Freightliner FLD SBA Lights

Frequently Asked Questions About Freightliner FLD SBA Lights

Will these lights fit my specific FreightlineLD model year?

These SBA (Set Back Axle) lights are designed specifically for Freightliner FLD 112 and FLD 120 models from 1989 to 2007. The most common fitment issues occur with 2003-2007 models that have aftermarket bumpers or custom modifications. Before ordering, verify your truck has the original SBA bumper configuration with the standard light cutouts measuring 4 inches round for turn signals and 6x2 inches for clearance lights.

Are these lights DOT approved and what about the lens material quality?

All lights in this category meet DOT/SAE compliance standards for commercial vehicles. The lenses are made from either polycarbonate or acrylic materials, with polycarbonate options offering superior impact resistance and UV protection. Look for lights with welded housings rather than glued assemblies, as these provide better long-term weather sealing. Premium options feature hard-coated lenses that resist yellowing and cracking from sun exposure.

Can I upgrade to LED without rewiring my truck?

Most LED upgrade options are designed as direct plug-and-play replacements for your original incandescent lights. However, some trucks may require LED-compatible flashers to maintain proper turn signal flash rates. No rewiring is typically needed, but adding a load equalizer or electronic flasher relay (around $20-30) may be necessary if you experience hyper-flashing after LED installation.

What mounting hardware comes with these lights and what else might I need?

Standard light kits include mounting grommets and basic hardware for OEM-style installation. However, many customers find they need additional items such as pigtail connectors if existing wiring is damaged, dielectric grease for connections, and rubber mounting pads for vibration reduction. Chrome bezels and visors are typically sold separately. Plan to spend an additional $20-40 on supplementary hardware and supplies for a complete installation.

How difficult is the installation and what tools are required?

Installation difficulty varies by light type but generally takes 30-45 minutes per light for experienced mechanics. Basic hand tools needed include wire strippers, crimping tools, socket wrenches, and a test light or multimeter. The most challenging aspect is often accessing the back of the bumper for wiring connections. Many drivers report better results removing the bumper entirely for installation, which adds 2-3 hours but ensures proper wire routing and secure connections.
