Partsam 20-Pack 3/4" Smoked-Lens Red LED Marker Lights — 12V Waterproof, Low-Profile Clearance/Side/Tail Indicators

Partsam 20x 3/4" smoked-lens red LED marker lights are compact, waterproof 12V indicators designed for clearance, side-marker, and tail light use on trailers, trucks, RVs and more.

These mini round LEDs come as a pack of 20 and drop into a 3/4" diameter hole, offering a low-profile and energy-efficient replacement for incandescent markers. Built for exterior vehicle use, each lamp is sealed against moisture and vibration, includes two wiring leads for straightforward installation, and delivers consistent red illumination through a smoked lens for a subtle, modern look.

How do these lights install and wire on my vehicle?

Installation is simple: drill a 3/4" hole, insert the lamp, and connect the two leads—white is negative, black is positive. The compact housing sits flush when mounted and the included ground lead makes attachment to metal surfaces easy.

• Fits into a 3/4" diameter hole with a snug, low-profile fit
• 2-wire hookup: white = negative, black = positive
• Includes wiring leads and grounding option for secure mounting
• Suitable for drilling into fenders, body panels or custom mounts

Will these markers hold up to road and weather conditions?

Yes—each lamp is sealed to resist water and dust, and the LED elements are inherently more vibration-resistant than incandescent bulbs. That makes them suitable for exposed locations on trailers, RVs, and other utility vehicles where splash and road debris are common.

• Sealed waterproof design for exterior exposure
• Durable LED chips reduce failure from vibration
• Smoked lens shields light while maintaining visibility
• Corrosion-resistant housing for long-term use

What applications and vehicle types are these lights compatible with?

These 3/4" LED markers are versatile: use them as side marker lights, clearance lights, tail or identification lights on a wide range of 12V vehicles. Their small size and neutral smoked styling make them a good fit for commercial and recreational vehicles alike.

• Trailers, semi-trailers, and cargo vans
• Pickup trucks, buses, RVs, campers and caravans
• ATV/UTV and utility equipment for auxiliary lighting
• Replacement for incandescent marker lights and custom installs

How do these lights perform compared with incandescent markers?

LEDs consume far less power while providing steady light output and longer lifespan than incandescent bulbs. This pack of 20 offers an efficient upgrade that reduces maintenance and draws minimal current from a 12V system.

• Lower power draw for reduced battery impact
• Longer operating life—fewer replacements needed
• Instant-on illumination with no filament to burn out
• Consistent brightness under vibration and temperature changes

If you want a durable, low-profile set of clearance and side markers that are quick to fit into standard 3/4" holes and reduce maintenance compared with incandescent bulbs, this 20-piece kit is a practical choice.
