Optronics Trailer Light Kits - Incandescent
Optronics incandescent trailer light kits provide everything needed to properly light your trailer, delivering the brand's proven reliability in traditional bulb-based lighting solutions. The company specializes in interior and exterior LED, incandescent and fluorescent lighting for the truck, trailer, marine, RV, heavy duty and transit vehicle markets, making their incandescent kits a time-tested choice for trailer owners who prefer conventional lighting technology.
Complete Kits for Every Trailer Width
These kits include tail lights, amber clearance lights, amber reflectors, license plate bracket, 25' wiring harness with 4-pole connector, and mounting hardware. Optronics offers configurations for both under-80-inch and over-80-inch trailers, ensuring DOT compliance regardless of your trailer dimensions. A trailer that is over 80 inches wide is required by DOT regulations to have rear clearance lights, and Optronics over 80 inch taillight kits have the side clearance light built into it, simplifying installation while meeting federal safety standards.
Submersible Design and Reliable Construction
One of the defining features of Optronics incandescent kits is their submersible, waterproof construction. These waterproof trailer light kits are designed for trailers that need to operate in challenging conditions, including boat trailers frequently backed into water. The lights use standard 1157 bulbs for tail lights and 168 bulbs for marker and clearance lights, making replacement bulbs easy to source at any auto parts retailer. The kits feature hard-wired connections with color-coded wiring—yellow for driver side stop/turn, green for passenger side stop/turn, and brown for tail functions—along with self-grounding designs that simplify installation.
Why Choose Incandescent Technology
While LED technology dominates modern trailer light kits, Optronics continues to manufacture incandescent options for trailer owners who value simplicity, affordability, and ease of repair. Incandescent bulbs are universally available, cost-effective to replace, and operate reliably in extreme temperature ranges. For vintage trailers, agricultural applications, or utility trailers where budget is a primary concern, these kits deliver DOT-compliant lighting without the complexity or initial investment of LED systems. As the fastest-growing RV, motorhome and trailer lighting manufacturer in the U.S., Optronics International was founded in 1972 and brings decades of engineering expertise to its incandescent product lines.
Installation and Compatibility
Optronics incandescent trailer light kits are designed for straightforward installation with included mounting hardware and detailed wire color specifications. The 25-foot wiring harness provides ample length for most trailer configurations, and the standard 4-pole flat connector ensures compatibility with virtually all towing vehicles. The license plate bracket integrates seamlessly with the driver-side taillight mounting pattern, and the included amber reflectors meet FMVSS requirements for side visibility. Whether you're building a new utility trailer, restoring a classic boat trailer, or replacing failed lighting on an equipment hauler, these kits offer proven reliability backed by Optronics' industry-leading reputation.
