Partsam 6.3-inch Oval LED Stop Tail Turn Marker Lights Red 2-Pack — 24 LED Sealed Waterproof Flush-Mount

These are Partsam 6.3-inch sealed oval LED marker lights that combine stop, tail and turn functions in a single waterproof flush-mount unit for 12V truck, trailer and marine use.

Built to replace conventional incandescent lamps, these Partsam sealed marker lights use 24 high-efficiency LEDs behind a clear lens with a red output. The PC lens and housing are welded to create a permanent weatherproof seal, while the LED circuit board receives a conformal coating to resist moisture and environmental exposure. Each lamp is hardwired with three leads so one fixture provides low-brightness running/tail lighting and high-brightness stop/turn/brake output.

How do these lights handle wet and harsh conditions?

The lens and housing are welded together for a permanent waterproof barrier, and the LED board has conformal coating to protect electronics from moisture and contaminants. That construction reduces the risk of fogging and shorting compared with non-sealed fixtures.

• PC lens and housing welded for a continuous waterproof seal
• Conformal-coated LED circuit board for environmental protection
• Rubber grommet included to seal the installed hole and damp vibrations

What wiring and light functions are included, and how do I connect them?

Each lamp is hardwired with three leads: one for ground, one for high-brightness stop/turn/brake, and one for low-brightness tail/running lights. Note that there are two variants in the market where the ground wire color may be black or white; functionality remains the same.

• Red wire — high-brightness stop/turn/brake circuit
• White wire — low-brightness tail/running circuit (or black on some units for ground)
• Black or white wire — chassis ground depending on the unit; verify before final hookup

Will these fit my vehicle and how big is the cutout?

The lamp's visible body measures 6.3" x 2.14" x 1", and the full size including the rubber grommet is approximately 7.28" x 3.2" x 1.1". Plan for a roughly 6.4" hole to install the fixture flush in most panels.

• Visible lamp dimensions: 6.3" x 2.14" x 1"
• With grommet: 7.28" x 3.2" x 1.1" — installs flush into a ~6.4" cutout
• Universal fit for trucks, trailers, RVs, boats and heavy-duty equipment

How bright and long-lasting are the LEDs?

Each unit contains 24 LEDs engineered for high efficiency and long life compared with incandescent bulbs. The two-level output gives bright, attention-getting brake or turn signals while maintaining lower-power running lights for visibility without glare.

• 24 LEDs provide a distinct, even illumination pattern
• High-brightness red for brake/turn; low-brightness red for tail/running
• LEDs reduce power draw and require less frequent replacement

Who this is for: Drivers and fleet technicians who need durable, low-maintenance marker lights for trucks, trailers, RVs, boats and specialty vehicles. These Partsam sealed oval LEDs suit owners upgrading from incandescent lamps, anyone needing a watertight flush-mount installation, and professionals seeking a universal 12V lamp with combined stop/tail/turn capability.
