Semi Truck LED Headlights & Headlight Assemblies

Replace factory lighting or upgrade your truck with LED, projector, halogen, and custom headlight assemblies.

LED & Projector Headlights

Options include LED projectors, daytime running lights, sequential turn signals, position lights, halo accents, and chrome or blackout housings for Peterbilt, Kenworth, Freightliner, Volvo, Western Star, and other trucks.

Halogen & Factory-Style Headlights

Shop replacement headlight assemblies for drivers who want factory-style fit and lighting performance, including truck-specific halogen replacements.

Round & Custom Headlights

Choose dual-round, 5x7, 7-inch, stainless, hot-rod, and custom headlight assemblies for traditional and custom semi truck builds.

Semi Truck Marker & Clearance Lights

Marker and clearance lights help define the truck's width, height, and position while adding custom lighting around the cab, sleeper, tanks, and frame.

Round, Mini & Beehive Marker Lights

Shop 3/4-inch mini LEDs, 2-inch round lights, beehive lights, rectangular markers, and other popular sizes and styles. The assortment includes both LED and incandescent replacements.

Marker Light Bezels, Grommets & Mounts

Complete installations with chrome or stainless bezels, rubber grommets, foam gaskets, bases, and mounting brackets.

Cab, Roof, Visor & Sleeper Lights

Add or replace lighting across the upper and side areas of the truck with cab lights, visor lights, sleeper-panel lights, air-cleaner lights, and custom lighting panels. Some kits combine dozens of mini LEDs with panels and wiring harnesses for a complete installation.

Semi Truck Tail, Brake & Reverse Lights

Shop rear lighting for stop, turn, tail, reverse, marker, and auxiliary functions.

Stop, Turn & Tail Lights

Choose round, oval, rectangular, and light-bar styles for rear panels, bumpers, and custom truck builds.

Reverse & Backup Lights

Flood-style and dedicated reverse lights improve visibility behind the truck during backing, hooking, and nighttime work.

Semi Truck Light Bars & Auxiliary LED Lights

Add extra forward, side, or work-area lighting with LED light bars and auxiliary lamps.

Spot, Flood & Combination Light Bars

Spot beams concentrate light farther ahead, flood beams spread light across a wider area, and combination bars provide both patterns. The selection includes large combination bars with side or bottom mounting.

Work & Utility Lights

Use work lights around trailers, equipment, decks, loading areas, and other places where broad illumination matters more than long-distance beam reach.

Warning, Strobe & Emergency Truck Lights

Shop warning bars, strobes, tow lights, traffic directors, and programmable lighting for tow trucks, service trucks, vocational trucks, and other work applications. High-output systems include programmable flash patterns, traffic-director functions, and full-width LED warning bars.

Custom Semi Truck LED Lights

Build a custom lighting setup with colored LEDs, clear or smoked lenses, illuminated panels, sequential signals, accent lighting, and stainless mounting panels. Custom lighting options fit popular areas such as cab panels, sleepers, air cleaners, visors, fenders, bumpers, and rear panels.

Semi Truck Lighting Wiring & Installation Parts

Finish a repair or custom installation with the electrical and mounting parts needed to connect and secure your lights.

Light Plugs, Pigtails & Connectors

Shop 1-wire and 3-wire plugs, Weather Pack connectors, terminals, pigtails, and wiring leads for replacement and custom installations.

Harnesses & Switches

Find headlight harnesses, switch controls, wiring assemblies, and related electrical parts for factory replacement or auxiliary lighting.

Grommets, Bezels, Gaskets & Brackets

Match the lamp with the correct mounting hardware. Options include rubber grommets, foam gaskets, chrome bezels, stainless bezels, brackets, bases, and replacement O-rings.

Replacement Bulbs & Lenses

Keep existing light assemblies working with miniature bulbs, incandescent replacements, colored lenses, screws, sockets, and other service parts.

Find Semi Truck Lights by Truck Make

Narrow truck-specific lighting by Peterbilt, Kenworth, Freightliner, International, Mack, Volvo, Western Star, and other makes before comparing style or lighting technology. For universal lights, confirm the lamp size, mounting style, voltage, connector, wiring, and required installation hardware before ordering. Don’t stop at lighting, check out related categories like: semi truck sun visors, heavy-duty steering wheels, and mud flap hangers with lighting accessories.

Frequently Asked Questions About Semi-Truck LED Lighting

Will LED lights work with my truck's electrical system without modifications?

Most LED lights are designed to work with standard 12V and 24V systems found in semi-trucks. However, some older trucks (pre-2000) may require load resistors or flasher relays to prevent hyper-flashing with LED turn signals and marker lights. Always verify the voltage requirements match your truck's system before purchasing. For trucks with CAN-bus systems (typically 2008 and newer), look for CAN-bus compatible LEDs to avoid dashboard error messages.

How difficult is it to install LED lights, and what tools do I need?

Installation difficulty varies by light type. Marker lights and tail lights typically involve simple plug-and-play connections that take 10-30 minutes per light. Headlight conversions may require 1-2 hours and possibly headlight housing modifications. Basic tools needed include screwdrivers, wire strippers, electrical tape, and a test light or multimeter. Some LED headlights require additional wiring harnesses or adapters specific to your truck model. Always disconnect the battery before starting any electrical work.

How long do LED lights actually last compared to traditional bulbs?

Quality LED lights typically last 30,000-50,000 hours compared to 1,000-2,000 hours for halogen bulbs. In real-world trucking conditions, this translates to 5-10 years of service for most LEDs versus annual replacements for traditional bulbs. However, cheaper LEDs may fail within 1-2 years due to poor heat dissipation or low-quality components. Look for lights with aluminum housings and proper heat sinks for maximum longevity.

Are all LED lights DOT approved, and will they pass inspection?

Not all LED lights are DOT approved. Look for lights clearly marked with "DOT" or "SAE" certification stamps. This is especially critical for headlights, tail lights, and clearance markers. Non-certified lights may cause inspection failures and potential fines. Aftermarket LED headlights must meet specific beam pattern requirements - avoid cheap imports that scatter light improperly. When in doubt, check with your state's specific commercial vehicle inspection requirements.

What's the real difference between cheap and expensive LED lights?

Premium LED lights feature better waterproofing (IP67 or IP68 ratings), thicker lenses that resist cracking, UV-resistant materials that won't yellow, and internal components rated for extreme temperatures (-40F to 185F). Cheaper lights often use thin plastic housings that crack within months, poor seals that allow moisture intrusion, and LEDs that dim or fail prematurely. The initial savings on budget lights typically result in more frequent replacements and potential downtime.
