for stable, visible light output useful in daytime and nighttime conditions.
• Rugged construction: Silicone rubber housing and a PC lens make the markers waterproof, shockproof and vibration resistant for heavy duty use.
• Pre-spaced connectors: The harness features 6.5 in (17 cm) spacing between plugs which simplifies alignment and mounting along a trailer or truck side.

Who It's For

The kit is best for pickup and trailer owners, small fleet operators, and DIY mechanics who need multiple side marker lights and want to avoid time-consuming wiring. It is also a good choice for those replacing cracked or dim factory markers and who prefer a full set with matching amber and red lenses.

Those who should look elsewhere include buyers who need sealed single replacement lamps with a different mounting size or users requiring custom wiring harnesses with specialized connectors beyond the included 2 prong roll. Also, if a vehicle requires integrated marker electronics, a simple plug-in kit may not meet that need.

Pros & Cons

Cons

• Harness spacing is fixed at 6.5 in which may need adjustment for nonstandard layouts.
• The kit uses a basic 2 prong connector which may not match proprietary vehicle sockets without an adapter.

Specifications
