Buying Guide

Voltage and vehicle compatibility

Confirm the bulb is 12V or matches your vehicle's electrical system and check fitment for trailers, trucks, or specific models like Ram cab applications

LED vs. incandescent

LED marker lights use less power, last longer, and often include waterproofing, while incandescent may be cheaper but require more frequent replacement

Size and mounting style

Match diameter (e.g., 2" or 2.5") and mounting type such as round grommet, beehive housing, or cab roof mount to ensure proper fit and easy installation

Lens color and visibility

Choose red for rear/side rear and amber for side/front marker applications to meet standard signaling and improve daytime/nighttime visibility

Pack quantity and use case

Consider multi-packs (5–10 pieces) for replacing all marker lights on a trailer or truck at once, which can simplify wiring and color matching

Build quality and environmental rating

Look for waterproof or weather-resistant housings, solid pigtail/grommet fittings, and durable lenses for exposure to road and marine conditions
