Partsam 6" Amber LED Marker and Turn Signal Lights, 2-Pack, 21-LED Sealed 12V

These two 6" x 2" amber LED fixtures combine a low-brightness running light and a high-brightness turn signal in a single, surface-mount housing. Each lamp holds 21 LEDs, is wired with three leads (ground, low, high) and is designed for simple hardwired installation on any 12V vehicle. The sealed enclosure protects internal components from road spray and normal weather exposure while delivering a compact, multi-function lighting solution.

How do these lights switch between marker and turn signal modes?

The Partsam units use a 3-wire setup: a ground wire, a low-intensity wire for marker or running mode, and a high-intensity wire for turn signal or brake output. When the vehicle sends a low-voltage feed the light runs dim; when the high-intensity feed is applied the same LEDs illuminate brighter to act as a turn or brake signal.

• Black wire: ground connection for stable circuit return.
• White wire: low brightness for marker/clearance or running light use.
• Red wire: high brightness for turn signal/brake-style output.
• Can be used as only marker or only turn signal by leaving one wire unused.

What are the dimensions and electrical characteristics I should know?

Each light measures about 6" long, 2" high and 1.4" deep with a hole-to-hole mount spacing of roughly 4.8", making it compatible with many standard trailer and vehicle mounting patterns. They operate at 12V DC and offer separate current draws for dim and bright modes.

• Overall size: approximately 6" x 2" x 1.4"; hole spacing ~4.8".
• LED count: 21 amber diodes per lamp for visible output.
• Power draw: about 20 mA in dim/marker mode, ~110 mA in bright/turn mode.
• Designed for 12V systems commonly found on trailers, RVs, trucks and golf carts.

How durable are these lights and where can I mount them?

The housing is sealed to resist water and road debris under normal conditions, so they suit exposed exterior mounting on trailers, campers and utility vehicles. They are surface-mount fixtures intended for permanent hardwired installation; avoid submerging them or exposing them to heavy continuous immersion.

• Sealed amber lens and housing for splash resistance and road durability.
• Surface-mount installation with standard screw holes for secure mounting.
• Suitable for trucks, trailers, RVs, campers, motorhomes and golf carts.
• Not rated for full underwater use—avoid installation where full immersion is likely.

Who is this for: These Partsam 6" amber rectangular lights are ideal for vehicle owners who want a compact, multi-function lighting solution—particularly trailer builders, RV and camper owners, pickup and truck drivers, and fleet maintainers who need both marker and turn signal capability from a single, hardwired lamp. They suit DIY installers who prefer simple 3-wire hookups and anyone replacing worn or single-function marker lights with a brighter, dual-mode LED option.
