Partswcgg 4" Double-Face LED Trailer Lights — 2-Pack 48-LED 10–30V, Pivot Post Mount

Partswcgg 4" double-face LED trailer lights are a pair of 48-LED, post-mount signal lamps that deliver front amber and rear red illumination with multi-angle mounting for trucks and trailers.

These two 4-inch pedestal lights combine bright amber and red LEDs into a compact dual-face assembly engineered for stop, turn, tail and parking functions. Built to accept 10–30V systems, each unit houses 48 LEDs (24 amber, 24 red) inside a chrome-plastic bezel and offers a pivoting mounting post so you can orient the lamp for forward, rearward or side signaling. The simple three-wire hookup and universal fit make these lights practical additions for commercial trucks, trailers, farm equipment and other heavy-duty vehicles.

How do these lights provide both front and rear signaling?

Each lamp has two distinct lenses — an amber lens facing forward and a red lens facing backward — so one housing performs multiple functions. The LEDs are wired to allow high- and low-brightness modes, giving you visible signals whether used as turn, brake, tail, or parking lights.

• Front-facing amber lens for turn and directional signaling
• Rear-facing red lens for brake and tail illumination
• 3-wire system: black = ground, red = high brightness, white = low brightness
• 48 total LEDs: 24 amber + 24 red for strong visibility

Will these lights fit my vehicle and electrical system?

The lights are designed as universal pedestal-mounted units compatible with most 10–30V vehicle electrical systems. Their post-mount base and multi-angle pivot let you position the lamp for fender, bumper or side mounting, making them suitable for trailers, trucks, and agricultural machines.

• Wide operating voltage range: 10V–30V
• Post mount with multi-directional pivot (90° or 180° orientation)
• Compact 4" diameter for tight mounting spaces
• Works with heavy trucks, trailers, farm equipment and more

How do I wire and control high/low brightness modes?

Wiring follows a straightforward three-conductor layout: ground, high-brightness feed, and low-brightness feed. Use the red lead for the brighter mode (both faces illuminate brighter) and the white lead for low/marker illumination; black attaches to chassis ground.

• Black lead: chassis ground
• Red lead: high-brightness output (both faces activate)
• White lead: low-brightness/marker output (both faces activate)
• Leads exit through the mounting post for protected wiring

What durability and support can I expect?

The lamp shell uses chrome-finish plastic and an LED array that minimizes maintenance compared with incandescent bulbs. Partswcgg backs the lights with a one-year warranty and commit to customer support with a 24-hour response window for pre- and post-sale inquiries.

• Chrome plastic housing for corrosion-resistant appearance
• LEDs reduce bulb replacements and power draw
• 1-year limited warranty from date of order
• Customer service response within 24 hours

Who is this for? These dual-face 4" LED pedestal lights suit vehicle owners and fleet managers who need versatile, compact signaling on trailers, heavy trucks, agricultural implements and utility equipment. If you want an easy-to-wire, multi-function lamp with adjustable mounting angles and wide voltage compatibility, this Partswcgg two-piece set is designed to meet those needs without complex installation or frequent maintenance.
