Buying Guide
Key considerations when choosing LED clearance marker lights:
- Size and fit: Match the unit diameter and mounting depth to your trailer or vehicle footprint.
- Power and wiring: Confirm voltage rating (commonly 12V) and the wiring configuration (2-prong, screws, or grommets).
- Visibility: Choose amber for side markers and red for rear markers to conform with typical signaling conventions.
- Durability: Look for waterproof sealing, UV resistance, and robust housings for road exposure.
- Installation: Consider included mounting hardware, grommets, and the ease of flush versus surface mounting.
- Quantity vs. coverage: Bulk packs are cost-effective for fleets; smaller sets suit single-vehicle upgrades.
- Compatibility: Verify with your vehicle’s existing light housings and any DOT or jurisdictional requirements.
