Frequently Asked Questions About Freightliner FLD SBA Cab Lights
What year models of Freightliner FLD are compatible with these SBA cab lights?
These SBA cab lights are designed to fit Freightliner FLD models from 1989 through 2007. The mounting pattern remained consistent throughout these production years, making installation straightforward. However, some early 1989-1991 models may require minor modifications to the wiring harness. Always verify your specific truck's configuration before ordering, as custom or modified cabs may have different requirements.
How difficult is the installation process, and what tools do I need?
Installation typically takes 2-3 hours for someone with basic mechanical skills. You'll need a drill with metal bits (5/16" and 3/8"), wire strippers, crimping tools, and basic hand tools. The most challenging part is drilling the mounting holes accurately - we recommend using the provided template and double-checking measurements. Most customers report that running the wiring through the headliner is the trickiest step, but using a coat hanger as a fish tape makes it much easier.
Are these lights DOT approved, and what's the difference between amber and clear lenses?
Yes, all our Freightliner FLD SBA cab lights meet DOT requirements for commercial vehicles. Amber lights are required by federal regulations for vehicles over 80 inches wide and must be used on the front of the cab. Clear lights can be used for additional illumination but cannot replace the required amber markers. Many drivers choose amber for the front three positions and clear for the rear two for enhanced visibility.
What's included in the complete kit, and will I need additional parts?
Each complete kit includes five cab light housings, pre-wired LED bulbs, rubber gaskets, mounting hardware, wiring harness with ground wire, installation template, and detailed instructions. You won't need additional parts for a standard installation. However, if your truck has aftermarket visors or custom bodywork, you may need longer screws or additional wire length, which we can provide separately.
How do these lights hold up to weather, and what maintenance do they require?
Our SBA cab lights feature heavy-duty ABS plastic housings with UV-resistant coating and sealed lens designs that prevent water intrusion. The rubber gaskets should be inspected annually and replaced every 3-4 years to maintain waterproofing. LED bulbs typically last 50,000+ hours, far outlasting traditional incandescent bulbs. To maintain appearance, clean with mild soap and water, avoiding harsh chemicals that can cloud the lenses.
